Claims

[Scope of utility model registration request]

A seat portion comprising a compression housing 60 having a cylinder chamber 62 formed therein, an intermediate port 3 provided at an intermediate portion between an intake port 1 and a discharge port 2 that open into the cylinder chamber 62, and formed around the intermediate port 3. The capacity control valve device is configured such that a valve body 11 is seated or separated from a valve body 10 to block or communicate the intermediate port with the suction port 1, and the valve body 11 is seated or separated from the intake port 10, and the intermediate port 11 is placed in the compression housing 60 at a position where the intermediate port 3 is formed. A through hole 4 having the same diameter is formed from the outer surface of the housing 60 to the cylinder chamber 62, and a valve seat 13 having a capacity control hole 13a is installed inside the through hole 4. The seat portion 1 is placed around the capacity control hole 13a.
1. A capacity control valve device for a compressor, characterized in that the capacity control valve device forms a zero.
