Abstract:
A device for controlling a hydrostatic drive comprising a resonator having a periodically actuatable switch valve which connects the resonator alternately with a pressurized-fluid supply line a return line and the hydrostatic drive, wherein the resonator (2) has at least one pressure chamber (6) with a movable, oscillatable chamber limitation (7) for changing the chamber volume; the movable chamber limitation (7) forms a part of a single-mass oscillator comprising mass and spring (10), and the pressure chamber (6) which is connectable alternately to the pressurized-fluid supply line (4), the return line (5), and the hydrostatic drive (1) via the switch valve (3) with a switch frequency which lies within the supraresonance region of the single-mass oscillator.
