Abstract: In a hydraulic system which is biased to a minimum system pressure using a bias valve or other flow obstruction disposed in a tank line, there is provided in a bypass line to the bias valve an evacuating and filling valve through which the hydraulic system is first evacuatable and subsequently fillable with a hydraulic fluid. The valve closes the bypass when a differential pressure overcomes a preadjusted force of a spring element. For this purpose, the valve possesses a displaceably mounted valve body with an integrated throttle and a seal face which closes a through opening when the valve body is shifted against the bias force of the spring element due to the pressure difference.

Abstract: A piston accumulator (10) comprises a pressure chamber (40) which on one side is closed by a piston (50) axially displaceable in a pipe (20) in order to change its volume depending on the axial position of the piston (50). A detent mechanism is provided in order to hold back the piston (50) against a spring preload (190) in a second position differing from a first position. The piston (50) is formed in a multi-part fashion and comprises at least a first piston part (52) and a second piston part (54), wherein at least one of the two piston parts (52) is hardened and disposed to cooperate with the detent mechanism in a catching fashion.

Abstract: A piston accumulator (10) comprises a pressure chamber (40) which is closed on one side by an axially shiftable piston (50) in order to change its volume depending on the axial position of the piston (50). A locking mechanism is provided for retaining the piston (50) in a second position different from a first position against a spring preload (190). The piston accumulator (10) further comprises an electromagnetic apparatus (80) having an armature (150) which is shifted upon axial shifting of the piston (50) from the first into the second position in its turn into an axial position in which a blocking element (175) of the locking mechanism is held by the armature (150) in a radial position so as to block a shift of the piston (50) back in the direction of its first position. For holding the blocking element (175) there is provided a separate interlocking member (170) which is fastened to the armature (150) and is made of a harder material than the armature (150).

Abstract: A sieve filter for fluid lines, especially for hydraulic pressure lines (2) in internal combustion engines which is formed of a hollow cylindrical main body (3) with a fluid inlet (4) and a fluid outlet (5), and of a fine mesh filter element (6) for through flow by fluid which has a bypass function when the filter element (6) is stopped up or filtering highly viscous fluid. The sieve filter (1) is biased by a spring element (7), and is insertable together with the spring element (7), between two axially spaced opposing surfaces (8, 9) inside the pressure line (2) such that its fluid inlet (4) and the spring element (7) are prestressed against the opposing surfaces (8, 9), whereby the main body (3) of the sieve filter (1) closes a bypass fluid channel passing the filter element (6) which is clearable through an axial displacement of the main body (3) against the force of the spring element (7) resulting from the rise of fluid pressure on the filter element.
