ABSTRACT:
A distributive type fuel injection apparatus including a fuel distribution plunger mounted for rotary and reciprocating motion in a cylinder that defines a fuel pressure chamber, an inlet passage communicating with a fuel reservoir, and a plurality of discharge ports each providing communication between the pressure chamber and a different one of an engine's power cylinders. The plunger defines discharge passages for sequentially registering with the discharge ports and an overflow passage providing communication between the pressure chamber and the fuel reservoir. A control valve automatically closes the overflow passage during certain engine operating conditions and selectively opens the overflow passage during other engine operating conditions in synchronism with the registration between the discharge passages and only predetermined ones of the discharge ports.
