Abstract: An accumulator piston (10) for an automatic transmission (12). The piston (10) comprises two components, the first and second being cup elements (32 and 36) welded together with their closed ends in abutting relation. The lower cup (32) includes a curled back portion with a radial flange having an axially extending bi-directional oil seal (34) thereon, and spaced apart recesses in the curled back portion to permit oil to flow therein. The upper cup (36) includes a radial flange of reduced diameter compared to the lower cup flange. The flange also has a lip seal (40) thereon. The piston (10) is spring-loaded and moves up and down in a pair of opposed bores (46 and 72) in response to fluid flow on either side to absorb shifting shocks.

Abstract: A pressure vessel (10) has partially telescoped upper and lower shells (12, 14), a diaphragm (20a) with a peripheral edge (26) trapped and sealed between the shells (12, 14), and compression structure (50, 52) on the inner side (44a) of the peripheral edge (26) of the diaphragm (20a) reducing the amount of diaphragm material requiring compression and also increasing the compression of the bulge (42) of the peripheral edge (26) of the diaphragm (20a) in the bulge (34) of the upper wall section (18) of the lower shell (14) to enhance the seal thereat. The compression structure includes one or more internal ribs (50, 52) on the inner side (44a) of the peripheral edge (26) of the diaphragm (20a) such that the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) compresses the internal ribs (50, 52) and subjects the bulge (42) of the peripheral edge (26) of the diaphragm (20a) to a direct force to provide the noted increased compression of the bulge (42) of the peripheral edge (26) of the diaphragm (20a), and such that the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) engages and compresses the first rib (50) to apply a radial outward force compressing the peripheral edge (26) of the diaphragm (44a) radially outwardly against a tapered wall portion (54) of the upper wall section (18) of the lower shell (14) which also compresses the peripheral edge (26) of the diaphragm (44a) downwardly into the widest radial area portion of the bulge (34) of the upper wall section (18) of the lower shell (14) to enhance the seal thereat, all while still maintaining ease of telescoped assembly of the shells (12, 14), and such that the radial force on the ribs (50, 52) from the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) is allowed to spread the ribs (50, 52) axially into less compressed areas (74, 82) to enable the noted reduction in the amount of diaphragm material requiring compression.

Abstract: The present invention is directed to a dependable, low cost, low pressure accumulator characterized by the provision of a bladder support subassembly secured to an end cap member by an annular weld line, the connection between the noted components being effected prior to insertion of the assembly and end cap into a cylindrical pressure vessel component, whereby the opposed surfaces in registry with the weld are exposed to ambient temperatures, eliminating the danger of damage to the bladder in the course of welding. The bladder subassembly and end cap are thereafter inserted into and weldingly connected to a pressure vessel, the open mouth portion of which is inwardly deformed to overlie the end cap and retainer portion of the bladder subassembly, dependably to secure the components together and to effect the desired seals between adjacent components. The invention is further directed to the method of forming the described vessel.

Abstract: A pressure accumulator and method of forming the same is disclosed which comprises the steps of advancing a cylindrical resilient metallic sleeve carrying a separator or bladder through the open mouth of a shell forming a part of the casing of the accumulator, the shell including on an inner wall surface thereof an annular groove defining an inwardly directed sharpened lip in the casing wall. The sleeve is positioned such that the outer circumference thereof, adjacent its upper end, is disposed in abutting relation to the said lip. An electrode is placed against the upper edge of the sleeve opposite the lip at a position remote from the deformable bladder. The shell section and the electrode are relatively rotated about an axis of revolution coincident with the longitudinal axis of the shell while electrical current is passed through the electrode, sleeve, and into the casing, the current flow being sufficient to induce a melting and consequent fusion between components of the metal forming the sleeve and lip portion, whereby the sleeve is secured to the shell section and a seal is defined by the annular fused portions of the shell and the sleeve. Thereafter the open mouth portions of the shells are welded together to define a completed casing.
