Claims

[Claims for Utility Model Registration] (1) At least one rotor of a pair of rotors that synchronously rotate once in opposite directions without contacting each other is fixed concentrically to the outside of a rotation center body. In a non-contact rotating machine, the non-contact rotating machine is provided with a blade that rotates integrally with the rotation center body while being in close contact with the outer peripheral surface of a fixed hollow body, and the working chamber is configured such that the volume changes in a hermetically sealed manner for a predetermined period of time. A counterweight space is formed in the casing between a fixed part of the hollow body and a bearing supporting the rotation center body, and the counterweight space is provided with a counterweight coupled to the rotation center body. Counterweight structure of contact rotating machine. (2) During the period when the working chamber communicates between its minimum volume state and intermediate volume state, the working chamber communicates with the center of rotation through the communication port formed in the fixed hollow body and the opening/closing port formed in the center of rotation. A counterweight structure for a non-contact rotating machine as set forth in claim 1 of the registered utility model. (3) By tightening the split formed in the counterweight with a tightening tool, the fitting portion of the counterweight is tightened around the rotation center body, so as to connect the counterweight and the rotation center body. A counterweight structure for a non-contact rotating machine according to claim 1 or 2 of the registered utility model claim.
