Title:
DISTRIBUTION TYPE FUEL INJECTION DEVICE
Document Type and Number:
Japanese Patent JPH11153067
Kind Code:
A
Abstract:

To provide a distribution type fuel injection pump to improve wear resistance of a feed pump slide part.

A distribution type fuel injection pump pressurizes and distributes and feeds with a pressure fuel through rotational movement and reciprocation movement of a pump plunger 11. A plate part 47 formed of a material having wear resistance further excellent than that of the material of a pump housing 6. This constitution, since wear resistance of a feed pump slide part is improved, the occurrence of wear of a plate by the vane 47 is reduced. Thereby, when the number of revolutions of a rotor is one and the same, a delivery amount of a vane type feed pump higher than a given amount is ensured for a long period of time. Further, an injection timing is properly controlled by a timer part, and the output of an engine is improved and exhaust gas emission is reduced.
