Abstract

1474216 Fuel injection pumps CATERPILLAR TRACTOR CO 19 Aug 1974 [22 Aug 1973] 36426/74 Heading F1A A fuel injection pump has a delivery valve 26 having an annular portion 28 which engages a seat 24 provided on the end of the pumping cylinder 10 and a central bore 46 normally closed by a check-valve 50, the delivery valve and the check valve being urged towards their closed positions by co-axial springs 32, 56. The check-valve 50 is operative after closure of the delivery valve to relieve excess pressure downstream thereof. Variable thickness spacers 58 are used to adjust the compression of the spring 56.
