摘要： A multi-cylinder rotary compressor (100) includes a plurality of compression mechanism parts (a first compression mechanism part (10) and a second compression mechanism part (20)). A drawing force is applied to a vane of at least one of the compression mechanism parts radially outward with respect to a drive shaft so that a pressing force of pressing the vane toward a piston is smaller than those in the other compression mechanism parts. In a normal state, a pressing force due to a gas pressure difference between a suction pressure and a discharge pressure is larger than the drawing force, and a front end of the vane is pressed against a rotary piston peripheral wall so that a compression operation is performed. On the other hand, when the drawing force becomes greater than the pressing force, the front end of the vane is automatically moves to be separated from the rotary piston peripheral wall with a communication space through which oil is introduced from a sealed container to a rear space of the vane being in a discharge pressure state and the front end of the vane being in a suction pressure state. Then, when the front end of the vane is separated from the rotary piston to a predetermined distance or more, a significant step function change of the difference between the drawing force and the pressing force occurs, a retention mechanism stably retains the vane at a location separated from the piston, and the compression mechanism part switches to an uncompressed state.
摘要翻译：多缸旋转压缩机100包括多个压缩机构部（第一压缩机构部10和第二压缩机构部20）。对于至少一个压缩机构部件的叶片相对于驱动轴径向向外施加拉力，使得将叶片向活塞推压的压力小于其它压缩机构部件中的压力。在正常状态下，由于吸入压力和排出压力之间的气体压力差引起的按压力大于拉拔力，并且叶片的前端被压靠在旋转活塞周壁上，使得压缩操作执行。另一方面，当牵引力变得大于按压力时，叶片的前端自动地移动以与旋转活塞周壁分离，具有连通空间，油通过该连通空间从密封容器引入到后部叶片的空间处于排出压力状态，叶片的前端处于吸入压力状态。然后，当叶片的前端与旋转活塞分离到一定距离以上时，产生牵引力和压力之间的差异的显着的阶梯函数变化，保持机构将叶片稳定地保持在位置与活塞分离，并且压缩机构部分切换到未压缩状态。

摘要： A vane-type compressor (200) includes a rotor shaft (4) that includes rotating shaft portions (4b and 4c) and a rotor portion (4a), which are integrated with one another. A lower end of the rotating shaft (4c) is disposed in an oil reservoir (104). The vane-type compressor (200) also includes vane aligners (5 to 8) disposed at both end portions of vanes (9 and 10), and recess portions (2a and 3a), which are respectively formed in a frame (2) and a cylinder head (3) so as to be concentric with an inner circumferential surface (1b) of a cylinder (1). Outer circumferential surfaces of the vane aligners (5 to 8) are slidably supported by the recess portions (2a and 3a). In the rotor shaft (4), oil supply channels (4h, 4i, and 4j), which allow communication between the oil reservoir (104) and the recess portions (2a and 3a) of the frame (2) and the cylinder head (3), and an oil pump( 31), which supplies refrigerating machine oil (25)in the oil reservoir (104) to the oil supply channels, are provided.
