Abstract: 1471388 Regulating fuel injection GKN TRANSMISSIONS Ltd 23 May 1975 [21 June 1974] 27572/74 Addition to 1417703 Heading F1B Fuel injection apparatus described in the parent Specification which includes a carburetter, has the blow-off valve replaced by an assembly which controls in a mutually exclusive mode, supply of fuel to the jet element of the carburetter and supply of fuel to the outlet of the fuel injection apparatus. The assembly comprises a pressure regulating valve element 45 spring-loaded against a seat in a bush 48, which regulates the pressure in a chamber 51  communicating with the high-pressure space (15), Fig. 1 (not shown), at the delivery side of a highpressure pump (13) which supplies the fuel injectors. Fuel which is supplied to a chamber 57 under low-pressure from the inlet side of the highpressure pump (13) passes to the carburetter jet assembly via port 58, the flow being controlled by a valve element 56 subject to the magnetic attraction of the armature 59 of an electromagnet. On starting the engine, the electromagnet is energized and the armature moves to the right, as viewed from Fig. 3, carrying element 56 with it which allows fuel to pass to the carburetter; also, pushrod 66 projecting from the armature unseats valve element 45 to stop high-pressure building up in chamber 51, thereby preventing fuel delivery via the fuel injectors. After starting, the electromagnet is de-energized and the armature moves to the left under the action of spring 64, shutting off fuel flow to the carburetter and allowing valve element 45 to reseat, thereby permitting pressure build-up in chamber 51 which allows fuel to be delivered via the injectors. When the engine is on over-run, a lower current may be passed through the coil to allow the armature to unseat valve element 45 whilst leaving valve element 56 seated, the engine thereby receiving no fuel from either the carburetter or injectors. Alternatively, separation of element 56 from the armature may be effected by fuel pressure build-up within a chamber 65.
