Abstract: An annular tube (or other shape) of elastomeric cellular material comprising elastomeric closed cells having gas infused therein is supported by structures protruding from the bottom surface of a suction stabilizer's head and/or by structures within the interior volume of the annular body of the suction stabilizer, preferably with spacing between the outer diameter of the annular tube of the cellular material and the inner walls of the suction stabilizer body. The gas-infused closed cell material may thus be employed in new suction stabilizer or pulsation dampener or to retrofit existing suction stabilizers or pulsation dampeners designed for a gas-filled bladder.

Abstract: The present invention is directed to the method of making a dependable, low cost, low pressure accumulator characterized by the provision of a bladder support sub-assembly 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 sub-assembly 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 sub-assembly, dependably to secure the components together and to effect the desired seals between adjacent components.

Abstract: A disposable pressure vessel includes a gas valve containing cylindrical cap encircled by an O-ring. The cap is bonded to an annular flared portion of a generally cylindrical rubber bladder and is disposed in a hollow cylindrical housing such that the cap compresses the flanged portion of the bladder against a shoulder in the cylindrical housing. The cap is held in place by three equally circumferentially spaced, lanced portions of the cylindrical housing and the O-ring seals the interior of the cylindrical housing from the exterior.

Abstract: A drop-in signal accumulator piston assembly replaces an original equipment (OE) signal accumulator piston in a vehicle transmission hydraulic circuit. The OE signal accumulator piston is positioned in a bore in a valve body that has an open end and a fluid port. The drop-in signal accumulator piston assembly includes a cylindrical sleeve having open first and second ends, one of the first and second ends defining a reduced diameter region, and a piston positioned in the sleeve. A spring is positioned in part in the piston and in part extending beyond and end of the piston. The sleeve is positioned in the valve body bore, with the piston, and the spring. A method for replacing an original equipment (OE) signal accumulator piston in a transmission hydraulic circuit is also disclosed.

Abstract: A inexpensive pressure vessel which can be disposed of rather than being repaired once it fails, which includes a cylindrical housing having two chambers separated by a resilient bladder. One chamber is for housing a gas while the second is for housing a fluid such as hydraulic oil. The cylindrical housing contains a port at one end and is open at the opposite end. The end cap which contains a through port and a gas valve is insertable into the open end of the cylindrical housing and is welded thereto. This weld joint in conjunction with a seal formed by attaching the resilient bladder to the end cap, will positively seal the pressure vessel. The unique seal between the end cap, bladder and housing is such that it will not be thermally damaged by the welding process which seals the end cap to the cylindrical housing.
