Claims

[Scope of utility model registration request]

A refrigeration cycle is constructed by sequentially connecting a compressor, a condenser, a pressure reducer, an evaporator, a first gas-liquid separator, and a second gas-liquid separator with a pipe line, and one end is connected to the evaporator. The other end of the inflow pipe is opened into the first gas-liquid separator, and one end is connected to the suction port of the compressor, and an oil return small is provided at a portion located in the internal allowance of the second gas-liquid separator. The other end of the outflow pipe in which the hole was formed is opened at the upper part of the second gas-liquid separator, and a small hole for oil return is formed at the bottom of the first gas-liquid separator to allow the refrigerant to advance. A connecting pipe is formed with a rising part rising in the direction, one end of which opens into the upper part of the first gas-liquid separator, the other end of which opens into the second gas-liquid separator, and one end of which opens into the upper part of the first gas-liquid separator. A refrigeration device in which a connecting pipe line opening at the upper part of the gas-liquid separator and the upper part of the rising part are connected by a thin tube and opened.
