<p><P>PROBLEM TO BE SOLVED: To provide a high-pressure fuel pump reduced in the number of parts and the size. <P>SOLUTION: A discharge valve 80 is installed in a discharge section 70 formed integrally with a housing body 11. A spring seat member 81 of the discharge valve 80 is accommodated inside a discharge passage 23 formed in the discharge section 70. Movement of the spring seat member 81 accommodated in the housing body 11 is restricted by a ring 85, and the spring seat member is held by the housing body 11. Consequently, binding between the housing body 11 and the discharge section 70 is unnecessary, and a sealing member to be provided between the housing body 11 and the discharge section 70 for preventing fuel leak is unnecessary. The spring seat member 81 is formed in a cylindrical shape, and a first passage 91 and a second passage 92 are formed in the spring seat member 81 to secure a passage through which the fuel pressurized in a pressurization chamber 15 flows. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
