Abstract

PURPOSE:To avoid forming a pump in a large size by utilizing a dead space so effectively, installing a relief passage, interconnecting an exhaust port to a low pressure fuel chamber, in a distribution head, and setting up an on-off valve in this relief passage. CONSTITUTION:A relief port 55 leading to a pressure-feed pump chamber 14 is installed in a side wall of a plunger 8. And, an exhaust port 56 is installed in a cylinder 51. In a distribution head 50, there is provided with a relief passage 57 which interconnects this exhaust port 56 to a low pressure fuel chamber. Then, an on-off valve 58 is installed in this relief passage 57. These relief port 55, exhaust port 56, relief passage 57 and so on can be installed in utilizing a dead space lying between the low pressure fuel chamber and the pressure-feed pump chamber 14. Thus, enlarging the size of the pump is avoidable.
