涡旋压缩机属一种容积式压缩的压缩机，压缩部件由动涡旋盘和静涡旋组成。
The scroll compressor is a kind of positive displacement compressor. The compressor consists of a moving scroll and a static scroll.
包括使通过压缩机壳体的气体的分路流动方式以减少夹带的油的许多结构特征。在进入壳体之后，某些气体向上流动以减少了向下朝向油的流动的气体量。为了实现这目的，压缩机的电动机可以被套筒包围，该套筒具有用于引导气流到达电动机的上和下定子端部诸匝线圈的上和下孔。在某些实施例中，相对于在定子与电动机壳体之间的两气体通道重要地对吸入进口定位。该进口的位置使一通道接纳进入气体和将该流动分为沿两相反方向即向上和向下的流动。其它的通道仅传送气体向上。此外，吸入挡板、扩散件、流线型平衡重块和/或吸入管捕油件也能有助于气油分离或使夹带的油最少。
Many of the structural features include a shunt flow of gas through the compressor housing to reduce entrained oil. After entering the housing, some gases flow upward to reduce the amount of gas that flows downward toward the oil. In order to achieve this, the motor of the compressor can be surrounded by a sleeve which has upper and lower holes for guiding air flow to the coils at the upper and lower stator ends of the motor. In some embodiments, the suction inlet is positioned relative to the two gas channels between the stator and the motor housing. The position of the inlet allows a channel to receive the incoming gas and divides the flow into two opposite directions, upward and downward. Other channels only send gas up. In addition, suction baffles, diffusers, streamlined counterweights, and / or suction line traps can also help to separate or minimize entrained oil.
