Abstract: An accumulator has a piston axially slidably disposed in a cylinder mounted in a casing, the cylinder and the piston jointly defining a reservoir communicating with an inlet/outlet port in the casing. A piston rod axially movably disposed in the casing has an end slidably fitted in the cylindrical hole of the piston. The piston rod is normally urged by a spring to force the piston into the reservoir. The accumulator also includes a switch mechanism for detecting the position of the piston in the cylinder. The switch mechanism may comprise a reed switch, a light-sensitive switch, a pressure-sensitive switch, or a pushbutton switch.

Abstract: Method of manufacturing an accumulator device including a shell portion having an open mouth and a cap member affixed over the open mouth after a bladder assembly has been secured within the shell portion of the pressure vessel. The method comprises in the provision of an exterior annular weld connecting the cap member to the outer wall portion of the vessel as well as an interior weld connection between the interior wall portion of the cap member and the upwardly directed end edge of the mouth of the pressure vessel. By locating the metallic skirt member which functions to support the bladder such that the top of the skirt forms a dam for containing the weld which secures the cap member interior to the uppermost edge of the pressure vessel, the possibility of weld fragments falling into the bladder causing damage to the latter is minimized.

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: 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 compensator for use with a hydraulic control valve connected to a source of high fluid pressure provides the functions of a low pressure return line accumulator and controllable check valve. A spring loaded piston (66) in a housing (64) has a working face exposed to fluid pressure downstream of the power control unit (10). A poppet valve (80) movable in a bore (78) on the axis of the piston is spring loaded against a seat (82) in the return line (40, 42) to interrupt flow between the downstream side of the power control unit (10) and the return side of the fluid pressure source. When normal return line pressure is sensed, the piston (66) moves against its spring (68) to permit the housing (64) to be substantially filled with fluid. Further increases in fluid pressure cause the piston (66) to contact and open the poppet (80) and permit flow to the return side (42) of the fluid pressure source. A working area (92) is formed on a part of the poppet (80) to the outside of the seat which area is exposed to the fluid pressure downstream of the power control unit (10). Should the piston (66) stick or seize in the housing (64), the fluid pressure acting against this working area (92) would increase to some value significantly above the normal pressure at which point it becomes sufficient to open the poppet (80), thus preventing the power control unit (10) from jamming or becoming hydraulically locked in position.

Abstract: The invention relates to a fluid supply system and seeks to provide a simpler, safer but reliable system than at present known. The fluid supply system comprises a multi-charge solid propellant gas generator and a fluid expulsion unit integrated into a single unit, the gas generator being provided in a cap (8) for a chamber (1) having a gas portion (3) and a fluid portion (2) and a movable partition (4) between these two portions operable to expel fluid from the chamber when the gas generator is rendered operative. The system also comprises ignition control means (22) operable to control the ignition of the solid propellant charges (13) when required to give a fully controllable system output.The system can be designed for supplying under pressure fluids such as hydraulic oil, fuels, oxidants and water and is particularly useful in aerospace applications.
