Abstract: A hydraulic accumulator, especially a bladder accumulator, includes an accumulator housing (10), and a separation element disposed in and separating the accumulator housing interior into a gas chamber (16) adjoining an inlet (14) on the gas side from a fluid chamber (18) adjoining an inlet (20) on the fluid side. The inlet on the fluid side has a fluid connecting neck (22) having a valve support (40) disposed in the neck. The valve support has fluid openings (42), and a disk-shaped valve body (32) that tapers towards the valve shaft (46) on its side facing the valve support (40). The valve shaft can be pretensioned via a force accumulator (62) into the open position releasing the fluid opening, can be displaced into its closed position by a displacement of the separation element (12), and projects into the fluid chamber (18) in the open position. The valve body (32) is an integral, especially one-piece, component of the valve support (40) that is guided along its outer periphery (56) within the connecting neck (22) so as to be displaceable in it, creating a hydraulic accumulator that is comparatively simple and inexpensive in production.

Abstract: A bellows-type hydraulic accumulator includes a shell, a bellows unit, and a stay in order to accumulate pressurized liquid within a liquid chamber, divided into a fixed-volume liquid chamber and a variable-volume liquid chamber communicating with the fixed-volume liquid chamber via a communication port formed in the stay. A pipe is inserted into a liquid inlet/outlet port communicating with the fixed-volume liquid chamber, to thereby form an inflow passage inside the pipe and an outflow passage outside the pipe. A tip end of the pipe is located within the communication port of the stay with a predetermined radial clearance formed between the tip end and a wall surface of the communication port, to thereby enable pressurized liquid to be supplied to the variable-volume liquid chamber from the tip end of the pipe and to be discharged from the variable-volume liquid chamber to the fixed-volume liquid chamber via the radial clearance.

Abstract: In a metal bellows accumulator, a metallic bellows unit is disposed within a pressure space defined in a main shell, and one end of the metallic bellows unit is fixedly secured to one end wall of the main shell. The metallic bellows unit sections the pressure space into an outer chamber serving as a gas chamber in which a pressurized gas is enclosed, and an inner chamber serving as a liquid chamber communicating with a liquid port formed in the end wall of the main shell. A stopper (auxiliary shell) for limiting collapsing movement of the metallic bellows unit is disposed within the liquid chamber and has a communication passage hole. The liquid port always communicates with a liquid chamber to which an inner circumferential surface of a bellows portion of the metallic bellows unit is exposed via the communication passage hole.

Abstract: A fluid storage and expulsion system comprising a tank 12 with an internal flexible diaphragm assembly of dual diaphragms 17,18 in back-to-back relationship, at least one of which is provided with a patterned surface having fine edges such that the diaphragms are in contact along said edges without mating contact of surface areas to thereby form fluid channels 27 which extend outwardly to the peripheral edges of the diaphragms. The interior wall of the tank at the juncture of tank sections 14,15 is formed with a circumferential annular recess comprising an outer annular recess portion which forms a fluid collection chamber 40 and an inner annular recess portion which accommodates the peripheral edge portions of the diaphragms and a sealing ring 38 in clamped sealing relation therebetween. The sealing ring is perforated with radially extending passages 39 which allow any fluid leaking or diffusing past a diaphragm to flow through the fluid channels 27 between the diaphragms to the fluid collection chamber. Ports 21,23, connectable to pressure fittings are provided in the tank sections for admission of fluids to opposite sides of the diaphragm assembly. A drain passage 42 through the tank wall to the fluid collection chamber permits detection, analysis and removal of fluids in the collection chamber.

Abstract: In the interior of the housing of an accumulator, a metallic bellows and a self-seal mechanism are arranged. The metallic bellows partitions the interior of the housing into a gas chamber and a liquid chamber. The self-seal mechanism includes an elastic seal member and a face which the elastic seal member opposes. When the bellows is compressed to the predetermined extent due to introduction of a compressed gas into the gas chamber, the elastic seal member is brought into contact with the face, thus closing a flow port. The elastic seal member has a slanted face, so that a wedge-shaped liquid guide gap is produced when the elastic seal member is in contact with the face. When, in this condition, the compressed liquid is introduced into the flow port, part of the liquid enters the liquid guide gap, thus permitting the seal member to easily separate from the face.
