  • Pressure fluid actuated device
    Publication number: 20030007868
    Abstract: The invention relates to a hydraulic fluid actuator configuration with a working piston (2) that is guided in an actuating cylinder (4), with this piston being supplied pressure on both sides. In order to prevent an excursion of the working piston (2) from its neutral position (x=0) due to leakage, a hydraulic fluid displacement device (20) is suggested, which supplies a control volume over a period of a harmonic movement of the working piston (2) to the side of the working piston (2) to which it traveled.
