Abstract

1475528 Fuel injection pumps NIPPONDENSO CO Ltd 26 July 1974 [28 July 1973] 33106/74 Heading F1A In a fuel injection pump having a piston with control edges 1 and 2' which co-operate with a spill port 3' to determine the beginning and end of injection, respectively, the spill port 3' has a polygonal shape when developed, at least some of the sides being parallel to portions of the edges 1 and 2'. The control edges 1, 2' are formed from straight portions c', d' and a', b', the portion c', d' possibly being separated by a third portion perpendicular to the cylinder axis and the portions a', b' possibly being separated by a further inclined portion, Fig. 4 (not shown).
