PURPOSE:To prevent the trouble due to vibration by allowing the discharge side and suction side of a compressor to communicate to two heat exchangers through a check valve and allowing a high pressure passage and low pressure passage to communicate by integrally connecting the check valve with the compressor, thus removing a pipe for coolant circulation. CONSTITUTION:A plurality of cylinders 3 and 3 are installed into the head parts 2 and 2 on the both sides connected with a crankcase 1 of a compressor A, and a two-head type piston 4 is installed in slidable ways in each cylinder 3, 3. In this case, a cover body 5 having a communication passage is arranged outside one head part 2, and a check valve B is arranged outside the other head part 2. The check valve B has a suction inlet (s'') communicating to a low pressure passage (s) on a plane 19 which is formed closely to a valve chamber R in a body case 16 on a basic board 13 and a discharge port (d'') communicating to a high pressure passage (d), and the through holes (e) and (f) connected to two heat exchangers are formed. |
