Abstract: A scroll compressor (10) with a fixed scroll (18) and orbital scroll (20) has an axial thrust and anti-rotation assembly (22), a drive assembly (24), a balance assembly (26) and a control system (28). The drive assembly (24) includes a crankshaft (116) and a bushing assembly (108). The bushing assembly includes a bushing body (146) with a slot (154) journaled on the orbital scroll and a drive lug (150) positioned in the slot and non-rotatably secured to the crankshaft. Springs (156) bias the bushing body toward a position in which the axis of the bushing body (178) coincides with the axis (176) of the crankshaft (116) and the crankshaft can rotate without moving the orbital scroll (20). The bushing body can be moved by compressed fluid to a position in which the springs are compressed, the scroll wraps (34 and 56) are in sealing contact and the drive assembly will drive the orbital scroll (20) in a circular orbit with a radius R.sub.o. The balance assembly includes two weight assemblies (184 and 186) with four weights (192, 196, 210 and 214) that are rotated about the axis of cylindrical extension (182) in response to movement of the drive lug (150) relative to the bushing body (146) between a position in which the orbital scroll is balanced and a position in which the weights balance themselves when the crankshaft rotates without driving the orbital scroll. The control system includes a trigger compressor (242) and a solenoid valve (246) which directs compressed fluid to the sump (88) when the valve is open and to the chamber (162) in the bushing assembly when the valve is closed.

Abstract: A wobble plate compressor which is adapted to vary the angularity of the wobble plate during rotation in response to the difference between the resultant reaction force exerted by the pistons on their compression and suction strokes and the pressure in the crankcase. The wobble plate is supported by a first fulcrum movable along the drive shaft around which it is disposed, at a diametrically central location, and by a second fulcrum at a location radially spaced from the drive shaft. The second fulcrum is formed by an end of an arm member disposed for rotation together with the drive shaft. The above end of the arm member is in camming engagement with a side surface of the wobble plate so that with an increase in the angularity of the wobble plate the second fulcrum moves toward the axis of the drive shaft through a substantial stroke, whereby the angularity of the wobble plate can vary at a reduced rate relative to a change in the pressure in the crankcase, thereby enhancing the stability of capacity control.

Abstract translation: 一种摆盘式压缩机，其适于在旋转期间响应于由活塞在其压缩和吸入冲程上产生的反作用力与曲轴箱中的压力之间的差异来改变摆盘的角度。 摆动板由沿着驱动轴的第一支点支撑，第一支点在径向中心位置处设置，并且在与驱动轴径向间隔开的位置处由第二支点支撑。 第二支点由设置成与驱动轴一起旋转的臂构件的端部形成。 臂构件的上端与摆盘的侧面凸轮啮合，从而随着摆盘的角度的增加，第二支点大致行程向驱动轴的轴线移动，由此， 摆动板的相对于曲轴箱中的压力变化的速率可以变化，从而提高容量控制的稳定性。
