Abstract

1317913 Fuel injection pumps MITSUBISHI JUKOGYO K K 8 June 1970 [9 June 1969] 27708/70 Heading F1A The delivery valve 5 of a fuel injection pump closes against a conical seat at the end of a passage in a member 4 and when, before actual seating, a suck-back collar 6 thereon prevents flow from chamber 22 to the pumping chamber 23, a guide portion 7 progressively decreases the flow from the passage to the chamber 23. As shown, the portion 7 successively covers a plurality of axially spaced conduits 11 leading, via an annular chamber 12, to the pumping chamber 23. During delivery from the chamber 23, a non-return valve 10 opens thereby bypassing the conduits 11. In a second embodiment, Fig. 3 (not shown), the guide portion 7 has a conical lower end which enters a restricted opening (27) between the passage in the member 4 and the chamber 23, thereby progressively decreasing the flow.
