Abstract

In a fuel supply pump, a laminated valve structure (24) for opening and closing a suction passage (22) and a discharge passage (23) is provided in a pump body (6). The laminated valve structure includes first and second reed valves (26 resp. 27) and a valve plate (25) disposed between the first and second reed valves, and is provided with two suction holes (24a) and two discharge holes (24b). The first reed valve has two suction side movable valve elements (26a) for opening and closing the suction holes. The second reed valve has two discharge side movable valve elements (27a) for opening and closing the discharge holes.
