Abstract

690,563. Fuel injection pumps. C.A.V., Ltd. May 9, 1951 [June 14, 1950], No. 14837/50. Class 102 (i). A fuel injection pump has a non-return inlet valve b, disposed at or near the discharge end of the barrel n, through which the fuel can be supplied from an auxiliary pump e or other source at a pressure above atmospheric, and an escape port (or ports) k is provided in the barrel adjacent the position occupied by the plunger i at the end of the suction stroke so that during each suction stroke the barrel can be flushed by the flow of fuel through the said port. This prevents the release of occluded air from the fuel during the suction stroke and therefore the possibility of frothing. The inlet valve b is of annular form and is loaded by a spring c. The fuel is delivered through a passage f controlled by a delivery valve g.
