<P>PROBLEM TO BE SOLVED: To provide a high-pressure pump seal used for a fuel injection pump for direct-injection engine, capable of reducing a man-hour for assembly even if a resin material is used in a part of a seal member for pressure resistance and heat resistance by simplifying the structure of a housing as a mating part, and capable of increasing the wear resistance of a rubber seal. <P>SOLUTION: This high-pressure pump seal comprises the rubber seal 11 vulcanized/adhered to a reinforcement ring 4 and slidingly moving in close contact with a shaft 2, the resin seal 21 fitted to the reinforcement ring 4 and axially moving and slidingly moving in close contact with the shaft 2, and a finger spring 5 installed between the reinforcement ring 4 and the resin seal 21. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
