Description: Vibratory pump. This invention deals with improvements done in vibratory pump apllicable to repression of li, quids and these liquids were develope to improve its - performance and utilization. It's alrealdy known a vibratory pump constituted, essencially, by a skeleton of syntetic mate rial or others, composed by an inferior part and a supe rior one linked, in middle level, by means of ligation - which is finished in the inferior part by a static eLetric bobbin, covered with resin and that one acts on a movel eletric bobbin, which is set in a inferior extremity of an axial oscillating member which middle region is sup. ported and slides in a bearing and it has a flexible me - - brane, this one is near to the periphery sent close to the skeleton in which the superior extremily the said axial ascillating member which supports a cupping glass also flexible, and this one in cooperation with the said flexible membrane and a part of the skeleton delimited by - a variable volume chamber which communicates itself with the exterior through an admission valve and with a su perior repression tubulation, said valve is constituted by a superior central chamber, that communicates itself with the variable volume chamber, through a movement of - the cupping glass set in the axial member extremity and with the exterior through opening on which acts the se, cond cupping glass set on the wall of the constitutive valve. In the conveneional building of this - kind of pump the fixed eletric bobben is flaced in the interior of the skeleton and cavered with resin,in these conditions it warms itself on levels above of that one that would be ideal. The first improvement introduced in - the pump despases the static part of the bobbin in a water refrigeration chamber that helps the maintenance - of the temperature in the aceptable limits. In the conveneional building of the pump, as it was described, the adjacent extremities of - the skeleton are linked by means of ligation constituted by external flanges, link screw receiver, solution that obliges the else of an enoi ous number of screws each ti. me it's necessary open a clese the pump in the maintenace work and others, operation that's considered boring and - it could be eliminate. Having in mind this trouble and as a way of overcoming it, the means of ligation of the skele ton parts, in this improvement, consist in a extreme lar ge of the inferior skeleton in which an external flange- - of the superior part of the skeleton and on it there's a ring fixed in the internal side of the extreme large part of the inferior skeleton,through a thread or mortise. This building makes easy the open and closing operations of the skeleton, avoiding troubles - - that happen in the conveneional building. In the conveneional building of the pump the main membrane presents a prolongation that ex tendes from the inferior extreme of the water repression chamber untill the interligation region between the su perior and inferior parts of the skeleton,where a flange - is coupled to a profiler tooth of the superior flange - and a extreme flange of the bearing of sustentation of the central oscillating member, which is interlinked between the flanges of the parts of the skeleton. This building involves an use of ma - terial and labour that could be reduced without any da mage for the unity work. The main membrane, in this improvement^ is provided of a profilek flange placed in the inferior- extremity of the water repression chamber that is inter - linked between the internal tooth of the superior part of skeleton and the ring placed on the bearing of susten tation of the oscillating member, that acts on the membrane. In this improvement the covered packer - of the static part of the eletric bobbin is fixed in the internal region of the inferior part of the skeleton through the ultrasound, the two constitutive parts of the inferior and superior part of the skeleton ar inter linked by auto-solder and others, what's called simple - - and safe ligation. Grood results gained with the pump that's provided of an admission valve as described, new studies about its work during its operation took to the development of a new valve of admission and emission of - the liquid that presents better effect than the eonveneio nal building,as well as a building extremely simple that akes easy the pump manufacturer. The draws enclosed show the improvement in the vibratβry pump, matter of this patente,in which. PIGHEE 1;- shows the pump as a plan. - FIGURE 2:- Shows a longitudinal cut - A-A indicated in the previous fi gure. FIGURE 3:- Shows a detail of the means of interligation between the ske - leton, seen as a plan. FIGURE 4;- Shows a cut B-B, indicated- in the previous figure, in which is shown neans of interligation - between the parts of skeleton. - FIGURE 5:- Shows a sight "C" indicated in the previous figure. FIGURE 6;- Shows a lateral sight of the admission and emission valve of the vibratory pump - with separated parts. - FIGURE 7; Shows a sight of the emission and admission valve stablished. As the figures above show, the vibra¬ tory pump, described in this patente, is constituted by- a skeleton, essencially, cylindrical and edreloned of - synthetic material or others, composed by regions of the inferior (l and (2) superior skeleton interlinked at an average level, by means of ligation (3) the said skeleton (l-2) finishes, in its inferior part (l) an static eletric bobbin (4) covered by synthetic resin (5) and that ane - - acts on a movel bobbin (6) set in the inferior extremity of an oscillating member (7) disposed axially in the ske leton (1-2) with a medium region supported and capable of sliding on the bearing (8) supported between the inferior (l) and superior (2) of the skeleton and this member is supported by a main inferior membrane (9) that limits in - cooperation with the superior part of the skeleton, a re¬ gression chamber of variable volume (10) communicating - with the exterior through a superior central admission val ve (ll) and with regression duet (12);the said admission - valve composed by a chamber communicating with the repres, - sion chamber of variable volume through a flexible cupping glass (13) set in the superior extremity of the oscillating axial member, communicating with the exterior through ope ning (14) on which acts a second superior cupping glass - (15) set on the definer wall of the admission chamber. - The first improvement introduced to the vibratory pump, indudes a refrigeration chamber (16) of the static eletric bobbin (4) nd for that, the inferior part (l) of the skeleton is divided by a staindess steel membrane (17) that is with peripheric part sent in the in - ternal face of the said inferior part of the skeleton(l) disposed between the static eletric bobbin (4) and the mo vel eletric bobbin (β) that divides the inferior region - of the skeleton (l) and a superior region of the skeleton (18) and in the inferior refrigeration chamber that works - with water (16) that contains the static eletric bobbin - (4) and communicates itself with exterior by opening means (19). The second improvement introduced to - the vibratory pump, consists in the means of ligation (3) - of the inferior part of the skeleton (l) to the superior part of (2)instead of being comprehended by the conven cional flanges and screw are composed by a an extreme,- prolongated and short region (20) of the inferior part - of skeleton (l)in which an external extreme flange a&jas ts(2l) to the superior part of the skeleton(2) and set - on the said external extreme flangs is a set a profiler- ring that is the room between the external surface of the superior part of the skeleton (2) near to the flange and the internal surface of the prolongated region (20) and and couples itself to the said prolongated region (20) - - through the screw thread (23) and pre-determinated, res, pectivaly, in the building of the means of ligation (3) - (figures 3,4 e5) instead of the coupling between the ring (22) and internal face of the prolongated region be done- by the screw thread (23) and (24) can be introduced radial - pins (25) regularly distant in the ring external face (20) that couple themselves in correspondents grooves set in the internal face of the extreme prolongated region (20)- these grooves have the " " form composed by an area dispo sed in longitudinal direction of the pump, extended from - the free border of the prolongated region to the medium - level, from which derives a perpendicular region (27) that is the circunferencial part of the skeleton. At last, the bait profeler ring (22)is with its surface opposit to that one which is on the flan - ge (21) of the part of inferior skeleton (l) that's provi ded of a circunferencial arrangement of circular lowed re gularly distant (28) and intercalated by radial triangu - lar wing (29)responsible by the ring movement in the open ing and closing operations. - Other improvement introduced in the vi bratory pump,consists of a main membrane determination - (9) that instead of being done with a prolongated part that goes until the level between the inferior (l) and- superior (2) parts of the skeleton and with the interca¬ lated extremity between the said parts as usually occurs, - is composed by a profiler flange (30) of the said main - membrane (9) that's intercalated between by a teeth (31) composed by langer (32) and shorter (33) parts of supe rior part of the skeleton (2) and a ring which is set on the sustentation bearing of the oscillating member (7). - In this improvement, the cover (5) of the static eletric bobbin (4) is linked to the skeleton- (1-2) through a soldering by ultrasound or others (35) - and it can be substitued by electrostatic recovering to enlarge the refrigeration area and the parts that co - pose the skeleton, inferior (l) and superior (2) have their constitutive parts linked by auto-gluing andothers (36). Another improvement introduced to the vibratory pump, consists of substituting an admission - - valve of superior central liquid (ll) by an emission and admission valve (37) (figures 6 e 7) composed by an as se bly ring (38) that is provided by a part of its ex ternal surface, of a screw thread (39) that is put in the correspondent screw thread (40) set in the internal- - surface region of the skeleton (2) contiguous to the outtet (l2) and in the free extremity of the said as sembly ring (38) there's an external brim (41) on which is set an extreme internal short brim (42) of a membrane of flexible rubber ring type (43) that is set in the - said assembly ring and recovers in its internal part, openings (44) that go from the part of the superior skeleton of entry water in the variable volume repression chamber (10). From the assembly ring extremity (38) that's opposit to that one which is set on the flexible - - rubber ring (43) is an internal orthogonal brim (45) from which a region in cup form is prolongated (46)co-axial to the assembly ring (38)and in its deep (47)is a central opening (48)in which is couple and fixed a pin (49)in the external face of the flexible rubber membrane in cup form - (50)that's placed and adjusted in the internal region of the cup form (46)of the assembly ring (38); the said flexible rubber cup (50) has a lateral wall (51) that covers in the internal side the openings that are in the lateral wall (53) of the cup region (46)of the assembly - ring (38)through which the water contained in the repres, sion chamber (10) passes by the outlet pump. When the axial oscillating member of the pump changes its place descendantly,it enlarges the repression chamber volume (lθ)and causes a depression in - the internal part of the chamber that tries the flexion - of the flexible rubber ring (43) to the deoppilation of .the openings (44) and the consequent entry of a portion - of water to the internal part of the repression chamber - (lO)and simultaneously, tries the lateral wall compression - (5l)of flexibe rubber cup (50) that meets the outlet open ing (52) of the water repression chamber (lθ),and close - them. On the contrary, when the axial member changes its place ascendantly, it reduces the repression- - chamber capacity,it compresses its internal part and also causes the compression of the flexible rubber ring (43) - that meets the openings (44) that are clθsed and simulta neously, the flexion of the flexible rubber ring (50)that opens the openings (52) throug which a part of the water of the repression chamber (10) passes to the outlet (12).
