Abstract

1384993 Fuel injection pumps FRIEDMANN & MAIER AG 29 Jan 1973 [27 Jan 1972] 4436/73 Heading F1A The barrel 5 containing the reciprocable plunger 2 of a fuel injection pump has an inwardly extending rim 8 defining an outlet passage 9, a coaxial delivery valve 6 being in sealing contact with the rim over an annular area 11 having an inner diameter a less than the diameter b of the plunger 2. A valve holder 7 screwed into the body 1 of the pump contacts the valve 6 over an annular area 12 and maintains the contact between the valve 6 and the barrel. The outer diameter c of the area 11 is equal to or smaller than the plunger diameter b. In a second embodiment the inner diameter d of the area 12 is less than the plunger diameter b. In a further embodiment, Fig. 3 (not shown) the areas 11, 12 are frustoconical instead of annular.
