Abstract
Provided is a high-pressure fuel pump in which responsiveness of closing a suction valve can be maintained even when the high-pressure fuel pump is increased in pressure or capacity of the high-pressure fuel pump is increased, thereby ensuring discharge efficiency. Therefore, the high-pressure fuel pump includes the rod that urges the suction valve in the valve opening direction, the mover that drives the rod in the valve closing direction, and the solenoid that generates a magnetic attraction force for moving the mover in the valve closing direction. After the suction valve starts moving from the suction valve closing position in the valve opening direction, the rod reaches the suction valve closing position and further moves in the valve opening direction.
