Abstract: 876,673. Stuffing-box substitutes. HUHN, F. A. Dec. 20, 1957 [Nov. 15, 1957], No. 39609/57. Class 122 (5). A sealing device for a rotatable shaft 10, Fig. 3, such as a turbine shaft 10, comprises an annular radially divided casing 12 consisting of an end wall 13, cylindrical wall 15 and cover 20 so as to constitute at least one annular chamber 24 containing non-rotating self-lubricating sealing members 36 separated by at least one intermediate annular member 26 which is formed from a number of segments pressed axially against a shoulder 28 on the wall 15 by bolts 62, Fig. 2, in order to produce plane radial contacting surfaces for the sealing members across the points of the segments. As shown in Fig. 2, the member 26, which may be of bronze or synthetic plastic material, is provided with an annular groove 56 having a tapered lower surface 58 against which abut the corresponding tapered ends of the bolts 62 screwed into the wall 15. If desired the chamber 24 may be subdivided by two or more members 26. The sealing members 36, which may be of carbon, are each in the form of a pair of rings held in assembled position by a. pressure ring 38 engaging the conical outer surfaces of the rings so that a gap 52 separates the rings. Each sealing member with its pressure ring 38 is split into a number of segments which are held together by an enclosing member consisting of several springs 44 connected together by members 46 and, in order to limit the endwise movement of the two rings 36 under the action of the springs, the ring 38 is provided with flanges 40 engaging in slots 42 in the rings 36. The sealing rings 36 are also prevented from rotation by at least one bolt 48 screwed into the wall 15 and passing through one of the members 46 into engagement with recesses 50 in the rings. The inside surfaces 76, 78 of the wall 13 and cover 20 may be coated with a non-corrosive material, such as copper, brass, stainless steel, rubber or synthetic plastic. Cooling water may be fed to the sealing faces through a channel formed in at least one of the bolts 48 and through bores 54 in the member 26. The casing 12 may be divided into four radially separated parts corrected by bolts 18 passing through flanges 19, and in order to facilitate the installation of the member 26, which is relatively heavy, the latter may be provided with threaded holes 68 for the reception of eye bolts.

Abstract: 928,078. Liquid-pressure engines. T. H. PARIS Inc. Nov. 21, 1960 [Nov. 23, 1959], No. 39894/60. Class 69 (2). A distributing valve for an hydraulic engine comprises a pilot spool 10 which, in the position shown, directs liquid 45 through a port 47, an annulus 21 and passages 49, 50 to the end face 32 of a movable piston 30, located between plungers 33, 34, such that when the plunger 33 enters a cavity 36 it generates a higher pressure than the primary pressure on the spool 10 and, through passages 38, 53 and pilot end chamber 39, causes the spool 10 to move to the right-hand position, so that the primary pressure is applied through passages 54, 55, 59, 58 to the opposite face 31 of the piston, and also through open check valve 64 and passage 53 to maintain the spool in the right-hand position. Initially, primary pressure is also exerted against the right end of the spool 10 by liquid which flows past a check valve 51 and through passage 52, and against the left end of a main spool 22 by the liquid in passages 54, 55, 56 and end chamber 57 so that the spool 22 is urged to the right. As the pilot spool 10 is moved to the right, annuli 21 and 20 are interconnected, and primary pressure is applied through passage 65 to the right-hand end of the main spool 22 urging it to the left. Plungers 70, 71 are manually operated to assist in purging air from the system by reciprocating the spool 10 during the initial start-up. In a modification, a plug 74 is removed, the passage 54 is blocked, and a different volume rate of liquid pressure is applied at a port 75 than is applied at the port 47, to operate the piston 30 at different speeds in opposite directions, or at the same speed when the piston loads in opposite directions are different.

Abstract: 1, 097,442. Rotary fluid-actuated motors and pumps. F. N. R. D. Ltd. Oct. 7, 1964 [Oct. 11, 1963], No. 40249/63. Heading F1F. A multiplex fluid-actuated rotary motor, or pump, includes a plurality of pairs of abutment rings or stators 3, 3', 5, 5', 7, 7', Fig. 1, and corresponding pairs of rotors 2, 2', 4, 4', 6, 6' on a common shaft 1, the stators in each pair being separated from each other by a spacing piece 8, 11 or 12 whereas adjacent pairs of stators are separated from each other by outlet manifolds 10 or 14 and are clamped together between inlet manifolds 9, 13 for the outer pairs of stators. Pairs of inlet and outlet ports 16, 19, Fig. 3, for working-fluid in each stator are situated on either side of an outwardly-sliding radial-vane 18, the outlet ports 19 being connected to the adjacent outlet manifold by axially-aligned ducts 22, (23), Fig. 2 (not shown), in the stator and the associated spacing-piece, respectively. The inlet ports 16 in the outer pairs of stators 3, 3', 7, 7' are connected to the manifolds 9, 13, respectively, by axially-aligned ducts in their side walls and the associated spacing-pieces, the ports 16 in the inner pairs of stators 5, 5' being connected to an inlet manifold (not shown) by a plurality of pipes 15, so that the pairs of stators and the corresponding rotors can be individually operated to meet varying load conditions. The vanes are biased towards the associated rotors by springs 37, (38) acting upon rockers 11 and by fluidpressure communicated from their high-pressure sides to their radially outermost edges through clearance spaces between the vanes and the sides of the grooves in which the vanes are lodged, a suitable space being provided at the radiallyoutermost part of each slot, as shown in Fig. 3. When one pair of stators and the rotors associated therewith are operating idly said space in the slot for each vane may be vented to the atmosphere through a pipe 41 while the corresponding outlet manifold is closed to effect retraction of the vanes against the action of the springs 37, (38). Alternatively, the corresponding outlet manifold is pressurized by external pressurizing means (not shown) so as to retract the vanes, the pipes 41 being vented to the atmosphere while the supply of working-fluid is cut off. The outputs of the pairs of associated stators and rotors may differ from one another when the motor or pump comprises only two pairs of stators. The said two pairs of stators may be hydraulically connected either singly or in parallel with each other. Each stator is surrounded by a stationary ring 30 or 30' so as to define an annular space that is filled with fluid as described in Specification 1,093,486.
