Claims

[Scope of utility model registration request]

a first container having an air inlet; a second container hermetically coupled to the first container, communicating with the atmosphere and having oil sealed therein; rotatably and airtightly supported by the second container; a communication port communicating with the second container, a first spiral protrusion located in the first container, and a diameter larger than the diameter of the communication port. a first scroll provided with a discharge port located at the center of the first spiral protrusion and communicating between the first spiral protrusion and the communication port; rotatably supported by the first container; a second scroll having a second spiral projection that cooperates with the first spiral projection to form a compression chamber, and rotationally driving one of the first scroll and the second scroll; a check valve that checks the flow path between the discharge port and the communication port, a cylindrical valve holder that regulates the movement dimension of the opening side of the check valve, and a cylindrical valve holder arranged on the outer periphery of the valve holder. and a compression coil spring that urges the check valve toward the compression chamber, and the valve holder includes a cylindrical body with an outer diameter smaller than the diameter of the communication port, and a cylindrical body with a diameter smaller than the diameter of the communication port. 1. A scroll fluid machine comprising: a through hole penetrating from the direction; and a flange provided on the communication port side of the cylindrical body, from which the communication port can be partially exposed.
