Abstract

1,229,919. Fuel injection pumps. BRYCE BERGER Ltd. Nov. 1, 1968 [Nov. 30, 1967], No. 54565/67. Heading F1A. In a fuel injection pump, preferably of the "spill-port type" whose plunger is reciprocated by a cam driven tappet, the pump barrel 10 has a flanged portion bearing on a shoulder 12 of the pump body 11, and the plunger 15 has a leakage collecting groove 16 that can communicate with the suction chamber 14 via a drilling 17, machined flat 18 in the narrower portion of the pump barrel and machined depression 19 in the flanged portion of the barrel. It is stated that the depression and flat may be machined in one operation by an end mill and that, alternatively, the pump body may be machined to the necessary clearance.
