<P>PROBLEM TO BE SOLVED: To provide a pulsation damper for preventing leakage of fuel with pressure in abnormality of a diaphragm, with simple structure. <P>SOLUTION: Fuel pressure pulsation of a fuel line is reduced by the diaphragm 3 disposed between a fuel chamber 2 communicating with the fuel line, and an atmospheric releasing chamber 4 communicating with the atmosphere through a hole 5. A moving plug 6 is disposed to the hole. Since the moving plug moves outside of the atmospheric releasing chamber to close the hole in abnormality of the diaphragm, the hole is closed by utilizing the pressure itself from the fuel chamber. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
