Abstract: A piston accumulator having a piston-poppet assembly to equalize substantially the liquid-gas pressure appearing across a piston seal. The assembly projects into the hydraulic chamber from its housed position within a socket recess formed in the piston. In response to an excess pressure differential between the gas chamber and liquid chamber of the accumulator, the assembly prematurely seals off the hydraulic passage which communicates with the hydraulic chamber of the accumulator. This premature sealing operation traps and pressurizes a small portion of hydraulic liquid within the reduced hydraulic chamber so that the pressure differential which would otherwise appear across the piston seal is reduced or eliminated.

Abstract: A sleeve-type bladder accumulator having an outer generally cylindrical body, an apertured cylindrical stop tube concentrically disposed within the cylindrical body, an elastic tubular bladder sleeve partially enveloping the stop tube with each end of the sleeve being anchored by sandwiching between a bladder retainer carried on the adjacent end of the stop tube and the end cap fixed to the adjacent end of the cylindrical body, a clamping spring nested within the bore of one end of the stop tube and a spring socket formed by the adjacent bladder retainer to exert a force upon the stop tube tending to move the stop tube away from the adjacent bladder retainer to secure a pair of split shear rings which lock each end of the cylindrical body to its adjacent end cap, and sealing means made more secure by the force generated by the clamping spring.

Abstract: An accumulator having a housing, a spring-loaded liquid inlet-outlet valve, a gas charging and release valve, and a gas-liquid separator in which a top is provided releasably connected to the housing for servicing the accumulator from the top. The top is slidably insertable into the top of the housing and a releasable lock is positioned externally of the top for locking the top in the housing. The lock is prevented from releasing while the top is held in an upward position by pressure in the housing and can only be released when the pressure in the housing is reduced and the top is moved downwardly. The locking means includes a notch in the exterior of the housing, a locking ring, and a backup shoulder on the exterior of the top. An anti-extrusion ring is bonded on the bottom edge of the top and slidably engages the interior of the housing for preventing damage to the separator. Preferably the top includes a dome and an annular flange extending around the lower end of the dome. The liquid inlet-outlet valve is a poppet valve in which the valve element is enclosed by a resilient coating with an annular resilient ring bonded to the coating and positioned to seat on the valve seat. The separator may be a bag separator or a cylindrical solid float having a tapered bottom with a plurality of axially extending recesses about its outer periphery for preventing the float from sticking on the interior of the housing.

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 pressure vessel having a housing subdivided by a flexible partition into an upper gas portion and a lower liquid portion. The gas portion of the housing forms a gas chamber surrounding by an upper wall formed of curved lines of various radius. An inlet to receive a pressure gas is formed in the upper wall so that the inlet is positioned in the area of the upper wall outlined with a curve of a minimal radius. After loading of the pressure vessel with a gas under relatively high pressure the inlet is sealed by a locking element. In the area where the inlet with the locking element is positioned, the deformations exerted on the wall under gas pressure are minimal.

Abstract: A hydropneumatic assembly particularly for use as a pressure reservoir in a shock absorber includes a housing with a diaphragm operatively mounted within the housing to define therein a liquid chamber on one side of the diaphragm and a gas chamber on the opposite side thereof. The liquid chamber is defined between an inner wall of the housing and the diaphragm and the diaphragm is arranged to be pressed against the inner wall under the influence of gas pressure within the gas chamber. Damping liquid for a shock absorber flows into and out of the liquid chamber to an opening provided in the inner wall of the housing and, by a special feature of the assembly, ducts are defined between the inner wall of the housing and the diaphragm, with the ducts being directed to extend toward the opening through which liquid flows into and out of the liquid chamber.
