The invention discloses a star-spinning type rotation device with double sun wheels, an engine and a fluid machine. A spin valve plate sun wheel is installed in the middle of a main sun wheel, and all pressure or parts of pressure are pressed on the spin valve plate sun wheel when spin valve plates are opened. Due to the facts that the spin valve plate sun wheel can be independent of the main sun wheel to rotate and the rotation of the main sun wheel is absorbed by bearings arranged between the spin valve plate sun wheel and the main sun wheel, severe friction produced by the relative motion between the valve plates and an outer cylinder surface of the main sun wheel is prevented, and the service life and efficiency of the star-spinning type rotation device are improved.
