<P>PROBLEM TO BE SOLVED: To solve a problem that when a refrigerant gas moves from a cylindrical part of a communication pipe to a suction hole, resistance of a flow passage increases and efficiency of a compressor decreases due to stepwise change of a cross-sectional shape and decrease of a flow passage area in the communication pipe, an outlet of the communication pipe and the suction hole. <P>SOLUTION: A suction hole 152 is formed in a similar shape to that of an outlet 138 of a communication pipe so as to have a larger flow passage area than that of the outlet 138 of the communication pipe, and by forming a gradually changing part 139 of the communication pipe which continuously connects a cross-sectional shape of a cylindrical part 137 of the communication pipe and a cross-sectional shape of the outlet 138 of the communication pipe, the resistance of the flow passage generated when the refrigerant gas moves from the cylindrical part 137 of the communication pipe to the outlet 138 of the communication pipe is minimized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
