Radial piston pump and wind power generator

Abstract

To provide a radial piston pump capable of displacement control without using an electronic control valve. For achieving the above object, the radial piston pump includes: a first cam circumferentially varying in radius on an inner circumferential side or outer circumferential side of the cam in a continuous manner; a second cam circumferentially varying in radius on an inner circumferential side or outer circumferential side of the cam in a continuous manner; a first operation member operating along a side of the first cam on which the radius of the cam continuously varies; a second operation member operating along a side of the second cam on which the radius of the cam continuously varies; a first piston connected to the first operation member; a second piston connected to the second operation member; a cylinder connecting with the first piston and the second piston and varied in volume by motion of at least one of the first piston and the second piston; and an adjustment unit for rotating at least one of the first cam and the second cam.
