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: 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: A hydraulic fluid reservoir comprises a body defining a variable volume chamber having one end portion movable with the level of fluid in the chamber. A biasing member acting on a traction rod extending from the movable end portion restrains movement thereof under fluid pressure. The fluid pressure in the variable volume chamber advantageously counterbalances the force of reaction in the biasing member.

Abstract: In an accumulator comprising a pressure vessel, a bellows dividing the interior of the pressure vessel into a gas chamber filled with pressurized gas and a liquid chamber which communicates with a liquid pressure circuit via a liquid introduction port, a stay member attached to the inner surface of the pressure vessel inside the bellows and provided with a communication port for communicating the interior and exterior of the stay member with each other and adapted to be closed by a part of the bellows to define a fully contracted state of the bellows, and a safety valve provided in the stay member, typically in the form of a weakened portion of the stay member, for selectively communicating the exterior of the stay member with the interior of the stay member. Thus, because the safety valve is not provided in the pressure vessel itself, the safety valve of the present invention would not affect the sealing capability of the pressure vessel.

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 judgment 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: The invention provides a fluid apparatus in which two or more kinds of chemical liquids can be rapidly stirred and mixed in a pump to a uniform concentration. A barrier membrane (7) such as a bellows or a diaphragm that is reciprocally moved in the axial direction is disposed in a pump body (1) so as to form a liquid chamber (9) between the barrier membrane and an inner wall (4a) of the pump body (1). A suction port (18) and a discharge port (19) are disposed in the inner wall (4a) of the pump body (1). Supply pipes (5A) and (5B) respectively for the two or more kinds of chemical liquids are pipe-connected to an inlet portion of the suction port (18) so as to join together. An outlet portion (18a) of the suction port (18) is disposed in a side face of a protruding forward end of a suction check valve (20) which is fixed to protrude from the inner wall (4a) of the pump body (1) into the liquid chamber (9), whereby the outlet portion is opened so as to eject the two or more kinds of chemical liquids toward a circumferential wall (9a) in the liquid chamber (9). Therefore, the two or more kinds of chemical liquids which are separately supplied to the pump body (1) are ejected from the outlet portion (18a) of the suction port (18) so as to circulate along the circumferential wall (9a) of the liquid chamber (9). This circulating action causes the liquids to be stirred and mixed rapidly and uniformly in the liquid chamber (9).

Abstract: A shell is constructed by an outer shell and an end plate. The end plate has a port into a liquid champer and a gas champer. A bladder divides an internal space of the shell into a liquid champer and a gas champer. 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 champer. For example, an accumulator is assembled by combining the outer shell, the end plate and bladder under atmosphere of a high pressure gas.
