Abstract: A hydraulic circuit includes an accumulator having an inflow passage which introduces a hydraulic fluid which is discharged from a hydraulic pump into a hydraulic fluid chamber and a discharge passage which discharges the hydraulic fluid from the hydraulic fluid chamber to a hydraulic actuator. The hydraulic circuit includes a valve mechanism which restricts the supply of hydraulic fluid from the hydraulic fluid chamber to the hydraulic actuator when the pressure in the hydraulic fluid chamber is less than a set pressure and which releases the restriction of the supply of hydraulic fluid to the hydraulic actuator when the pressure in the hydraulic fluid chamber is at least the set pressure. The valve mechanism may be installed inside the accumulator.

Abstract: A vehicle brake system has a gas pressure accumulator (10) comprising a housing (12), the interior of which is divided by metal bellows (16) into a gas-sensed gas chamber (20) and a fluid chamber (22). Via a feed line (24) a fluid may be supplied under pressure to and removed from the fluid chamber (22), wherein provided between the fluid chamber (22) and the feed line (24) is a valve arrangement (74), which closes when the pressure in the feed line (24) drops below a minimum value and opens when the pressure exceeds the minimum value. To increase the operational reliability of the gas pressure accumulator (10), the valve arrangement (74) closes when the pressure in the feed line (24) exceeds a maximum value and opens when the pressure drops below the maximum value.

Abstract: An ultrasound testing device for gas pressure accumulators is used to test a predeterminable set position that can be taken by a movable separating element inside an accumulator filled with gas and connected to a fluid circuit. The separating element has at least one testing body associated with a visible mark which indicates the set position of the separating element. An ultrasound testing device on a testing body can be set on the accumulator in alignment with the visible mark. This testing device allows a plurality of accumulators of the same type to be tested for their predeterminable gas pressure set value, which corresponds to the gas pre-filling pressure, by a single hand apparatus. This kind of test is economical and achieves reliable results.

Abstract: The pressure-producing device (10) comprises a housing (30) which is slidable relative to a stationary piston (60), the housing (30) movable within a substantially blind bore (12) to effect the pressurization of fluid. A body (14) containing the blind bore (12) includes a retention member (22) located adjacent an end opening (16) of the blind bore (12). The pressure-producing device (10) is received within the blind bore (12) wherein a closed end (32) with a seal (44) thereabout defines with an end of the blind bore (12) a pressurizing chamber (50). The piston (60) is received slidably and sealingly within an interior opening (39) of the housing (30) and extends from an end opening (34) thereof in order to engage the retention member (22) and position stationarily the piston (60). The housing (30) and piston (60) are displaced away from one another by a pressurized medium within the housing (30 ). The piston's (60) stationary position enables the housing (30) to slide within the blind bore (12) and effect the pressurization of fluid received within the chamber (50).

Abstract: The combination accumulator and variable volume sump (50) comprises a housing (52) having therein a stepped bore (56). An H-shaped piston and a U-shaped piston (60, 80) are diaposed within the stepped bore (56), the first piston comprising an accumulator piston (60) and defining with the housing (52) and stepped bore (56) a first chamber (70) containing therein pressurized medium. The second piston (80) defines with the housing (52) and stepped bore (56) a second chamber (90) containing therein pressurized fluid. Open ends of the U-shaped pistons (60, 80) are received one within another, and a spring (95) is disposed between interior openings (62, 82) of pistons (60, 80) to bias them apart. The housing (52) has a pair of openings (54, 59) for communicating pressurized fluid, one opening (54) communicating with the second chamber (90) and the other opening (59) communicating with the stepped bore (56) in order to communicate pressurized fluid to the first piston (60). Displacement of the first piston (60) along the stepped bore (56) results in a corresponding increased displacement of the second piston (80) relative to the housing (52).

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.
