Abstract

The invention relates to a hydraulic control arrangement comprising a pump, by which means a plurality of consumers, preferably at least three, can be supplied with a pressure medium. The pressure medium is supplied by a distributing valve arrangement embodied as an LS, LUDV or throttle control block. According to the invention, a hydraulic engine is mounted downstream of a consumer having a low load and is driven by the pressure medium flowing away from said consumer.
