The invention relates to a pressure control valve (1) comprising a control piston (3) which is able to slide in a valve hole (4). Under the effect of an energy accumulator (5) said piston in one direction of displacement connects a pump connection (23) with a consumer connection (24) and in the other direction of displacement connects the consumer connection (24) with a tank connection (21) such that the pump connection (23) is closed off. The aim of the invention is to provide a pressure control valve which functions reliably and in a stable manner even in case of elevated control dynamics. To this end, independently of the direction of displacement of the control piston (3) a minimum volume flow present between the piston and the valve hole (4) dampens the displacement of the control piston (3).

1. A pressure control valve comprising a control piston that can be displaced in a valve bore, wherein said control piston connects a pump connection to a load connection in one direction of travel under the effect of an energy storage device, and connects the load connection to a tank connection while disconnecting the pump connection in the other direction of travel, and further wherein the volume flow between the control piston and the valve bore causes a damping of the movement of the control piston independently of the direction of travel of the control piston.
