Abstract:

The present invention addresses the problem of preventing engine start faults caused by moisture adhering to a control rack of a fuel injection pump and the moisture freezing. This fuel injection pump (1) installed in a diesel engine (30) is provided with: a control rack (20) which is disposed in a rack chamber (5) formed between a pump head (3) and a pump housing (2), and adjusts the fuel injection amount; a transmission shaft (49) rotatably supported in a transmission shaft hole (2C) formed in the pump housing (2); and a lubricant passage (2D) which is formed in the pump housing (2) and forcibly feeds a lubricant between the transmission shaft (49) and the transmission shaft hole (2C). An oil path (40), through which a portion of the lubricant forcibly fed through the lubricant passage (2D) passes, is formed in the transmission shaft (49), a first opening part (41A) of the oil path (40) communicates with the lubricant passage (2D), and a second opening part (42A) of the oil path (40) is formed on the outer peripheral surface of an upper portion of the transmission shaft (49) in the proximity of the control rack (20).
