Title: Fuel injection pump and unit injector using it
Inventor: KANEKO TAKASHI
IPC: F02M57/02
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To generate pressure opposite to negative inertia force so as to prevent jumping from occurring by constituting a fuel injection pump so that fuel in a plunger chamber is drained to a drain oil hole through a passage formed by a small drain oil groove following to drain from a drain oil groove. SOLUTION: A plunger 4 is pushed downward (state A). When the upper edge 4a of the plunger 4 as injection starting control lead closes a feed/drain oil hole 20, compression of fuel in the plunger chamber 12 begins (state B). When the plunger 4 descends further, the large drain oil groove 10 of the plunger 4 is communicated to the feed/drain oil hole 20 of a plunger barrel 5 (state C). When the plunger 4 is further pushed down, a small drain oil groove 10b is communicated to the feed/drain oil hole 20. The passage area of the small drain oil groove 10 is small, the volume of the plunger chamber 12 is contracted, and hence pressure of the plunger chamber 12 is raised (state D). Hereby pressure opposite to negative inertia force is generated, and hence jumping is prevented from occurring.
