<P>PROBLEM TO BE SOLVED: To provide a delivery pipe for reducing pressure vibration in a fuel supply passage without the need for greatly changing the shape of a housing. <P>SOLUTION: A diaphragm 5 is mounted in the housing 2 to block the fuel supply passage 2a of the delivery pipe 1. The diaphragm 5 consists of a flange portion 5a and a hollow protruded portion 5b protruded to one side of the flange portion 5a. A plug 3 is threaded to the housing 2, whereby the flange portion 5a of the diaphragm 5 is held between the plug 3 and the housing 2 and fixed to the housing 2 via a seal member 4 and an additional seal member 6. In the state that the diaphragm 5 is mounted in the housing 2, a slack space C is formed inside the protruded portion 5b where the diaphragm 5 can slacken. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
