Abstract: The invention relates to a method of using new flushing ports (1A, 1B) when cleaning a piston accumulator (7). Dirty hydraulic oil is returned out via the main port (2) and a return passage (9) until a cleanness grade has been reached. Clean hydraulic oil is forced into the piston accumulator (7) via the axial bores (3A, B) of the flushing ports (1A, B) and further in sloping bores (3C, D), bringing the hydraulic oil into the volume (8) in an upward, tangential direction below the piston (5), into a flushing circulation. By reducing the gas pressure on the gas side (4) of the piston (5) in relation to flushing pressure input from a valve (6), a volume (8) is created on the oil side between the piston (5) and the end bottom (3). The return passage (9) is closed and the piston (5) is brought into its upper position, so that an internal cylinder wall (10) is cleaned. Upon pressure build-up, the return passage (9) is opened, and the piston (5) returns to its end position on the oil side while the supply of clean hydraulic oil is maintained, and the operation is repeated until a clean-ness grade has been achieved.

In order to achieve an optimised damping of the discharge pulsations, the adjusting means are according to the invention arranged for determining the desired gas pressure characteristic in the damping chamber on the basis of the discharge characteristic of the displacement pump and determining the current gas pressure characteristic in the damping chamber, and comparing the current gas pressure characteristic as determined with the desired gas pressure characteristic of the damping chamber and determining the current position of the interface layer in the damping chamber on the basis of said comparison.

Abstract: A braking system includes an accumulator positioned along the brake line between the wheel brake and a pump. The accumulator includes a cylinder defining a bore and a piston fitted within the bore. The cylinder defines an inlet and an outlet fluidically connecting the bore to the brake line. The outlet is axially spaced from the inlet and is positioned to be sealed closed by the piston when it is proximate to inlet. The accumulator stores a reserved volume of fluid that is not delivered to the pump via the outlet to thereby reduce the volume of fluid delivered to the master cylinder by the pump and prevent damage to the lip seals during ABS control.

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 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: 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.
