Abstract:
A pressure control valve for regulating the oil pressure in an oil supply system, with a first working chamber which is in connection with an oil line, with a second working chamber which is in connection with an oil supply line, and with a control slide valve which is substantially movable by the oil pressure in the first working chamber, with the control slide valve releasing the throttling aperture when exceeding a first predetermined oil pressure in the first working chamber, through which the oil from the second working chamber is released into a recirculation system, and with the control slide valve having a control element arranged as a piston which is movable in the axial direction by the oil pressure in the second working chamber relative to a main body of the control slide valve and which on exceeding a second predetermined oil pressure in the second working chamber releases the throttling aperture through which oil from the second working chamber is released into the recirculation system, characterized in that the main body is provided with a guide rod on which the piston is displaceably held in the axial direction and that the control slide valve will release the throttling aperture via the same control edge both when exceeding the first predetermined oil pressure in the first working chamber as well as when exceeding the second predetermined oil pressure in the second working chamber.
