High-pressure pump

A high-pressure pump configured to perform pre-stroke metering to return a part of fuel, which is suctioned from a fuel gallery into a pressurization chamber, to the fuel gallery, the high-pressure pump comprising:

• a housing which forms a contour;
• a cylindrical seat body disposed in the housing and having an inner periphery defining a valve seat;
• a valve configured to sit on the valve seat by at least a fuel pressure on a side of the pressurization chamber so as to block the pressurization chamber from the fuel gallery;
• a stopper having a regulation portion configured to make contact with an end surface of the valve, which is lifted, to regulate a lift amount of the valve from the valve seat, the regulation portion defining an accommodation space at a center of the regulation portion to be filled with fuel;
• a cylindrical sleeve disposed around the regulation portion and integrally formed with the regulation portion;
• and
• a fuel passage configured to communicate the pressurization chamber with the accommodation space, wherein
• the fuel passage extends in a direction perpendicular to a direction in which the valve is slidable,
• the stopper having;
• a bottom portion closing an end portion of the accommodation space on a side of the pressurization chamber, and
• a stopper passage located between the fuel passage and the pressurization chamber,
• the stopper passage is defined by only the stopper, and
• the fuel passage is formed in the stopper and configured to communicate the accommodation space with the pressurization chamber in a state where the valve is in contact with the stopper.
