Abstract

A fuel injection pump has a shuttle 23 actuated by feed pump pressure to deliver a measured quantity of fuel to the injection pump cylinder via a port 21 and passages 20, 14. A one way valve 35 is provided in the or each passage 20 to isolate from the passage 14 any cavity formed in the fuel near the shuttle end of the passage 20 when the shuttle 23 abuts the discharge end of its cylinder.
