    • Scroll compressors (100, 110) may include a movable scroll (20) that is disposed opposite to a fixed scroll (2). At least one compression chamber (32) is defined between the fixed scroll and the movable scroll. A motor (49) drives the movable scroll, so that the movable scroll revolves (orbits) relative to the fixed scroll. The movable scroll includes a front portion (20b) that slidably contacts the fixed scroll. The front portion receives the pressure of the pressurized refrigerant that is disposed within the compression chamber. The movable scroll also includes a rear portion (20a) that slidably contacts a portion (4a) of a compressor housing. The motor is disposed within a motor chamber (45) defined within the compressor housing. A first conduct route (94) communicates discharged refrigerant from a discharge-side region (85) to the motor chamber. A second conduct route (97, CL) communicates refrigerant from the motor chamber to a suction-side region (98), thereby adjusting the pressure within the motor chamber, so that the opposing pressing forces applied against both sides to the movable scroll can be appropriately adjusted in order to improve compressor efficiency.
    • 涡旋式压缩机(100,110)可包括与固定涡旋件(2)相对设置的动涡旋盘(20)。 至少一个压缩室(32)被限定在固定涡旋件和动涡旋件之间。 马达(49)驱动动涡旋盘,使得动涡旋盘相对于固定涡旋件旋转(轨道)。 动涡旋盘包括可滑动地接触固定涡旋件的前部(20b)。 前部接受设置在压缩室内的加压制冷剂的压力。 动涡旋件还包括可滑动地接触压缩机壳体的部分(4a)的后部(20a)。 电动机设置在限定在压缩机壳体内的电动机室(45)内。 第一行进路线94将排出的制冷剂从排出侧区域(85)传递到电动机室。 第二行进路线(97,CL)将来自马达室的制冷剂与吸入侧区域(98)连通,从而调节马达室内的压力,使得向动涡旋盘两侧施加的相反的挤压力可以是 适当调整以提高压缩机效率。
