A fuel pump for a direct injection internal combustion engine having a body with a valve seat. The valve includes a valve head and the valve is movably mounted to the body between an open position and a closed position. In its open position, the valve head is spaced from the valve seat white in its closed position, the valve head abuts against the valve seat and closes the valve. An electric coil upon energization moves the valve to an open position and, conversely, upon deenergization allows the valve to move to a closed position. A control circuit controls the energization of the coil to reduce the pump noise during operation of the engine, especially at low speeds.
