摘要： PROBLEM TO BE SOLVED: To prevent an overpressure loss in a cylinder chamber (C2) having a delivery port (48) with a small opening area, in a compression mechanism (20) provided with a plurality of cylinder chambers (C1, C2) having different capacity. SOLUTION: A delivery port (46) with a small opening area out of plural delivery ports (45, 46) is made to serve as a small diameter side delivery port, a delivery port (45) having larger opening area than that of the small diameter side delivery port (46) is made to serve as a large diameter side delivery port, the delivery valve (48) opening/closing the small diameter side delivery port (46) is made to serve as a small diameter side delivery valve, and a delivery valve (47) opening/closing the large diameter side delivery port (45) is made to serve as a large diameter side delivery valve. For example, the small diameter side delivery valve (48) and large diameter side delivery valve (47) are formed to have the same dimension in plate thickness, and the width dimension (W2) of the small diameter side delivery valve (48) is formed smaller than the width dimension (W1) of the large diameter side delivery valve (47). Therefore the rigidity of the small diameter side delivery valve (48) can be reduced lower than that of the large diameter side delivery valve (47). COPYRIGHT: (C)2008,JPO&INPIT

SOLUTION: The annular cylinder chamber C1, C2 of a cylinder 21 is partitioned into an outer cylinder chamber C1 and an inner cylinder chamber C2 by an annular piston 22. The cylinder 21 is eccentrically rotated by the driving of a motor 30, and the displacement of each of the outer cylinder chamber C1 and the inner cylinder chamber C2 is changed. The displacement ratio of the inner cylinder chamber C2 to the outer cylinder chamber C1 is set to approximately 0.7.

摘要： PROBLEM TO BE SOLVED: To provide a rotary compressor capable of ensuring the high compression efficiency without increasing mechanical losses even when an operating condition of the rotary compressor changes. SOLUTION: In a compression mechanism (30) of the rotary compressor, cylinder chambers (60, 65) are formed of a cylinder (40) and a second housing (50). A back side space (75) is formed between an end plate part (41) of the cylinder (40) and a flat plate part (36) of a first housing (35). The first housing (35) has a communication passage (81) and a differential pressure valve (82). When the difference between the discharge pressure and the suction pressure is small, the discharge pressure is introduced into an intermediate space (77) through the communication passage (81), since both the pressure in an inner space (76) and the pressure in the intermediate space (77) become the discharge pressure, the pressure applied to the cylinder (40) is increased. On the other hand, when the difference between the discharge pressure and the suction pressure is large, the communication passage (81) is blocked by the differential pressure valve (82), the pressure in the intermediate space (77) becomes the intermediate pressure lower than the discharge pressure, and the pressure working to the cylinder (40) is decreased.

摘要： PROBLEM TO BE SOLVED: To miniaturize and simplify a rotation type fluid machine for dividing a plurality of cylinder chambers into a high pressure chamber and a low pressure chamber by a blade, respectively.
SOLUTION: A C-shaped piston 21 is arranged in the annular cylinder chamber, and an outer side cylinder chamber C1 and an inner side cylinder chamber C2 are formed in the inside of a cylinder 17. The blade 27 passes through a cut part of the piston 21 and divides each cylinder chamber C1, C2 into the high pressure chamber and the low pressure chamber. Both end faces of the blade 27 come into slide-contact with wall faces of each circular arc channel 25, 26, and both side faces of the blade 27 come into slide-contact with both end faces of the piston 21. When the cylinder 17 rotates eccentrically for the piston 21, the cylinder 17 advances and retracts for the piston 21 and swings for the blade 27. As a result, volume of each cylinder chamber C1, C2 is expanded and contracted.
