Abstract

1,267,555. Fuel injection pumps. MASCHINENFABRIK AUGSBURG NURNBERG A.G. Nov. 27, 1969 [Dec. 21, 1968], No.58126/69. Heading F1A. In a fuel injection pump having a delivery valvemember 4 mounted in a valve 3, the member has a fruster-conical sealing surface 7 and a further fruster-conical portion 10 separated by a groove 9. The dimensions of the groove 9 are chosen to provide an adequate relief volume when the associated engine is operated at low load e. g. during idling, and the conicity and axial length of the portion 10 are so chosen in relation to the strength of the valve spring 11 that the pressure in the delivery conduit is substantially constant throughout the local range of the engine. In another embodiment Fig. 6, (not shown) the portion 10 has an upper cylindrical portion (15) adjacent the groove 9.
