A specially designed rotary actuator comprising a sealed container and a piston rotor located in the sealed container. The piston rotor divides the sealed container into a first space and a second space having different pressures. The first end of the piston rotor faces the first space and includes a plurality of first bores, and the second end of the piston rotor faces the second space and includes a plurality of second bores. The depth of the first and second bores is less than the thickness of the piston rotor. Each of the first and second bores comprises a first portion and a second portion, wherein the surface area of the first portion is greater than the surface area of the second portion.
