    • A scroll-type compressor for realizing the operating condition of complete 0% capacity without using an electromagnetic clutch. In order to minimize the power loss, a compliance crankshaft mechanism for allowing the orbiting radius of the movable scroll member to change steplessly to zero is interposed between a shaft and a scroll member. A guide hole having an inclined surface such as a two-step conical surface is formed at the end plate of the movable scroll member. A plunger adapted to engage by advancing toward and retracting from the guide hole is supported on a housing. When the plunger is advanced into the guide hole under the control of a control operation device including a control pressure chamber and a control valve, the movable scroll member moves radially, so that the amount of eccentricity and the orbiting radius thereof are reduced to achieve the 0% capacity.
    • 一种用于在不使用电磁离合器的情况下实现完全0%容量的操作条件的涡旋式压缩机。 为了使功率损失最小化,可以在轴和涡旋构件之间插入用于使可动涡旋构件的旋转半径无级变更为零的顺应性曲轴机构。 在可动涡旋件的端板处形成具有诸如两级锥形表面的倾斜表面的导向孔。 适于通过朝向导向孔前进和后退而接合的柱塞被支撑在壳体上。 当在包括控制压力室和控制阀的控制操作装置的控制下柱塞进入引导孔时,可动涡旋件径向地移动,使得偏心量和其绕行半径减小以达到 0%容量。
