Abstract: An acoustic filter adapted to be fitted on a pipe for the purpose of absorbing pressure waves. The acoustic filter has a body constituted by a cylinder, an inlet and outlet end, a locking ring fitted in a groove located at the inlet and outlet ends, coupling means within the locking rings for coupling the filter to a pipe. A holder tube fitted with diffuser rings for connecting the coupling means. A deformable bag made from a flexible material is mounted between the inlet and outlet ends, shaped like a cylindrical sleeve and surrounds the holder tube and diffuser rings. The bag defines with an inner wall of the cylinder a chamber for receiving a pressurized gas.

Abstract: A temperature responsive fusible packing is inserted in a ring shaped space defined between the lower face of a bolt head and the bottom face of a recessed portion formed on the supply port of a gas chamber of an accumulator and then the bolt is tightened, so that the fusible packing can act as a packing which blocks both the gas passage and the inner passage formed through the shank of the bolt. In the event where, the temperature responsive fusible packing should melt due to a fire or the like, since the thus fused packing is expelled outside the device through a gap formed between the wall face of the recessed portion and the outer periphery of the bolt head, a vacant space would be formed there to expose the inner passage to an open air and allows the gas in the gas chamber to be discharged outside.

Abstract: A gas-pressurized collapsible bladder inside a fluid accumulator in a hydraulic system has a detection device that informs a user about the state of inflation of the bladder. Abnormalities in system operation, e.g., a gas leak from the collapsible bladder or sudden turning on of the fluid-actuated device in the system can cause bladder deflation whereas clogging of lines or sudden stoppage of a fluid-actuated device may cause fluid pressure rise in the system, and hence, deflation of the collapsible bladder to actuate the detection device. In one aspect of the invention, the condition of the bladder is detected by use of a permanent magnet that actuates a reed relay. In another aspect of the invention, a light-emitting diode, a reflector and a photosensor detect the bladder condition.

Abstract: A pressure accumulator for hydraulic systems in control mechanisms of eleic high-voltage lines comprises essentially a cylinder which is closable at its end faces by a lid, wherein the lid includes a cover plate inserted in the cylinder and having a shape such as to define an annular recess at its periphery in which a cover member is located thereby defining an annular groove between the cover plate and the cover member. Within this annular groove, a sealing member is disposed having the shape of an annular disk. For preventing penetration of the edges of the sealing ring into gaps formed between the individual lid parts and the cylinder wall, the cover member, the cover ring and the sealing ring are provided with associated recesses and grooves in which respective support rings are disposed.

Abstract: A split tank closure and diaphragm assembly for a hydropneumatic filament wound pressure vessel is disclosed. The assembly includes first and second cup shaped plastic tank liners having oblate ellipsoidal end portions and cylindrical sidewall portions terminating in cylindrical open mouth portions. A ring is provided for joining and sealing the open mouth portions together to form a sealed container and to mount a diaphragm within the tank to divide the interior of the tank into variable volume chambers. The ring has a cylindrical outer surface corresponding to the outside diameter of the cylindrical sidewall portions of the liners. The liners form a dovetail joint with the ring and respectively trap an O-ring and a bulbous portion of the diaphragm between recessed portions of the liner and a surface of the ring to seal the interior of the tank. The assembly is wound with a resin impregnated continuous roving to reinforce the tank and resist internal pressures.

Abstract: A hydraulic conduit and a pressure vessel having an interior chamber provided with an opening cooperate with one another. A flexible partition subdivides the chamber into a first compartment which communicates with the opening, and a second compartment which contains a body of compressed gas which normally flexes the partition wall into the first compartment and against the opening. Connecting passages are provided which so connect the hydraulic conduit with the opening that hydraulic fluid flowing in the conduit is conducted in its entirety through the first compartment at least at such times as the flexible partition is out of contact with the opening.

Abstract: The accumulator disclosed herein has a spring, which consists of two or more concentric steel cylinders with at least one cylinder sleeve of neoprene between them. The contact surfaces of the steel and the neoprene are bonded together and have a shear strength equal to the shear strength of the neoprene itself. The inner cylinder is connected to a piston rod and the outer cover encloses the assembly. The length of the space is such that sufficient preload is placed on the assembly to hold the parts together, even under shock conditions. A manifold connecting a relief valve and a check valve with the appropriate passages and porting is attached to the side of the cylinder, permitting the passage of oil into and out of both ends of the cylinder.
