Abstract

In a fuel injection system comprising solenoid operated fuel injectors 10 fed by a pump 14 with fuel at a constant pressure regulated by a pressure relief valve 31, a pressure operated check valve 40 between the pump and the injectors prevents fuel flowing out through an injector which sticks in the open position when the engine is stopped. The valve 40 comprises a spring-loaded disc valve 51 of plastics material, the spring abutment 40 of which is also of plastics material. A check valve may also be provided in the return pipe 32.
