Abstract
There is proposed a pressure regulating valve for a fuel injection system which serves to regulate the heating-up fuel amount for an explosion, external auto-ignition, internal combustion engine. The pressure regulating valve comprises a movable valve component which is urged in the closing direction by a pressure spring which during the heating-up phase acts against a temperature responsive element which in turn acts with a force that can be influenced by another temperature responsive electrically heatable element so that during the heating-up phase the air-fuel mixture can be proportioned in accordance with the requirements of each internal combustion engine.
