STEUERVORRICHTUNG FUER EIN HYDROSTATISCHES GETRIEBE FUER WENIGSTENS ZWEI VERBRAUCHER.

摘要

The load sensing control device monitors the feed flow for each load by a pressure balance (15) associated with a control valve (7) in the hydraulic line (3) supplying the load. The setting adjustment (9) for the hydrostatic pump (2) is adapted to obtain a feed rate which is less than the sum of the momentary volumetric flows for the two loads. Pref. the setting adjustment uses an electrohydraulic proportional valve with the control valves (7) incorporated in the hydraulic lines (3) pref. comprising further electrohydraulic proportional valves.
