Abstract

Improvements in liquid fuel pumping apparatus for supplying fuel to an internal combustion engine and of the kind comprising, in combination, a pump cylinder in which a cylindrical bore, a pump plunger mounted within the bore, is practiced, an outlet from one end of the bore and through which fuel is driven by inward movement of the plunger during a pumping stroke thereof, a discharge valve mounted on said outlet, said discharge valve including a slotted guide portion which it can slide in a cylindrical part of the outlet and the discharge valve also has a head part that cooperates with a seat to prevent the circulation of fuel into the bore from the outlet during the outward movement of the piston, characterized in that the outlet between the discharge valve and the cylindrical bore is restricted, to prevent the part of guide enters the cylindrical bore in the event that its head part detaches from the slotted part of guide.
