Abstract
The invention relates to a distribution and control valve in a fuel injection engine pump especially for a large multi-cylinder diesel engine, in which the fuel is injected into the cylinder by mdans of two or more injection valves (A;B). The pump includes a pump cylinder (1) and, inside thereof in a pump chamber (2), a reciprocatingly movable piston member (4), which is arranged through its movement to feed fuel via distribution ducts to the injection valves of the cylinder in question. The pump cylinder (1) is provided with an extra chamber (11) connected to the pump chamber (2), to which extra chamber there is tightly adapted a long-shaped valve member (12) following the movements of the piston member in the axial direction thereof, and inside the valve member (12) there is a fuel duct (13) connected to the pump chamber (2). The feed ducts (16;5a,5b) of the separate valves are connected to the extra chamber (11) in the axial direction of the valve member (12) to different points distant from each other. The valve member (12) is provided with control and feeding means to direct fuel in a desired way from the pump chamber (2) to the feed ducts (16; 5a, 5b) of each injection valve (A;B).
