Abstract: In order to provide an accumulator equipped with an emergency safety mechanism that is capable of being activated at a lower pressure than when a rupture disk is disposed on part of the circumference of the peripheral surface of a stay, the accumulator has an emergency safety mechanism that immediately releases pressure inside a housing to an oil port side when the inside of the housing reaches a high temperature and high pressure in an emergency such as a fire. The emergency safety mechanism allows a fluid chamber and the oil port to communicate via a first pressure release flow passage, which is formed due to a seal holder provided with recesses and projections on part of the circumference being seated on a seating surface, and a second pressure release flow passage formed due to a rubber-like elastic body of the seal disappearing as a result of the high temperature.

Abstract: An accumulator of the invention is provided with a safety mechanism for an emergency which releases an internal pressure of the housing to the oil port side so as to prevent the housing from being exploded by the internal pressure of the housing which comes to a higher pressure in an emergency, for example, occurrence of fire disaster. The safety mechanism for the emergency has a taper portion in a corner portion between the tubular portion and the end surface portion of the stay. The taper portion is buckled at its root position in the emergency. In the case that the taper portion is buckled, a pressure releasing flow path is formed between the bellows cap or the retained member and the taper portion as well as the bellows cap or the retained member and the end surface portion come away. The stay can be manufactured only by press molding.

The accumulator is characterized in that the bellows (19), on the end of the bellows (29) opposite the mobile terminal element (35), is immobilized on a retaining ring (25) which is fixed to the housing, the end of the sleeve part (63) abutting on said end. The guiding means comprises an annular element (47) an annular part (49) thereof forming the first annular section (51) engaging in a peripheral groove (45) on the terminal element (35). The annular groove is positioned axially off-set on the terminal element (35) away from the immobile bellows end (29) in the direction increasing the distance to the retaining ring (25).

Abstract: A piston-in-sleeve accumulator includes a cleaning element positioned on the piston and configured to remove and prevent debris from lodging between the piston and a cylindrical nonpermeable sleeve within which the piston slides. A seal on the piston is positioned to engage an opposing surface in the event of a leak, and thereby prevent the possibility of a complete drainage of pressurized fluid from occurring through the accumulator's fluid port. A position contactor switch is further provided to signal position of the piston within the accumulator.

Abstract: A piston-type accumulator includes a separating piston (24) axially displaced inside an accumulator housing (10) and separating two spaces from one another inside the accumulator housing (10), particularly a gas side (22) from a liquid side (20) of the accumulator. Due to the fact that the separating piston (24) is predominantly or completely made of a plastic material, it can be provided with a very light weight reducing the overall installation weight of the piston-type accumulator.

Abstract: A pressure container has a steel pipe and an end plate that is formed with a joint portion by allowing its tapered surface to touch a tapered surface of an opening end of the steel pipe so as to block the opening end. The steel pipe has a flange portion which can be cut at the opening end of the steel pipe, and the joint portion is allowed to touch the flange portion. The flange portion is pressed against the opening end along an axial direction so as to touch the end plate, and while the end plate is being pressed against the steel pipe along the axial direction, an electric current is applied so that welding is carried out.

Abstract: A hydraulic accumulator includes a piston (3) capable of moving in an accumulator housing (1) in its axial direction and separating a gas side (5) from a liquid side (7) of the accumulator housing (1). Guide elements (9, 17) designed to co-operate with the accumulator housing wall (1), as well as at least one sealing element (15), are arranged at the periphery of the piston. The sealing element is arranged offset in the axial direction relative to the guide elements (9, 17), and is located between the guide elements. In the piston (3), a pressure compensating channel (19) forms, at the piston periphery, a liquid flow path between the liquid side (7) and a space (2) located between the guide element (17) nearest to the liquid side (7) and the sealing element immediately next in the axial direction. A device (25) reducing the cross-section of the passage of the pressure compensating channel (19) is located in it.
