ABSTRACT:
The invention concerns a pressure control valve for the control of the value of pressure in a hydraulic circuit, especially in a hydraulic circuit of a vehicle transmission, with a valve housing, with a solenoid coil, with an armature component group comprising an armature rod, an armature and advantageously, a spring, with a yoke and with a push rod, which is interposed between the armature rod and a control element, whereby the section of the valve housing (3) in the zone of the control element (16) consists of a plastic flange (2a), and further, the armature rod (1) possesses a control boring in the longitudinal direction, in which a pin (12, 12′, 12″) is inserted, the material and dimensioning are so selected, that the pin can compensate for a temperature based longitudinal change of the plastic flange (2a).
