    • 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。

    • A self-rotation blocking mechanism in a scroll compressor having a movable scroll member and fixed scroll member fixed to a casing. The mechanism is constructed of circumferentially spaced opposing pairs of pins 9 and 10, which are connected to an end plate 12 of the movable scroll member 2 and a faced end wall of the casing 4, respectively, and which are in a side-by-side contacting relationship. The circumferential arrangement of the pins is such that, at every angular position of the movable scroll member, there exists at least one pair of the pins which generates a force in a direction opposite to a self-rotating torque applied to the movable scroll member caused by the compression reaction force. A locally concentrated arrangement of the pairs of the pins for generating such a force can be employed at the angular position which produces a larger value of self-rotating torque. Furthermore, the diameters of the pins are such that one half of the sum of the diameters is equal to or smaller than the radius of the orbital movement of the movable scroll member.
    • 一种涡旋压缩机中的自旋转阻塞机构,其具有固定在壳体上的可动涡旋部件和固定涡旋部件。 该机构由周向间隔开的相对的销9和10构成,销对9和10分别连接到可动涡旋件2的端板12和壳体4的相对的端壁, 侧面接触关系。 销的圆周布置使得在可动涡旋构件的每个角位置处存在至少一对销,其在与施加到动涡旋件的自转转矩相反的方向上产生力,引起 通过压缩反作用力。 可以在产生较大的自转转矩值的角位置采用用于产生这种力的销对的局部集中布置。 此外,销的直径使得直径之和的一半等于或小于可动涡旋件的轨道运动的半径。
