Hydraulic valve assembly, hydraulic valve block with such a valve assembly, and hydraulic drive with it

摘要

Disclosed is a hydraulic valve arrangement for supplying pressure medium to a hydraulic consumer, which has two working connections for connection to the consumer, with a first inlet orifice plate, via which a first feed flow from the first of the working connections to the consumer is controllable, and a separate second return orifice plate, over which a first return flow from the consumer via the second working port is controllable, and with a second inlet orifice through which a second feed stream from the second of the working ports to the consumer is controllable, and a separate first return orifice, via which a second return flow from the consumer via the first working port is controllable. Disclosed are furthermore a hydraulic valve block with at least one such valve arrangement and a hydraulic drive with a hydraulic pump, at least one hydraulic consumer and at least one such valve arrangement or such a valve block.
