Title:
INJECTION PUMP, AND FUEL FEED DEVICE OF DIESEL ENGINE WITH THE INJECTION PUMP
Document Type and Number:
WIPO Patent Application WO/2003/074864
Kind Code:
A1
Abstract:
An injection pump, wherein a sleeve (12) is disposed near an area where the outer peripheral surface of a plunger (26) faces an oil reserving chamber (11) in the inserted state onto the plunger, a sleeve port (121) allowing the inner peripheral surface of a hole in which the plunger is inserted to communicate with the outer peripheral surface of the sleeve facing the oil reserving chamber (11) is formed in the sleeve, and a sleeve actuator (65) vertically moves the sleeve by rotating sleeve drive members (13) disposed in injection pump elements (2), whereby the stroke position of the plunger (26) where a cutout (263) cut off from the oil reserving chamber by the inner peripheral surface of the sleeve (12) at a position lower than the sleeve port is allowed to communicate with the sleeve port becomes a fuel injection termination position of an effective stroke.
