Abstract

472,460. Liquid - fuel injectors. FRENCH, L. 0. Feb. 12, 1937, Nos. 4249 and 4250. Convention dates, Feb. 12, 1936 and Oct. 24, 1936. [Class 7 (iii)] [Also in Group XXVIII] A fuel-injection pump comprises a plunger 25 within a sleeve 28 having a port 34 at its lower end and ports 32 at the upper end of the pump chamber. The discharge valve 115 seats in a member inserted in the sleeve 28 and the loading spring 116 engages conical faces 117 on the valve and 118 in the casing, so that the valve remains stationary while the sleeve 28 is rotated and the seat is kept clean. A pin 115<1> on the valve keeps the injection orifice 106<1> clear. In a modification, the valve is loaded by a resilient plate which bears against the back of the valve which is grooved so that the grooves are tangential to the injection orifice in the plate.
