Ventilpatrone

摘要

The valve unit proposed has a housing (10) and at least one pump connection point (P), a reservoir connection point (T) and a consumer connection point (A) plus a pressure limiting valve (20) and a control valve (18) incorporated in the same assembly, the two valves (18, 20) being connected in parallel to each other between the pump connection point (P) and the reservoir connection point (T). The valve unit proposed enables hydraulic circuits for the protection of hydraulic pumps and/or for the balanced starting of a hydraulic pump, as well as for the reduction of the pressure at a hydraulic consumer, to be designed to fit in a very small space. In the event of damage, the valve unit can be rapidly replaced by a new one, thus avoiding long consumer down times.
