Abstract (en)
[origin: EP0869285A2] The regulator is for a hydraulic pump (2), feeding at feed pressure into a working conduit (5) with built-in measuring throttle (6). A scavenging circuit (30,38,40,39) branches off the working conduit upstream of the throttle, to scavenge the inner housing chamber of the pump. The circuit has a scavenging valve (30) connected to a load pressure record line (7). The valve interrupts the scavenging circuit, when the pressure in the load pressure record line exceeds a set first threshold value. When a load pressure is below the set first threshold, the scavenging valve throttles the flow through the scavenging circuit with increasing load pressure.
