Abstract
A fluid feed apparatus includes a suction hole and a discharge hole for a fluid, a fluid transfer part provided between a rotor and a stationary member containing the rotor, a shaft coupled with the rotor, a rotation actuator for rendering a relative rotating motion between the shaft and the stationary member in a surface perpendicular to an axis of the shaft, a driving power supply for the rotation actuator, a rotating motion control unit for the rotation actuator, a swing actuator for rendering a relative swinging motion between the shaft and the stationary member, a driving power supply for the swing actuator, and a swinging motion control unit for the swing actuator. Synchronous control is performed by the rotating motion control unit and the swinging motion control unit so that the rotating motion and the swinging motion are synthesized to implement a revolving motion.
