Abstract

962,829. Fluid-pressure servomotor systems. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. Nov. 28, 1961 [Dec. 21, 1960], No. 42541/61. Heading G3P. [Also in Division F1] Fuel is continuously injected into an I.C. engine induction pipe 1, Fig. 1, downstream of a manual throttle valve 2 by a pump 4 connected to a calibrated orifice 10, upstream of which is aligned a smaller calibrated orifice 11 and a chamber 8, the degree of opening of which to a surplus fuel pipe 14, and hence the injection pressure, is determined by a spring-loaded valve 12. Upstream of the throttle valve 2 is a spring-urged lift valve 15 which continues to open until the negative pressure between the valves 2 and 15 balances the force of the spring 19 loading the valve 15. The valve 12 is attached to a pair of diaphragms 30, 31 and actuated by admitting fluid to the space therebetween through orifices 25, 26 and 33; orifices 25 and 33 are open to atmosphere, the area of the latter being determined by the position of a spring-opened valve 36 which is movable towards the closed position by a lever 39 on the throttle valve 2; orifice 26 is variable by a rotary, or as shown a needle valve 28 integral with the valve 15. The valve 36 may also be adjusted by supplementary factor e.g. the negative pressure in the induction pipe downstream of the throttle, the temperature of the ambient oil or the temperature of the engine lubricating oil or exhaust gases. In various modifications, the valve 15 is constituted by a piston-actuated plug-valve, a horizontal lift valve or a butterfly valve 15b, Fig. 5, on an eccentric spindle 24 having a counterweight 19b; the spindle 24 is provided with a roller 40 for actuating the needle valve 28. The orifice 25, which opens to the engine air intake upstream of the butterfly valve 15b, may be variable in dependence upon the position of the butterfly valve 15b, in which case the orifice 26 is fixed. The orifices 10, 11 open obliquely into the induction pipe. The air-fuel mixture may be adjusted by means in addition to or instead of the valve 36 for ensuring cold starting.
