PURPOSE:To set up tow suction passages different in length to be so compact in size, by setting up a normal primary suction passage long in pipe length and a high-speed secondary suction passage short in pipe length in a specified state in a way of utilizing a distant difference ranging from each cylinder row to a suction distributor box. CONSTITUTION:A suction passage 16 is divided into a normal primary suction passage 17 long in pipe length and a high-speed secondary passage 18 short in pipe length, and both these suction passages 17 and 18 are led into an interval between each cylinder row 2. The primary suction passage 17 is extended toward the side of the cylinder row 2 opposed to the cylinder row 2 leading to this passage 17, and interconnected to a suction distributor box 11 at he upper part. The secondary suction passage 18 is extended upward as it is, and interconnected to the suction distributor box 11 at the side of the cylinder row 2 leading to this passage 18. The primary suction passage 17 is alternately installed side by side between each suction distributor box 11, and these adjacent passages themselves are interconnected to cylinders 3 different in suction timing each, while they are interconnected with each other by an interconnecting passage 21 provided with a control valve 22. |
