A fuel pump for internal combustion engines comprises a feed of the vane type, and distributer conveying to each engine cylinders. is fed through passage d, Fig. 1, inlet outlet ports being connected by non-return valve e which limits pressure generated. from conveyed m, past an annular groove n cavity o contains manually operated throttle p. passes along q in turn radial r k, driven spindle 5 motion engine, thence bore s pump. During inward movement plungers h, 2, returned single port t feeds cylinders passages u. Ports 3 distributer, similarly situated r, convey 2 one side plunger w, 2. The on w causes rotation cam j, against springy, opposite direction k. When h encounter lobes they impart return so long as open via 3. closed locked hydraulically perform their discharge movement.
