Pulsation damper for axial piston of hydrostatic regenerative braking system, has radial feeder including movable piston that is arranged in straight pipe radial feeder attached to high pressure connection of axial piston

摘要

The damper (1) has a radial feeder (7) tuned on various resonance wavelengths and includes a movable piston (9) that is arranged in a straight pipe (8). The piston sets the radial feeder in an operating length corresponding to the resonance wavelengths of a pulsation axle of an axial piston (4). The radial feeder is attached to a high pressure connection (10) of the axial piston, and the movable piston is axially moved in the pipe of the radial feeder using hydraulic pressure. The radial feeder includes a threaded bar that is axially arranged in the pipe. Independent claims are also included for the following: (1) a regulating arrangement for damping a pulsation sound wave, comprising a speed sensor (2) a method for absorbing a sound of an axial piston using a pulsation damper.
