Claims

[Scope of utility model registration request]

A variable capacity compressor equipped with a check valve in a release port provided in the cylinder, a refrigeration cycle circuit that sequentially communicates the variable capacity compressor with a condenser, a pressure reducing device, and an evaporator via a refrigerant pipe, and A release circuit that connects to the low pressure side of the refrigeration cycle circuit to reduce capacity,
a check circuit branched from the high pressure side of the refrigeration cycle circuit and communicating with the release port via an auxiliary capillary to close the check valve during normal operation;
A refrigeration cycle device equipped with a variable capacity compressor, characterized in that a strainer tank is provided on the upstream side of the auxiliary capillary of the check circuit, and has a piping capacity larger than the piping capacity on the outlet side of the auxiliary capillary.
