摘要： PROBLEM TO BE SOLVED: To solve a problem that when a motor side end of a main bearing rotatably supporting a rotating shaft is formed in a tapered face and a tapered face is set also on the opposite rotating shaft, a motor shaft part which is a motor part of the rotating shaft has to have a smaller diameter than the tapered face on the bearing side and the shaft rigidity is lowered. SOLUTION: A shaft-fixed separate member having a tapered face of a larger diameter than the rotating shaft is fixedly arranged on a rotating shaft part passed through the main bearing, and a tapered face of a larger diameter than the rotating shaft is equipped on a rotating shaft part not passed through the main bearing. With this, the inclination of the rotating shaft is lessened and uneven contact of the bearing is lessened so that bearing loss is reduced and the bearing reliability is enhanced. Further, motor efficiency is improved by equalization of a motor gap. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To enhance the efficiency of a scroll compressor by stabilizing the pressure of a back pressure chamber provided on the back surface of a scroll member to thereby reduce the fluctuation of a biasing force for biasing one scroll member to the other scroll member. SOLUTION: A compression chamber-side communicating port of a back pressure communicating passage is provided in a position of the tooth bottom of one scroll member such that it faces compression chambers of both systems, and has a tooth shape such that the compression of the compression chamber formed by the inner line of the scroll member including the compression chamber-side communicating port is preferentially started. According to this, the pressure fluctuation width of the compression chambers communicating with the compression chamber-side communicating port is reduced, and the fluctuation width of back pressure associated therewith is also reduced. Since deformation fluctuation of the scroll members is suppressed by this suppression of back pressure fluctuation, the overall heat-insulating efficiency can be improved by reduction in leak loss by improvement in sealing property in a gap between both the scroll members and reduction in friction loss by suppression of mutual interference thereof allows improvement.

摘要翻译：要解决的问题：为了通过稳定设置在涡旋构件的背面上的背压室的压力来提高涡旋压缩机的效率，从而减小用于将一个涡旋构件偏压到其他滚动成员。解决方案：背压连通通道的压缩室侧连通口设置在一个涡旋构件的齿底的位置，使其面对两个系统的压缩室，并且具有齿形，使得压缩由包括压缩室侧连通口的涡旋构件的内部线形成的压缩室优先开始。因此，与压缩室侧连通口连通的压缩室的压力波动宽度减小，与此相关联的背压的波动宽度也降低。由于通过这种背压波动的抑制来抑制涡旋件的变形波动，所以通过改善两个涡旋件之间的间隙中的密封性能以及通过减小摩擦损失来减小摩擦损失，可以减少泄漏损失，从而可以提高整体的隔热效率抑制其相互干扰允许改进。版权所有（C）2011，JPO＆INPIT
