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: The invention relates to a hydraulic accumulator, especially a bladder accumulator, comprising an accumulator housing (10), a separation element disposed therein that separates within the accumulator housing 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. Said inlet on the fluid side has a fluid connecting neck (22) which comprises a valve support (40) disposed in said neck and having 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). Said valve shaft can be pretensioned via a force accumulator (62) into the open position in which it releases the fluid opening, and 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 therein, thereby creating a hydraulic accumulator that is comparatively simple and inexpensive in production.

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.

Abstract: A pressure vessel includes a housing having an interior and a passage communicating with the interior and being bounded by an inner circumferential surface. A separate plug is received in the passage. The plug has an outer circumferential surface juxtaposed with the inner circumferential surface. These surfaces define together at least one gap of relatively small cross-section. The gap extends lengthwise of the passage communicating with the interior of the housing.

Abstract: An upper gas chamber and a lower pressure fluid chamber separated from each other by a diaphragm deflectable in direction of the gas chamber in response to pressure fluid admitted into the lower chamber. The diaphragm comprises a peripheral portion which, by means of an annular element, is sealingly pressed against the inner wall of the reservoir. The annular element has an arcuately curved circumferential guide surface which faces towards the fluid pressure chamber such that upon admittance of a fluid pressure in this latter chamber the center portion of the diaphragm is deflected into the gas chamber whereby the peripheral portion contacts the guide surface of the annular element and is thereby arcuately deformed which avoids acute bending and consequent breaking of the peripheral portion.
