Hydraulic power transmission circuit

摘要

The invention relates to a hydraulic power circuit comprising two receivers 3,4 each fed by a pump 1,2, a flow limiter 22 being arranged in the joint return pipe 25 of the circuits of the receivers and being driven by a pressure which is a function of the pressures in the feed pipes, by means of a driving device. This driving device comprises two restrictions 27,28 arranged between the feed pipes 7,8 and the control member 22b for the flow limiter 22. One application is the production of the control circuit for a hydraulic shovel. IMAGE
