Abstract: A method is disclosed for monitoring a pressure fluid reservoir that is equipped with an elastically-shaped media-separating element and a terminal position seal in which fluid reservoir is connected in a pressure fluid loop having a pressure generator driven by a drive unit and having at least one measuring instrument, which detects a parameter representing the operating pressure in the pressure fluid loop. The parameter is delivered to an electronic control unit, where it is further processed into a trigger signal, among others for the drive unit of the pressure generator. After the operating pressure in the pressure fluid loop has dropped below a prestressing pressure the drive unit of the pressure generator is triggered by the control unit, and via a predeterminable time interval beginning with this triggering, the signal course of the measuring instrument is plotted by the control unit and compared with a suitably memorized set-point value course. Deviations in the signal course in the positive direction allow conclusions to be drawn about possible damage in the pressure fluid reservoir, particularly at the terminal position seal.

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: A shell is constituted by an outer shell and an end plate. The end plate has a port in communication with a liquid chamber. A bladder divides an internal space of the shell into a liquid chamber and a gas chamber. A gas is introduced into the gas chamber without the provision of a gas inlet hole in the outer shell located on the side of the gas chamber. For example, an accumulator is assembled by combining the outer shell, the end plate and bladder under atmosphere of a high pressure gas.
