Abstract

See full text

High pressure fuel pump includes a cylinder which is fitted in a concave portion formed in a pump housing and which defines a compression chamber of the pump and a plunger which pressurizes, by sliding against the cylinder, the fluid in the compression chamber. It is structured such that the fluid sucked into the compression chamber by reciprocating motion of the plunger is pressurized and is then discharged from the compression chamber. The cylinder is formed of a cylindrical member which has a ceiling portion and in which the compression chamber is partitionedly formed. A fuel suction path formed in the pump housing reaches the compression chamber through the cylinder and a fuel discharge path formed in the pump housing is connected to the compression chamber through the cylinder. The cylinder is pressed against the pump body by a fuel pressurizing force applied to the cylinder.
