Abstract

1,271,799. Fuel injection pumps. C.A.V. Ltd. Sept. 5, 1969 [Sept. 24, 1968], No.45242/69. Heading F1A. In a fuel injection pump having a spill port 14 communicating with the pumping chamber and a fuel gallery 15, the port is formed from inner and outer connecting bores the axes of which are off-set. The bores are arranged such that fuel spilled from the pumping chamber via a helical groove 16 on the plunger 10 into port 14 undergoes turbulent flow before entering the gallery thus reducing wear in the gallery walls.
