<P>PROBLEM TO BE SOLVED: To reduce the number of parts when installing metal diaphragm dampers in a low pressure fuel passage, and prevent shortage of parts and incorrect assembling. <P>SOLUTION: A pressure pulsation reducing mechanism includes a pair of metal dampers with two disk-like metal diaphragms joined over the entire circumference to form a hermetically sealed space inside a joined part, with gas sealed in the hermetically sealed space of the dampers, has a pair of pressing members for giving pressing force respectively to both outer surfaces of the metal dampers at a position on the inner diameter side than the joined part, and is unitized, with the pair of pressing members connected while holding the metal dampers. <P>COPYRIGHT: (C)2012,JPO&INPIT |
