<p><P>PROBLEM TO BE SOLVED: To suppress outflow of lubricating oil from a cam chamber storing a cam body such as a swash plate. <P>SOLUTION: Inside a rotational shaft 14, a passage 142 inside the shaft is formed. The passage 142 inside the shaft is communicated with a suction chamber 131. Introduction holes 27A, 27B are formed in a base part 161 of the swash plate 16 and the rotational shaft 14 so as to be communicated with the passage 142 inside the shaft. The cam chamber 17 is communicated with the passage 142 inside the shaft via the introduction holes 27A, 27B formed on the rotational shaft 14. Wall faces of the introduction holes 27A, 27B are formed, such that the length of preceding parts 381A, 381B preceding first accompanied by rotation of the rotational shaft 14 is set longer than the length of following parts 371A, 371B most delayed accompanied by rotation of the rotational shaft 14. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
