Load-sensing regulated hydrostatic drive system for industrial trucks, has pump adjustable in its displacement volume, and supply pressure signal line, which stays in connection with supply side of pump in area of pump by throttle device

摘要

The load-sensing regulated hydrostatic drive system has a pump (1,101), which is adjustable in its displacement volume and a consumer supplied by the pump. The tapping of the supply pressure signal takes place in the area of a control valve (5,105) and the forwarding of the supply pressure signal to a regulating valve device (6,106) of the pump takes place by a supply pressure signal line (52,53,54). The supply pressure signal line stays in connection with the supply side of the pump in the area of the pump by a throttle device (70,170).
