Abstract
A high-pressure pump is comprised of a lower housing, an upper housing and a cover, which are formed independently from each other. Thereby, shapes of the above can be simplified. Although the cylinder and the plunger receive a fuel pressure during a pressurization stroke, the upper housing and the cover do not receive fuel pressure directly from a pressurization chamber. Therefore, the upper housing and the cover can be made thin and light as much as possible.
