<P>PROBLEM TO BE SOLVED: To provide a high-pressure pump capable of sufficiently functioning a damper member and sufficiently suppressing pulsation of a fuel. <P>SOLUTION: A damper unit 32 is disclosed, including a damper member 35 and a support member 36. On a circumference edge of the damper member 35, a separation section 37 in a shape of expanding upward and downward is formed, and further a welded section 38 is formed in such a manner that damper plates are again bent from the separation section 37 into directions to be closer to each other and butt-welded. The damper member 35 is supported in a tilted state by the support member 36. By tilting the damper member 35, a stream along an upper diaphragm 33 is formed by the fuel circulated from a passage 58 close to a pressurizing section to a fuel gallery 31. This stream is suppressed between the diaphragm 33 and a cap 14 constituting the fuel gallery 31. <P>COPYRIGHT: (C)2012,JPO&INPIT |
