Abstract
896,701. Fuel injection pumps. BESSIERE, P. E. Dec. 18, 1958 [Dec. 24, 1957], No. 40929/58. Class 102(1). A fuel injection pump comprises a main piston 1 reciprocating in a cylinder 3 provided with an inlet 4, an outlet 5 and a by-pass conduit 7. The by-pass conduit 7 is controlled by a slide valve 8, loaded to the closed position by a spring 9 and actuated hydraulically by liquid delivered by a piston 11 which reciprocates in synchronism with the main piston 1. On the delivery stroke of piston 11, liquid first passes through a conduit 27 to close a slide valve 30 and then flows past a non-return valve 15 to act on the end of the slide valve 8. This pressure acting on the end of the slide valve is controlled by the flow through a conduit 17 and a restricted outlet 21 formed by a groove 19 in the slide valve. The pistons 1, 11 are reciprocated at engine speed and for low speeds, the pressure acting on the end of the slide valve is not sufficient to move this valve against the spring loading and the maximum amount of fuel is delivered. When the speed of the engine is such that the pressure acting on the end of the slide valve 8 starts to move the valve upwards, this upward movement reduces the constriction 21 which further increases the pressure on the end of the slide valve. When the constriction 21 is closed, the slide valve moves quickly to open the by-pass conduit 7 practically simultaneously with the closing of this restriction, and a second groove 23 then opens the conduit 17 sufficiently to maintain the valve in its upper position. The return movement of the valve 8 is controld by flow through the open valve 30 and a throttle 31, preferably adjusted by a speed governor. This brakes the return movement of the slide valve so that, for engine speeds above a predetermined value, the slide valve does not complete its return stroke before being again actuated by the delivery of the piston 11. The spring loading may be adjusted by a screw 10 and the lower position of the valve, and hence the initial value of the constriction 21, by a screw abutment 22.
