Abstract

709,837. Fuel-Injection pumps. VOZIDEL, U.M., and BOTTGER, J. Dec. 5, 1951 [Dec. 5, 1950], No. 28512/51. Class 102 (1). The delivery valve of a fuel-injection pump comprises a cylindrical member 2 lapped to fit the bore of a housing 1 The member 2 has a head pressed by a spring 3 against the end of the housing 1 and the sten of the member has an annular groove 4 which is intercepted by longi tudinal grooves 8 that taper towards the an nular groove and have open ends 9. The housing has an annular groove 5 which is connected by ports 10 to the delivery pipe leading to the engine cylinder. At low engine speeds the member 2 is lifted until the annular grooves coincide and lift of the member is determined by the minimum cross-section 6 of the grooves 8. As the engine speed increases, the lift of the member 2 increases and a larger crosssection of the grooves 8 is available for fuel flow. Taking into account the relief action on the fuel in the delivery pipe, the delivery valve results in the pump having a falling delivery characteristic with increasing speed. Reference has been directed by the Comptroller to Specification 673,107.
