Abstract: The invention relates to a method of using new flushing ports (IA7 IB) 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 (IA, 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 cleanness grade has been achieved.

Abstract: Some embodiments of the present invention provide an accumulator tank assembly and method in which a flexible bladder is received within an accumulator tank. The accumulator tank and the flexible bladder can each have an inlet aperture through which fluid is received within the accumulator tank assembly and an outlet aperture through which fluid exits the accumulator tank assembly. In some embodiments, inlet and outlet flanges positioned adjacent the inlet and outlet apertures of the accumulator tank are used to couple the flexible bladder to internal or external surfaces of the accumulator tank, thereby creating fluid tight seals between the flexible bladder and the accumulator tank.

Abstract: The invention relates to an accumulation chamber for a hydraulic vehicle braking system. According to the invention, the accumulation chamber is configured as a gas separator (32) comprising two connections for fluid located at different heights (36, 38). Wheel braking cylinders of an energy-assisted braking system are connected to the lower fluid connection (38). Said cylinders can be actuated by muscular force, if a service braking system operated by external energy malfunctions. The gas separator (32) keeps gas bubbles away from the lower fluid connection (38), thus preventing gas bubbles from reaching the brake fluid of the energy-assisted braking system operated by muscular force, to guarantee the operation of the latter.

Abstract: A compact hydraulic aggregate for drive slip-regulated braking systems has several hydraulic, mechanical and/or electrically actuated functional elements arranged on a reception body, such as accumulator, valve (1, 1'), pressure generator (5) and driving elements (6), several pressure medium ducts (4, 5, 16) for inteconnecting the functional elements, establishing a hydraulically switchable connection between at least one pressure medium supplier (14) and a pressure medium consumer (19), and a control device connectable by electric conductors to the valve (1, 1') and driving elements (6). The valve elements (1, 1') are arranged in several valve reception bores (2, 2') of the valve reception body (3) which receives a first and a second row of valves (x, y). Between both diametrally opposed rows of valves (x, y) are provided several pressure medium bores (4) for inteconnecting the valve elements (1, 1') and bores (7, 8) for receiving the pressure generator (5) and dribing element (6). Additional co-axially arranged reception bores (9, 10, 11) open into the valve reception body (3) outside both rows of valves (x, y).
