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 of which is configured to have a blade protruding from the reference cylindrical surface while being adjacent to the recessed portion, rotate synchronously in opposite directions at different rotational speeds in a non-contact state, and It is a rotating machine configured so that the reference cylindrical surfaces are in close contact with each other, and the blades that form the blade fitting part of the rotor on the opening side that opens on the inner wall surface of the side casing of the high pressure passage are focused on. A predetermined wall surface that communicates with the outer periphery of a rotor that is connected to the outer periphery of a blade that forms a blade fitting portion of a rotor that meshes with a rotor that has a blade fitting portion adjacent to a blade that fits into the blade fitting portion. The working chamber is configured so as to be created by the part that connects to the outer circumference of the blade at the tip, and furthermore, the working chamber is sandwiched between the blades of each rotor, and the minimum volume state of the working chamber and the working chamber are During the period of communication with an intermediate volume state having a predetermined value larger than the minimum volume of A rotating machine characterized by being configured to communicate with an opening that opens into the (2) Pay attention to the blade of the rotor that meshes with the rotor on the side of the opening that opens on the inner wall surface of the side casing of the high pressure passage, and check the line of the cross section of the side surface of the blade on the back side of the part where the blade fits, and the line where the blade fits. A line of a cross section of a predetermined portion that connects to a reference cylindrical surface of a wall surface forming a rotor blade fitting portion on the opening side opening into the inner wall surface of the side casing of the high-pressure passage; The rotating machine according to claim 1, which is constructed such that the line is created by all or a part of the other line. (3) Claims 1 or 2 for registration of a utility model in which the number of blades of the rotor on the side of the opening opening in the inner wall surface of the side casing of the high pressure passage is two, and the number of blades of the rotor meshing with the rotor is one. Rotating machinery as described.
