Abstract (en)
In a fuel injection pump employing an inner cam system, inflow / outflow ports (31) for taking in and cutting off fuel are formed at a rotor (8) that rotates in synchronization with an engine, a communicating hole (40) that is capable of coming into communication with these ports (31) is formed at a control sleeve (34) and two inclined edges (31a,31B,40a,40B) are formed inclining in opposite directions from a hypothetical line extending parallel to the axis at an opening end of each of the inflow / outflow ports (31) and the communicating hole (40). The inclined edges (31a,40a) of the inflow / outflow ports (31) and of the communicating hole (40) that cross each other at the end of communication between them are formed parallel to each other and the inclined edges (31B,40B) that cross each other at the start of their communication are formed parallel to each other. This achieves a full advance angle at startup of the engine without having to rely on a timing device in the fuel injection pump employing an inner cam system. Even after startup, the oil feed rate at medium to low load can be raised while keeping the drive torque under the permissible value at high load. <IMAGE>
