Claims

[Claims for Utility Model Registration] (1) Each rotor has a reference cylindrical surface, a blade fitting portion that has a depressed portion from the reference cylindrical surface and communicates with the outer circumference of the blade, and the blade fitting portion The rotors, each configured to have a vane adjacent to the recess and protruding from the reference cylindrical surface, synchronously rotate in opposite directions in mutually exclusive contact with each other, and the hollow rotor The rotor is configured to rotate closely around the hollow body, and the rotor that meshes with the rotor on the hollow body side has only one blade, and the reference cylindrical surfaces of each rotor are in close contact with each other. The rotating machine is configured such that the outer circumference of the blade of the rotor that meshes with the rotor on the hollow body side is in close contact with the hollow body, and the blade fitting part of the rotor on the hollow body side and the blade fitting part of the rotor on the hollow body side are Focusing on the blade that fits into the blade, a predetermined part that connects to the outer periphery of the blade in the part where the blade fits in is the same blade as a predetermined part that connects to the outer periphery of the blade in the blade fitting part of the rotor. A predetermined portion that is created by the intersection with the outer circumferential portion and that communicates with the reference cylindrical surface of the blade side surface of the same blade and the reference cylindrical surface of the blade fitting portion of the rotor on the hollow body side. The structure is such that one part is created by all or a part of the other part, and furthermore, focusing on the working chambers sandwiched between the blades of each rotor, the working chamber's During a period for communicating between the minimum volume state and an intermediate volume state of the working chamber having a predetermined value larger than the minimum volume of the working chamber, the portion into which the blades of the rotor of the rotor on the hollow body side are fitted communicates with the hollow body. A rotating machine characterized by being configured to communicate with the hollow body through an opening. (2) The rotating machine according to claim 1 of the utility model registration claim, wherein the rotating machine is a pump. (3) The rotating machine according to claim 1, wherein the rotating machine is an expander. (4) The rotating machine according to claim 2 or 3 of the utility model registration claim, wherein the rotor on the hollow body side has one blade. (5) The rotating machine according to claim 2 or 3 of the utility model registration claim, wherein the rotor on the hollow body side has two blades. (6) The rotating machine according to claim 2 or 3 of the utility model registration claim, wherein the rotor on the hollow body side has three blades. (7) Focusing on the blades of the rotor that mesh with the rotor on the hollow body side, we formed a thin groove along the rotor's rotational axis direction on the outer periphery of the blade, and also created a missing circular part where the outer periphery of the blades of the same blade were in close contact with each other. is formed in the hollow body, and the width of the missing circular portion is larger than the width of the narrow groove.
The rotating machine according to any one of Items 6 to 6.
