Abstract

1470507 Fuel injection system CAV Ltd 9 May 1974 [12 May 1973] 22720/73 Heading F1B A fuel injection system includes an injection nozzle 14 having a valve-member 15 which is resiliently loaded to the closed position, a fuel injection pump 10 supplying fuel to the nozzle which causes the valve-member to move to the open position, the valve-member 15 defining a valve surface which is exposed to fluid-pressure generated by a further pump assisting the resilient loading, and a quantity control member 13 controlling both the amount of fuel supplied per stroke to the nozzle and the fluid-pressure applied to the valve surface-of the valve-member. The pump 10 has an auxiliary pump outlet 18 under control of the member 13, the valve surface being exposed to fluid-pressure taken between a pair of restrictors 20, 21. Alternatively a separate pump (23) may be provided, the fluid-pressure being derived between a restrictor (25) and a control valve (26) under the control of the quantity adjusting member (13a), Fig. 2 (not shown).
