ABSTRACT:
A valving system for reversing flow in a compressing device. The reversible compressor includes a reversible drive motor for reversing a rotational direction of a rotor, a first and second port located in a left and right side of a stator, respectively, and a first and second manifold located on a right a left side of said reversible compressor, the first and said second manifold includes a corresponding first and second inlet valve moveable between an open and closed position. A valving system between said first and said second manifold switches one of the first and second inlet valve to an open position to open a corresponding first or the second port for directional flow corresponding to the rotational direction of the rotor. In a first embodiment the valving system is a pressure-actuated control element and in a second embodiment the valving system includes a solenoid.
