Injection pump for a piston engine with rotatable plunger

摘要

A plunger (2) with constant stroke of an injection pump for a piston engine is rotatable to regulate flow rate and has at least one control cam (7, 8) which releases a connecting channel (9, 10) with a non - round cross section to the suction chamber to end the injection procedure. Each channel has a flat wall section which runs from the edge (12) first passed over by the control cam at the end of injection parallel to the control cam.
