Abstract
Diesel engine fuel injection pump comprises a piston with control surfaces for the beginning and end of an injection cycle, acting in conjection with parts in the wall of the cylinder which connect with a chamber around the cylinder. The chamber receives fuel via a feed line from a fuel pump and an overflow line is provided for excess fuel at the end of the injection stroke. At the entry to the overflow line throttle means are provided containing at least two throttle points in series. Shut-off valves are provided in the feed line to prevent the pressure wave generated during overflow from entering.
