Abstract:
A high-pressure fuel supply pump including an electromagnetically driven intake valve is configured such that a pressure equalizing hole is provided in the valve stopper positioned between the valve and a pressurizing chamber. The pressure equalization hole connects a spring storage space, provided between a valve and a valve stopper, with a surrounding fluid passage. The high-pressure fuel supply pump is further configured such that an opening of the pressure equalizing hole at the spring storage chamber side is open at a position at the inner side of a diameter of the spring. Since the pressure in the pressurizing chamber can be introduced into the inner side of the spring without traversing the spring, the unstable behavior of the spring or the valve due to the introduced pressure eliminated. Since the force applied to the valve when the valve closes is stabilized, the closing timing of the valve is stable.

Claim (Index 1):
A high pressure fuel pump comprising:\n a pressurizing chamber provided in a pump body, a valve opening and closing a fuel passage communicating with a pressurizing chamber, a valve stopper in contact with the valve in a full valve opening position, and a spring biasing the valve in a valve closing direction provided in a space between the valve and the valve stopper; wherein the valve stopper includes a hole connecting to the space and the pressurizing chamber, and a guide portion for guiding opening and closing the valve, wherein the valve includes a bottom portion in contact with the spring, and a cylindrical portion guided by the guide portion, and wherein a inner peripheral surface of the cylindrical portion faces the spring.
