Drive with an energy recovery function having a brake pressure control valve

摘要

Drive comprises a hydrostatic piston machine (9) connected to a storage element (13) and a throttle valve unit (15) which divides a storage line into a first storage line section (11) and a second storage line section (12). The throttle valve unit comprises a control pressure valve unit (16) and a built-in valve (17). A control pressure produced by the control pressure valve unit acts on the built-in valve. Preferred Features: The built-in valve is impinged with a control pressure on a control pressure surface and with a conveying pressure and storage pressure in the opposing direction.
