Abstract:
1. An arrangement for controlling the fuel supply in a fuel supply apparatus, which arrangement comprises: a body part defining a space through which fuel to be injected flows during operation, and also defining a fuel inlet opening and a fuel discharge opening, which open into said space, and a piston member movably disposed in said space and having a front face oriented towards the fuel inlet opening, wherein the arrangement defines a flow path to provide flow communication between the fuel inlet opening and the fuel discharge opening, the flow path includes at least one throttle section between the inlet opening and the front face of the piston member in the flow direction of the fuel, the throttle section is formed by at least one opening in the body part, and the body part comprises an outer part and an inner part bounding therebetween a space enabling fuel flow communication between the at least one opening that forms the throttle section and the fuel inlet opening, and the cross-sectional flow area of the throttle section depends on the mutual positions of the piston member and the body part.
