  • Publication number: 20030107623
    Abstract: In a pump driver for selectively driving a plurality of pumps, a sun gear is rotated by a single drive source. A planetary gear is meshed with the sun gear. A planetary carrier rotatably supports the planetary gear revolvably around the sun gear. A plurality of driving gears are arranged in a one-by-one manner with respect to the pumps such that the planetary gear meshes with one of the driving gears to selectively drive one of the pumps. A revolution limiter allows a revolution of the planetary gear in a first direction and restricts a revolution of the planetary gear in a second direction opposite to the first direction at a position where the planetary gear meshes with one of the driving gears.
