Patent ID: 7229063

Claim:
A pressure control valve for regulating pressure in a hydraulic circuit of a vehicle transmission, the pressure control valve comprising; a valve housing containing a solenoid coil, an armature rod, an armature, and a spring, the control valve further comprising a yoke and a push rod which are located between the armature rod and a control element, the spring biasing the control element, via a pin and the push rod, against a valve seat of the seat plate, and an end of the pin ( 12 ), remote from the push rod, has a contact disk ( 14 ) which abuts against a complementary contact disk ( 13 ) of the armature rod to prevent further movement of the pin ( 12 ) toward the valve seat; the push rod ( 7 ) and the pin ( 12 ) being axially aligned with one another, the armature rod ( 1 ) having a longitudinally through bore in which the pin ( 12 ) is accommodated, the pin ( 12 ) having a fixed length and being made of a material, wherein inherent temperature expansions and reductions of the pin, compensate for thermal expansions/reductions of the plastic flange, and whereby the distance of the valve seat plate from the yoke remains constant.
