<p>PURPOSE:To prevent any cloudy phenomenon in lubricating oil from occurring by forestalling a drain flowing into a high-pressure side cylinder from a suction chamber of a cylinder head. CONSTITUTION:A cylinder head 21 is installed on a high-pressure side cylinder 9 so as to make a suction chamber 22 turn to the lower side and a discharge chamber 23 to the upper side respectively, and an inlet port 22B of the suction chamber 22 is set up so as to make it downward and to be opened to a bottom side (nearer to the cylinder 9), while a high-pressure side pipe part 24C of an intermediate pipeline 24 is connected to the inlet port 22B so as to extent it downward as its constitution. Accordingly, in time of the shutdown of a compressor, each drain produced in the suction chamber 22 and the intermeduate pipeline 24 is all flowing into the side of the intermediate pipeline 24 from the inside of the suction chamber 22 via the inlet port 22B set up at the bottom side, and it is conducted to the side of an intermediate pipe part 24B to be situated at the lower side together with another drain produced in the intermediate pipeline 24.</p> |
