Regulator for variable vane cell pump for use in vehicle power steering systems, has pressure limiting for pressure side supply connection integrated into pump actuator control to reduced transport quantity depending on limiting pressure

摘要

The regulating device has a pump actuator (3) with a flow regulating valve with connections on both sides of a stop for pressure-limited pressure-side supply connection (16) of the pump to a load. The pressure limiting for the pressure side supply connection is integrated into the control arrangement for the pump actuator so that the transport quantity of the pump (1) is reduced depending on the limiting pressure.
