Title:
High-pressure pump
Document Type and Number:
Japanese Patent JP6264403
Kind Code:
B2
Abstract:
A fuel gallery has an inlet opening through which a fuel is introduced therein and a suction opening through which the fuel flows between the fuel gallery and a compression chamber. A pulsation damper is supported in the fuel gallery by a first and a second supporting member. The second supporting member defines an inner fuel chamber and outer fuel chamber which communicates with each other through apertures. The suction opening is located at a side wall of the fuel gallery and the inlet opening is located at a bottom wall of the inner fuel chamber which is defined radially inside of the second supporting member. The fuel discharged into the outer fuel chamber through the suction opening is introduced into the inner fuel chamber through the apertures. A flow velocity of the fuel is decreased and a pressure pulsation reduction effect of the pulsation damper is surely achieved.
