Abstract

A pressure feed system has a first pump (41) permanently loading a pressure accumulator (52) used as a source of pressure for a hydraulic cylinder (11). A second pump (42) feeds a cooling circuit operating in a low power mode. A reservoir-loading configuration (RLC) (41,42,59) loads a reservoir up to a specific pressure when the reservoir pressure falls below a threshold value. The RLC has a switch valve to switch the second pump to a mode for reservoir loading.
