<p><P>PROBLEM TO BE SOLVED: To adjust a volume ratio between an inner cylinder chamber and an outer cylinder chamber. <P>SOLUTION: An annular piston (40) is stored in a cylinder chamber (60, 65) eccentrically to a cylinder (35), and the cylinder chamber (60, 65) is partitioned into the outer cylinder chamber (60) and the inner cylinder chamber (65). A blade (45) partitions the respective cylinder chambers (60, 65) to high pressure chambers (61, 66) and low pressure chambers (62, 67). The heights (H1, H2) along the rotating axis center direction of the outer cylinder chamber (60) and the inner cylinder chamber (65) are set different from each other. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
