A valve arrangement forming the fuel injector of a combustion engine fuelled by gas has a servo valve (10) and a pilot valve (20). The servo valve regulates a flow of fuel from the inlet (13) to the outlet (14) of a main conduit (12). The pilot valve (20) comprises an electromagnetically-controlled plate valve located in a subsidiary conduit S which connects the main conduit (12) to a further outlet (23). The pilot valve controls the differential pressure of fuel across the servo valve causing the latter to regulate the flow in the main conduit (12). |
