Patent ID: 7491037

Claim:
A reversible compressing device consisting essentially of: a reversible drive motor for reversing a rotational direction of a rotor rotating within a stator having a stator body extension in one portion of the stator; a first and a second flow port located in a left side and a right side of said stator, respectively; a first and a second manifold located on said right side and said left side of said stator, respectively, said first and said second manifold enclosing a corresponding one of a first inlet valve and first flow port and a second inlet valve and second flow port, wherein said first and said second inlet valve are moveable between an open and a closed position; and an actuator movably located in a passageway of the stator body extension between said first and said second manifold for automatically moving one of said first and said second inlet valve to said open position to open a corresponding one of said first port and said second port for flow corresponding to the rotational direction of said rotor, in neutral operation the actuator is centered partially opening each of the first and second inlet valve until rotation in one of a clockwise and a counter-clockwise direction creates a pressure in a corresponding one of the right and left manifolds automatically moving the actuator to move the one of the left and right inlet valves to open the one of the left and right inlet ports and the opposite one of the left and right inlet valve functions normally to open when pressure increases above pressure in the opposite side to allow pressure to exit.
