摘要 |
<p>The present invention provides an axial plunger pump which does not need bellows by restricting fuel to a cylinder bore (13) configuring a pump portion and by lubricating the other portion with oil. The high pressure fuel pump comprises a plunger (11) reciprocating according to a shaking movement of a swash plate (9), a cylinder block (12) forming a pump chamber (14) together with the plunger (11), and a sealing member provided between the plunger and a cylinder bore for sealing oil leaked from the pump chamber (14) to a chamber surrounding the pump chamber (14), wherein oil in the oil chamber is supplied from the outside of the high pressure fuel pump. <IMAGE></p> |
