Pressure control valve

Abstract

The invention relates to a pressure control valve, composed of a valve component and a drive component for the control element of the valve component; the valve component has an orifice that is closed by the control element in a first position, thus disconnecting a control chamber from a return chamber and during operation, a control pressure prevails in the control chamber that is greater than or equal to the return pressure in the return chamber, and in the first position, the control pressure acts on a first control surface of the control element and in a second, controlled position, the orifice is partially opened so that the control chamber and the return chamber are fluidically connected to each other and the control pressure prevailing in the control chamber in the second position acts on a second control surface of the control element and the second control surface is larger than the first control surface.
