<p><P>PROBLEM TO BE SOLVED: To improve volumetric efficiency in a piston type compressor using rotary valves. <P>SOLUTION: Lead-in passages 31, 32 are formed in a rotating shaft 21 so as to communicate with a passage 212. Suction passages 33A, 34A are formed in cylinder blocks 11, 12 so as to serve for communication between cylinder bores 27A, 28A and a shaft hole 112. With the rotation of the rotating shaft 21, the lead-in passages 31, 32 intermittently communicate with the suction passages 33A, 34A. The cylinder blocks 11, 12 directly support the rotating shaft 21 through the rotary valves 35, 36 integrally formed at the rotating shaft 21. A thrust bearing 26 is provided with a thrust load absorbing function. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
