    • A variable capacity compressor for refrigeration systems such as air conditioners and heat pumps comprising an outer casing having a lubricant sump in the lower portion thereof, a crankcase internally spring mounted within the outer casing and having a pair of parallel, vertical crankshafts rotatably supported therein, wherein the crankshafts are arranged in side-by-side relationship, and at least two expansible chamber pumps, which may be piston, rotary or screw type, driven by the crankshafts. A pair of independently controlled electric motors have their rotors drivingly connected to the crankshafts, and in one embodiment of the invention, the motors have a common stator with two independently controlled sets of windings. In a further embodiment of the invention, two crankcases are provided, sharing a common lubricant sump.
    • 一种用于诸如空调和热泵的制冷系统的可变容量压缩机,包括在其下部具有润滑油槽的外壳,内部弹簧安装在外壳内并具有可旋转地支撑在其中的一对平行的竖直曲轴, 其中曲轴以并排的关系布置,并且至少两个可由活塞,旋转或螺旋式的可膨胀室泵由曲轴驱动。 一对独立控制的电动机的转子驱动地连接到曲轴上,并且在本发明的一个实施例中,电动机具有共同的定子,其具有两个独立控制的绕组组。 在本发明的另一实施例中,提供两个曲轴箱,共用一个普通的润滑油槽。
