Hydrostatic drive system has pressure valve actuated in direction of minimal setting pressure in drive phase and towards maximum setting pressure in braking phase and/or rest position

摘要

The system has a pump (2) driven by a drive motor (1) and at least one load (5a,5b) connected to the pump. A pressure valve (10a,10b) with variable setting pressure is used to generate a pressure for braking the load. The valve is actuated in the direction of minimal setting pressure in the drive phase and towards maximum setting pressure in a braking phase and/or a rest position.
