Abstract: A malfunction detection device of a bellows type accumulator for pressurized fluid includes malfunction judgment unit for judging a malfunction of the bellows type accumulator on the basis of a detection output of the pressure sensor. The malfunction judgement unit judges that the malfunction of the seal member generates when the difference between a peak pressure value appeared before a predetermined time is past after the starting of the pressure increase from a value below a predetermined value in the inlet and outlet port and a stable fluid pressure appeared after the appearance of the peak pressure value is not within a predetermined range and/or when the peak pressure value does not appear before the progress of the predetermined time.

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 storage chamber for a hydraulic vehicle brake system is embodied as a gas separator, with two fluid connections disposed at different heights. Wheel brake cylinders of an auxiliary force brake system are connected to the fluid connection located at a low level and can be actuated by muscle force if there is a malfunction of an external-energy service brake system. The gas separator keeps gas bubbles away from the fluid connection located at the low level and thereby prevents gas bubbles from getting into the brake fluid of the muscle force auxiliary brake system, in order to assure the function of that system.

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 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.

Abstract: A piston accumulator for hydraulic actuators, presses or the like is formed with a plunger piston for reciprocating within gas and liquid receiving chambers which are sealed and separated from each other in such an effective manner that compressed air rather than nitrogen may be used in the gas chamber without the danger of ''''dieselization.'''' The plunger piston is guided and sealed by a piston and guiding means intermediate the liquid and gas chamber rather than by usual cylinder bore walls. The expense of machining such internal cylinder bore walls is eliminated as well as the problem of leakage caused by scoring and scratching such machined cylinder bore walls by spacing the chamber walls from the piston plunger wall and using a soft bearing material for the piston sealing and guiding means into which dirt or other material may embed. Means are provided for varying pressure and/or volume of gas to achieve various operating characteristics for the hydraulic press.
