Best Mode of Carrying Out the Invention A washing system in accordance with the present invention shown in Figure 1 and includes for example, a diverting unit DU connected with a water supplying pipe WS, a hand-held washing device WD, and a shower head SH. The hand-held washing device in accordance with the present invention has a housing 1 shown in Figure 2 and formed of one piece with a holder 2. A holder 2 has a ring groove 3 with a seal 4 at its end. The outer surface of the holder has a groove 5 with spherical depressions 6 and 7 at its ends. The holder 2 is formed of one piece with the housing portion which forms a rotor chamber and the housing portion which forms a substance chamber, the chambers separated by a partition having a substance supply opening. A handle 8 is slidingly fitted on the holder and has one end provided with a thread 9 for connection with a flexible hose. The front part of the handle is provided with a spherical fixing member 10 shown in Figure 2. It is spring- biased by a spring 11 toward the groove 5. The spring is arranged in an opening 12 and fixed by a rivet 13. In the zone of connection of the holder with the housing a water pressure opening 14 or an injector shown in Figure 4 is arranged at an angle relative to the axis of rotation. Its diameter and length are selected in accordance with the law of hydraulics to provide a concentrated flow of water. The housing is subdivided by partitions 15, 16, 17 into two sections. The first section 18 is provided for preparing perfumary of medical solutions. It has a water pressure opening 19 and an adjusting valve 20 with a needle tip 21 which overlaps the outlet conical opening 22 under the action of a threaded block 23 with a seal 24. The other end of the member 25 which is opposite to the needle point 21 operates for piercing of a shell of substance-containing elements, such as for example hollow spherical containers which parfumery, medical and other substances. The valve 20 which is arranged on an axial 26 of the partition 15 is open by the spring 27. The second section 28 is a working section of the rotor. The rotor 29 has eight open blades 30 which are shown in Figure 4 and arranged on a disk 31 at an angle to the axis of rotation. The rotor has a hollow pin 32 which is connected with the disk of the slide of the blades and ends in a gear 33. The partition 16 which separates the second and the third sections has a central hub 34 shown in Figure 2. A pin of the rotor 32 with the gear 33 extends through the opening of the hub 34 into the third zone and engages with three gears 36 arranged on three hollow axials 37 mounted on the partition 16 so as to form a planetary transmission together with a gear 38 having inner teeth. The outer surface of the gear 38 has a 2° cone (morse cone) and is used for mounting of a rotary tool. The planetary mechanism is closed by a flange 17 which has a conical surface 39 for guiding the tool when it is to be mounted. The flange is arranged on two hollow axles 37 which have a hollow surface 40 and is centered by three openings 41. A hollow hub 42 is arranged at the center of the flange. The side surface of the flange has a conical surface 43 which, in combination with the surface 44 of a diffusor 45 shown in Figure 3, forms an opening of a shower stream. The diffusor 45 has three projections 46 with openings 47 which coaxial with the openings 40 and 41 in Figure 2. Conical grooves 48 are provided on the lateral conical surface of the diffusor in three sectors over its periphery. In combination with the surface 43 of the flange 17 the conical grooves 48 form openings for a shower stream 49. The mounting of the diffusor to the flange is performed by a central split axle 50 in an opening 51 by a snap on. Turning of the diffusor from the position "spray" to the position "jet" is performed by a handle 52 and fixed by a stop 53. The rotary mechanism located in the third zone is protected by a side wall 54 of the cylindrical position of the housing 1 , with a side gap 55 formed between the wall of a cylinder and a lateral conical surface 39 of the flange 17, The working tool 56 is engaged in this gap when the device is used for a mechanical treatment. While Figures 2-4 show the washing device in which substances are introduced into water, the inventive system can have a separate substance introducing device as shown in Figures 5-9. The device for introducing substances into water of the inventive system has a housing which is identified with reference numeral 101. It is connectable with a water source, for example with a pipeline by a nut 102 with an inner thread and has a sealing member 103 which is shown in more detail in Figures 12 and 13. The nut 102 is fixed to the housing 101 by a threaded flange 104 which has an inner hexagonal cross- section and is provided with an outer seal 106. The housing 101 has a first chamber which is identified with reference numeral 107, a partition 108, and a second chamber 109. The partition 108 separates the chambers 107 and 109 from each other and has a central opening. The housing 101 has an outer threaded portion 110 for attachment of a showerhead or any other consumer device. The housing has two throughgoing openings 111 and 112 which are located at both sides of the partition 108. Each opening 111 and 112 is provided with an annular recess 1,13. Seals 114 formed for example as O-rings are located in the recesses 113. The device further has a threaded flange or valve 115 which is connected to the housing 101 turnably via a shaft or rivet 116. The upper wall of the flange 115 also has two flange openings 119 and 120. Reference numeral 121 identifies a container with a substance to be introduced into water. It has an outer thread with which it is screwed into the inner thread of the flange 115 and sealed by a seal. The flange 115 is turnable around an axis of the flange between an operative position in which the flange openings 119 and 120 coincide with the housing openings 111 and 112 so that water flows from the first chamber 107 into the container 121 , is mixed in the container with the substance, and then the mixture flows into the second chamber 109 and to a consumer. The flange 115 can be turned to an inoperative position in which the openings 119 and 120 do not coincide with the openings 111 and 112, so that there is no communication between the chambers 107 and 109 and the interior of the container 121. A control member 124 is arranged in the opening of the partition 108. It can be formed for example as a diagram shown in Figure 5. When water flows through an opening of the diaphragm 124, a resistance is provided so that a pressure difference is produced between the first chamber 107 and the second chamber 109. This difference depends on the size of the opening 125 of the diaphragm. On the other hand, a flow rate and concentration of the solution from the container 121 depends from the pressure difference between the chambers 107 and 109. Since water systems have various pressures, the pressure difference between the chamber 107 and 109 can be very high if the opening in the partition between the chambers is constant, and at low pressures the pressure difference can drop to zero so that there will be no supply of the solution, while in the conditions of high pressure difference the solution will be immediately washed out from the container. The diaphragm 124 is composed of elastic material, for example rubber, and its hardness is selected experimentally so as to control the pressure difference. When there is a high water supply pressure, the opening 125 of the diaphragm opens so as to increase a water flow rate, while in condition of low water supply pressure the opening 125 of the diaphragm narrows so as to maintain the pressure difference. The device in accordance with the present invention is very convenient for installation in a shower system since it provides a convenient location of the container 121 for the user. For this purpose the nut 102 is utilized in combination with the sealing member 103 which is formed as a plastic or rubber bushing and simultaneously forms a seal and a fixator. The fixation is provided by the polygonal (for example hexagonal) cross-section of the end of the sealing member 103 which is inserted into the inner polygon of the bushing 104, so that the housing can not turn any longer on the pipeline. The seals 114 arranged in the recesses 113 of the throughgoing housing openings 111 and 112 prevent leaks between the flange 115 of the container 121 and the housing 101. Therefore, a reliable tightness and a simple manufacture are guaranteed. It is to be understood that the seals 114 can be instead arranged in the flange openings 119 and 120. When the device is used for technical purposes, it is necessary to prevent a backflow of the substance into the pipeline. Figure 6 shows another embodiment of the present invention. In accordance with this embodiment, the partition between the chambers 107 and 109 has a cylindrical opening 127 and a conical opening portion 128. The control member 129 is arranged in the conical opening portion 128 and is spring-biased by a spring 130. A perforated further partition 131 provided with openings 132 is located in the region of an outlet of the housing 101. When water enriched with the substance flows out of the housing 101 , the control member 129 which is formed as a conical member deviates from the conical opening portion 128 so as to form a gap therebetween to allow water to flow from the chamber 107 into the chamber 109, and thereafter through the openings 132 of the partition 131 , while the solution of the water with the substance flows from the container 121 through the aligned openings 119 and 112, In the event of a back pressure, the control member 129 is firmly pressed against the conical opening portion 128 so that the opening 127 between the chambers 107 and 109 is closed, and also the throughgoing housing opening 112 is closed as well. As a result, the solution can not flow back into the chamber 107 neither from the chamber 109 nor from the container 121. In the embodiment of Figures 7 and 8 a housing 141 having openings 142 and 143 is connected immovably with a flange 144 which has openings 145 and 146. A slider 147 provided with openings 148 and 149 is turnable around an axis which is perpendicular to the axis of the flange between an operative position in which the openings 142, 145, 148 and 143, 146, 149 coincide with one another to provide throughgoing flows, and an inoperative position in which the openings 148 and 149 are angularly displaced and a material of the slider 147 interrupts the communication between the openings 142, 145 and 143, 146 correspondingly. The device in accordance with the embodiment shown in Figure 9 substantially corresponds to the device of the embodiment of Figures 7, 8. The only difference here is that in the device shown in Figure 9 the slider 147' is not turnable, but instead is translatorily displaceable between the operative and inoperative position, In accordance with the present invention, a device is provided (Figures 5, 10-13) for connecting the water supplying element or pipe WS with the water issuing element or the housing 101. The device first of all includes a connecting element including a the connecting member formed as the nut 102. The nut 102 is hollow and has an inner thread with which it is threaded on the outer thread of the water supplying element or the pipe WS. The nut 102 also has a shoulder which is identified with reference numeral 211 , The other part of the connecting element is the bushing 104. The bushing 104 has a shoulder 213 behind which the shoulder 211 of the nut 102 engages. It further has an axial extension 214 which is provided with an outer thread 215 threadable into the inner thread of the water issuing element or housing 101. The bushing 104 has an inner hole 216 having a polygonal cross-section, for example a hexagonal cross-section, as illustrated in the shown embodiment. The interengagement of the shoulders 211 and 213 provides the connection of the bushing 104 to the nut 102, the inner thread of the nut 102 provides a connection to the water supplying pipe WS, and the outer thread 215 of the bushing 104 provides a connection to the water issuing element or housing 101. The device for connecting the water issuing element 101 to the water supplying element WS further includes the sealing member 103. composed of elastic material, for example rubber, plastic etc. The sealing member has sealing portion which extends transversely to an axis of the sealing member and is identified with reference numeral 218. The sealing portion 218 is formed as a disk. The sealing member further has an extension 219 v/hich extends in an axial direction. The extension has an upper polygonal surface 220, for example a hexagonal surface with an outer cross section substantially corresponding to the inner polygonal cross-section of the hole 216 of the bushing 104. An intermediate portion 221 which is formed as a cylindrical hollow portion is also provided in the sealing member 103 and connects the sealing portion 218 to the surface 220 which forms a rotation preventing portion. in an assembled condition the sealing portion 218 of the sealing member 103 abuts with its right face as seen in the drawings against the left face of the portion 213 of the bushing 104. The intermediate portion 221 of the sealing member 103 is received in the cylindrical opening 222 of the bushing 104, and the hexagonal rotation preventing surface 220 of the sealing member 103 engages in the hexagonal inner hole 216 of the bushing 104. During turning of the nut for connecting the water issuing pipe 101 to the water supplying pipe WS, the right end face of the water supplying pipe WS abuts against the seaiing portion 218 of the sealing member 103, and since the polygonal surface 220 of the sealing member 103 engages in the polygonal hole 216 of the bushing 104, the sealing member 103 as a whole can not rotate. A tight sealing of the system is provided. In accordance a further modification, the connecting device is used for the diverting unit DU shown in Figure 14. The diverting unit has a housing 251 and a plunger 252 provided with a handle 253 and two sealing portions 254, 255, In the shown position the plunger is lifted, and the lower sealing portion interrupts the communication between passages 256 and 257, but opens the communication from the passage 255 into the passage 258, for example to the hand-held washing device. In the lowered position the sealing portion 255 will seal the passage 258, and the water will flow from the passage 256 into the passage 257, for example to a showerhead. Here the connecting device also includes the nut 102, the bushing 104, and the sealing member 103 formed so that it seals the connection and also prevents rotation. In accordance with the present invention, piercing means are provided for piercing a capsule in which a product can be accommodated (Figure 5). The capsule is identified as a whole with reference numeral 301 and has an outer wall 302 which forms an inner chamber filled with a product 303. In order to rupture the wall 302 of the capsule 301 , the capsule is pierced by piercing means. In accordance with the present invention the piercing means is formed for example as a sharp projection 304. The piercing means or the sharp projection 304 is formed in the region between the water issuing pipe WS and the container. In the shown embodiment, the piercing projection 304 is formed on the central shaft which is formed for example as a rivet 116. The rivet 1 16 has a central cylindrical portion 305 with an upper end which is immovably pressed in a central blind hole and extends through a central opening of the transverse portion of the valve 115 freely, so that the valve element 115 can turn relative to the rivet. The rivet 116 further has a head 306 which is wider than the central portion 305 and engages under the transverse portion of the valve 115, In the shown embodiment, the sharp projection 304 is formed on the head 306 of the rivet 1 16. The rivet 116 thus performs two functions, namely for turnably connecting the container with the water issuing pipe or housing 101 or more particularly for turnably connecting of the valve 115 attached to the container relative to the water issuing pipe or housing 101 on the one hand, and for forming the piercing means for piercing the capsules with the product on the other hand. As can be seen from the drawing, the piercing projection can be provided also or only of the water issuing pipe or housing 1 (304) on the connecting nut (304"), on the valve (304"') on the container (304""). When the capsule is pierced, it can be thrown into the container, and the product gradually is released from the pierced capsule into the container and additionally is washed out from the pierced capsule by water. The product can be also squeezed out from the capsule by a user. Also, the capsule wall can gradually dissolve in the container by water. A container for introducing substances into water as shown in Figures 15 and 16 is identified as a whole with reference numeral 401. The container 401 is formed as a bottle or the like. It has a wall 402 and a neck 403. The container in accordance with the present invention further has piercing means which are identified as a whole with reference numeral 404. The piercing means can include at least one sharpened or pointed projection 405, or several such projections. In the embodiment of Figures 15 and 16, the projections 405 are arranged on an inner surface of the neck 403 of the container 401 , Also, they are made of one piece with the neck 403 during the manufacture of the container 401 , The projections 405 are spaced from one another in a circumferential direction of the neck 403. When a capsule 406 which contains a product for showering, bathing and the like is forcedly introduced into the container through the neck 403, the wall of the capsule 406 is pierced by the projections 405, and the product from the capsule 406 flows into the interior of the container. The container filled with the product can be used for pouring its product into a bath, on a user taking shower, or into a showering equipment, for example into a shower water supplying element. The device in accordance with the embodiment shown in Figures 17 and 18 also has a container 401', and means AQ4' for piercing the capsules, However, piercing means are formed differently. The device is provided with a separate element 407 which can be formed as a disc with a plurality of openings 408, The disc 407 can be snuggly fitted inside the container 404'so as to be firmly held by friction between the outer circumferential surface of the disc and the inner circumferential surface of the wall of the container. A sharpened or pointed projection 409 is provided in the center of the disc 407. When the capsules 406 are passed through the neck of the container 404' downwardly, their walls are pierced by the projection 409 and their content is emptied into the container 404' and flows through the openings 408 downwardly, While in the embodiment of Figures 15, 16 the piercing means 404 are arranged in the region of the neck of the container and in the embodiment of Figures 17, 18 piercing means are supported by the peripheral wall of the container, the device in accordance with the embodiment of Figure 19 is somewhat different. The device shown in Figure 19 has a container 404" with a side wall 402, a neck 403, and a bottom 410. The piercing means 404" include at least one sharpened or pointed projection 411 which is formed on the bottom 410 on the container 404". The capsule 406 can be introduced into the container 404" through the neck 403 and then pressed against the projection 411 by hand or by an additional pressing element 412, In the shown embodiment the element 412 is a part of a plug 413 having a lid 414. When the pressure is applied onto the capsule 406 from above toward the projection 411 , the capsule wall is pierced through and the capsule content is empties into the interior of the container 404". In the embodiment shown in Figures 20, 21 , the device has a container 404"" which is arranged on a water supplying conduit 415 and normally closed by a lid 416. The piercing means 404"" are formed here by a sharpened or pointed projection 417 which is arranged on a transverse strip 419. In use water is supplied through the conduit 415, the lid 416 is removed and the capsules are introduced into the container 404"" and pressed against the projection 417 so that the content of the capsules flows into the container, in which it is mixed with water of an additional water stream supplied into the container, and thereafter flows into the conduit 415. In the actual system water can be supplied from a common source and then branched into a main water stream which flows through the conduit 416 and an additional water stream which is supplied into the container 404"", is enriched with the capsule content and thereafter flows into the conduit, It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the types described above. While the invention has been illustrated and described as embodied in washing device, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention. Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention. What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.

AMENDED CLAIMS [received by the International Bureau on 19 March 2000 (19.03.01); original claim 1 amended; remaining claims unchanged (1 page)] A washing system, comprising a hand-held washing device which includes a housing; a rotor rotatably arranged in said housing and having a plurality of blades so that when water passes through said housing said rotor rotates under the action of water, a washing tool attached to said rotor so as to rotate together with said rotor and to allow water to exit from said housing; an elongated holder connected with said housing and having an axis and an axial opening through which water passes: and a handle having an axial opening through which water passes and being axiallv telescopably movable on said holder so as to increase and reduce a joint length of said handle together with said holder to make therefore comfortable washing a part located close to said washing device when the joint length of said holder and said handle is reduced and to wash a part located further from the device when the joint length of said holder and said handle is increased, said housing having a first housing portion which forms a chamber for said rotor, a second housing portion which forms a chamber for accommodating a substance for introducing into water, and a partition separating said chambers from one another and having an opening for supplying the substance from the second chamber into the first chamber, said holder being connected with both said housing portions. STATEMENT UNDER ARTICLE 19 (1) In the International Search Report , U.S. Patent No. 4,734,954 to Greskovics, et at was applied against the original claims. With the Amendment, applicant has amended claim 1 , the broadest claim on file. Claim 1 as amended clearly and patentably distinguishes the present invention from the reference cited by the Examiner as being a document of particular relevance. The washing system in accordance with the present invention has a housing with a first housing portion forming a chamber for the rotor, a second housing portion forming a chamber for a substance to be introduced into water, a partition separating the chambers and a holder connected with both housing portions. Also, the handle and the holder of the inventive washing system are hollow and water passes through them, and the handle is movable telescopably on the holder. In contrast, the device disclosed in the patent to Greskovics does not have separate chambers for water and for substance introducible into water, with a partition between the chambers and a holder connected to both housing portions. Also it does not have a handle and a holder which are both hollow and through which water passes, and which are movable relative to one another in an axial direction. In contrast the holder of the Greskovics patent is not used for passing of water, it is not telescopably extendable but instead has a hinge so that one part of the handle is turnable relative to the other part. This reference does not teach the new features of present invention as defined in the amended claim 1.
