Abstract

1322694 Fuel injection pumps NIPPONDENSO CO Ltd 10 June 1971 [22 June 1970] 19971/71 Heading F1A The combined inlet and spill port 9 of a fuel injection pump is provided with a chamfered inlet end,preferably 30 degrees, and a constant diameter portion having a length (1) to diameter (d) ratio (<SP>1</SP> d ) not greater than 0À4. It is stated that a port having these dimensions improves the sucking efficiency and minimizes the normal decrease in delivery which results when the temperature of the fuel increases.
