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.
Abstract translation: 高压泵由彼此独立地形成的下壳体，上壳体和盖组成。 由此，能够简化上述的形状。 虽然气缸和柱塞在加压冲程期间接收燃料压力，但是上壳体和盖子直接不从加压室接收燃料压力。 因此，可以尽可能地使上壳体和盖体变得薄且轻。

Abstract: During a pressurization stroke of a high-pressure pump, a cylinder inner wall and a plunger receive a fuel pressure from the pressurization chamber. Meanwhile, an upper housing does not receive the fuel pressure from the pressurization chamber, so that its thickness can be made thin. A cylinder is comprised of a bottom portion, a cylindrical portion and a large-diameter cylindrical portion. When inserting the large-diameter cylindrical portion into a large engaging hole, the bottom portion and the cylindrical portion are not brought into contact with a lower housing. A high liquid-tightness between the bottom portion, the cylindrical portion and a small engaging hole can be ensured.
