PURPOSE:To increase the coefficient of performance of a compressor and to prevent generation of noises caused by the contact of a small tube with an outer tube, by cooling a cylinder body effectively by an injection liquid coolant. CONSTITUTION:A compressed coolant is discharged into an enclosed container 7 as a high-temperature, high-pressure gas and tends to heat a cylinder body 9 and part of a liquid coolant carried through a capillary tube 3 after by-passing a condenser 2. However, since the liquid coolant is insulated from the outside by a round tube 21 inserted and fixed tightly in an injection tube 5, the direct cooling effect of the liquid coolant to the gas coolant in a cylinder 8 is promoted, and the temperature rise of the coolant caused when the coolant is compressed is reduced, so that the coefficient of performance of a compressor can be raised. Further, vibration due to contact between a small tube 19 and an outer tube 20 can be eliminated. |
