High-pressure fuel pump assembly |
摘要 |
<p>The present invention relates to a high-pressure fuel pump assembly 200, which supplies high-pressure fuel from a fuel supply port 9 to a delivery pipe 1a, wherein the high-pressure fuel pump assembly 200 comprises: a high-pressure pump 20 having an intake valve 22 and a discharge valve 21; a fuel discharge passage 4 connecting the discharge valve 21 to the fuel supply port 9; and a high-pressure damper 60 disposed in the fuel discharge passage 4; and a first check valve 210, which opens when the pressure on the voluminous chamber side is a fixed value lower than the pressure on the discharge valve side, is provided within the fuel discharge passage 4 between the high-pressure damper 60 and the discharge valve 21. The first check valve may be a ball valve or a reed valve, and a second check valve may be provided between the fuel supply port 9 and the high-pressure damper 60. The cross-sectional area of the fuel discharge passage 4 may be equal to or greater than the cross-sectional area of the fuel outlet 4a along the entire length of the fuel discharge passage 4. <IMAGE></p> |
