Abstract
1367337 Fuel injection pumps SOC INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE 2 Dec 1971 [4 Dec 1970] 55896/71 Heading F1A The opening of the delivery valve 4 of a fuel injection pump is resisted by a spring 5 and by fuel in a chamber 16 having to be displaced by the valve through a passage 18, 17, 19 to a supply chamber 26, 8, the passage being so arranged that it decreases in flow area with increasing valve opening. In the closed position of the valve shown the groove 17 in the valve 4 aligns with the passage port 19. After a predetermined valve lift the groove moves out of alignment with the passage 19, whereafter further flow from the chamber 16 is restricted by having to flow through a small annular clearance (a), Fig.3 (not shown) between a reduced diameter portion (4c) of the valve and the bore 14 in which it slides. Fuel delivered past the valve enters an annular chamber 13 and flows therefrom through a passage 24 to a delivery line 6. In the event of a pressure wave occurring in the line 6 after closure of the valve 4, the pressure pulse is received in the chamber 13 and acts on a frusto-conical valve surface therein, thereby to cause re-opening of the valve.
