<p>A rotary expanding or compressing mechanism provided in a fluid channel with blades for traversing a shaft comprises a supporting frame (1), an import (2) and export (3) of the fluid channel, a un-round type curve barrel stator (4), a rotor (5) with concave grooves, blades (6) for traversing a shaft, a round end cap (7) and a member (8) for transmitting force. Wherein, a movable wearable sealing member (9,10,11) is provided in the matching position between the blade (6) and the stator (4). The mechanism is of good wearlessness and energy efficiency.</p> |
