Abstract

A regulating apparatus is proposed for a fuel supply system for a mixture-compressing, externally ignited internal combustion engine, which serves to enrich the fuel-air mixture furnished to the engine when it is started cold and while it warms up. The regulating apparatus comprises a pressure-regulating valve which sets the fuel pressure, the closing force of which on the movable valve part is influenced by a temperature-dependent element by means of a relay device and a regulating spring coaxially correlated therewith. Accordingly in a predetermined temperature range, the temperature-dependent element and the movable valve part are connected only by the regulating spring.
