ABSTRACT:
A pressure control valve for a fuel injection system is proposed which serves to control the warm-up fuel quantity for a mixture-compressing, externally ignited internal combustion engine. The pressure control valve includes a movable valve part which is urged in the closing direction by a compression spring which is counteracted during the warm-up phase by a first temperature-dependent element, whose force on the compression spring below a predetermined temperature in the direction of an increase in the force of the first temperature-dependent element can be influenced by a second temperature-dependent element, so that the fuel-air mixture during the warm-up phase can be adapted to the requirements of every internal combustion engine.
