Abstract
A fuel injection pump for internal combustion engines having a diversion bore disposed in the pump cylinder and controlled by a control edge on the pump piston. The diversion bore is embodied as a stepped bore having a segment of smaller diameter and a segment of larger diameter downstream of the segment in the flow direction. A liner which is not vulnerable to cavitation is disposed in the segment and is held in its working position by a resilient device, and a return flow conduit is formed between a chamber of lower pressure and an inlet to the bore of the liner.
