High pressure fuel supply pump

A high pressure fuel supply pump, comprising:

• an electromagnetic suction valve that adjusts an amount of fuel sucked into a pressuring chamber;
• a discharge valve that discharges the fuel from the pressuring chamber;
• and
• a plunger that is able to make a reciprocating motion in the pressuring chamber,
• wherein the electromagnetic suction valve includes an electromagnetic coil, a suction valve, and a movable portion that is able to be operated in a direction closing the suction valve by a magnetic attraction force when the electromagnetic coil is energized,
• wherein the movable portion includes an anchor portion that is driven in a direction closing the suction valve by the magnetic attraction force and comes into conflict with a fixed member to stop moving, and a rod portion that is driven in conjunction with the anchor portion and is able to keep its moving even after the anchor portion stops moving,
• wherein the electromagnetic suction valve includes a first spring that biases the suction valve in a direction to be closed, a second spring that biases the suction valve through the rod portion in a direction to be opened, and a portion that sets a gap between the anchor portion and the fixed member to be at a predetermined position after the electromagnetic coil is energized, and
• wherein the anchor portion is released from the magnetic attraction force, and moves together with the rod portion in a direction opening the valve, and
• wherein after the rod portion stops, the anchor stops the motion by a third spring in the anchor portion and by contacting the rod portion.
