Abstract

818,197. Fuel injection systems; valve gear. BESSIERE, P. E. Jan. 28, 1957 [Jan. 31, 1956; Aug. 1, 1956], No. 2928/57. Classes 7(3) and 7(6) In a multicylinder engine having a single injection pump 1 feeding a number of injectors 12 with spring-loaded fuel injection valves opened by fuel pressure, the supply pipe 11a...d to each injector is provided with a second valve 14 held closed by an electro-magnet 16 and opened by fuel pressure when the electromagnet is deenergized during the injection period of its associated injector. The pump 1 delivers into a chamber 10 to which are connected the injector pipes 11a-d each of which is connected to a recess 19 in an injector body 15 in which slides the valve 14 connected to the electromagnet armature 17 and controlling the passage 13 leading to the injection valve. The electromagnets 16a...d, Fig. 2, are controlled by a rotating distributer device 20 on an extension of the pump camshaft 2 the distributer having conducting strips 21a...d with insulating. segments which ensure de-energization of the electromagnets at the appropriate times. The period of injection is controlled by an electromagnetically operated by-pass valve 34 on the chamber 10 which is opened before the end of each pumping stroke to by-pass fuel through orifice 32 and terminate injection. The electromagnet 25, which is normally energized to hold valve 24 closed, is de-energized at appropriate intervals by insulating segments 35 on a rotating conducting strips 34, Fig. 3. combined with the distributer 20, Fig. 2. The segments 35 are inclined so that the period of injection can be adjusted by movement of the strips 34 axially, or of the brush 33 along the strip, either manually or automatically by a governor. The valves 14 may be mounted on the wall of chamber 10 instead of in the injectors.
