A high-pressure pump includes a plunger for pressurizing a fuel, a cylinder accommodating the plunger reciprocatably in its axial direction and a pump body. The pump body defines a pressurization chamber, a low-pressure fuel passage hydraulically connecting a fuel inlet and the pressurization chamber, and a discharge passage. The pump body further defines a cylindrical space around the cylinder. The fuel flows into the cylindrical space from the low-pressure fuel passage so as to cool the cylinder. The entire outer surface of the cylinder can be surely c...
1. A high-pressure pump comprising: a plunger for pressurizing a fuel;a cylinder accommodating the plunger reciprocatably in its axial direction, the cylinder having a large-diameter cylindrical portion, a tapered portion and a small-diameter cylindrical portion arranged sequentially in an axial direction of the cylinder, wherein the tapered portion has an increasing wall thickness that gradually increases in the axial direction of the cylinder toward a pressurization chamber, wherein each of the large-diameter cylindrical portion and the small-diameter ...
