Title: Improvements in or relating to fuel-injection pumps for internal combustion engines
IPC: F02M59/26
Filed: 1936-01-11
Abstract: 467,741. Fuel - injection pumps. RETEL, J. M. R. Jan. 11, 1936, No. 982. Convention date, Jan. 11, 1935. [Class 102 (i)] A fuel-injection pump in which the rotation of the pump piston causes simultaneously a variation in the advance of the time of injection and a variation in the quantity of fuel injected and further means for rendering the quantity of fuel injected dependent upon the speed of the engine and independent of the advance of the time of injection. Fig. 1 shows a pump in which a helical edge 6 co-operates with the suction port 2 and a radial port 7 in the piston, connected by a longitudinal bore 8 to the pump chamber 1, co-operates with an inclined edge 9 in the sleeve 10. The sleeve 10 is connected by pinions 11, 12 to a speed governor. The piston is adjusted by the pinion 35. As shown in Fig. 2, suction takes place through port 24 in the sleeve 21 and the quantity is controlled by the co-operation of the port 15 in the piston and an inclined edge of the port 24. The port 15 is connected to the pump chamber 14 by a longitudinal bore in the piston. The pump chamber has a spring loaded piston 16 and injection commences when the helical edge 18 uncovers the discharge port 20. The sleeve 21 is rotated by a connection to a speed governor. The maximum quantity of fuel injected is controlled by adjusting the sleeves 21, 22 axially. In Fig. 3, the fuel passes through the suction port 25 and is trapped between the pump piston and the spring loaded piston 26. Discharge takes place when the helical edge 28 uncovers the discharge port 29 and ceases when the helical edge 30 uncovers the byepass port 31. In addition the discharge is proportional to the time that elapses between the uncovering of ports 29, 31 and is thus proportional to the speed of the engine. A relief port 34 is provided which is controlled by the piston 26.
