A rotating apparatus and rotating system applying a pressing gate valve mechanism. In the rotating apparatus and the rotating system, a pressure fluid cavity (11) is provided at the outer side of a gate valve groove. The motion of a gate valve (30) is controlled by using the fluid pressure, so that a gate valve transmission mechanism and a control mechanism that are in a mechanical form are omitted. The rotating apparatus and the rotating system have the advantages of being simple in structure, high in reliability, high in maintainability, and the like. Based on the rotating apparatus and the rotating system, also provided are a corresponding fluid motor, compressor, pump, and compressor. |
