Abstract:
1. A fuel injection pump comprising: a plurality of rotary deflectors against which spilled fuel impinges, the spilled fuel being fuel that (i) outbursts from a plunger room and is injected into inlet/spill ports drilled in a plunger barrel and (ii) then flows into a fuel gallery when fuel injection ends, wherein each of said rotary deflectors comprises: wherein said rotational axis, around which said rotatable tip member rotates, extends in a direction that the spilled fuel is injected into the inlet/spill ports of the plunger barrel, wherein said rotatable tip member includes a spilled fuel inlet hole (i) located in a center of said rotatable tip member, (ii) extending in a direction of said rotational axis, and (iii) opening into the inlet/spill ports of the plunger barrel and a spilled fuel outlet hole or holes of said rotatable tip member, and wherein said spilled fuel outlet hole or holes are radially located around said rotatable tip member to open into the fuel gallery and to communicate to said spilled fuel inlet hole, such that at least a portion of the spilled fuel injected into the inlet/spill ports of the plunger barrel travels through said spilled fuel inlet hole and is expelled through said spilled fuel outlet hole or holes causing said rotatable tip member to rotate around said rotational axis.
