Abstract
A compressor includes a housing, a motor disposed in the housing, a driving shaft connected to the motor, a first compression mechanism connected to the driving shaft, and a second compression mechanism. The second compression mechanism includes a stationary scroll and an orbiting scroll engaged with each other, a bushing seat positioned at an end portion of the driving shaft, a bushing, and a bearing. A main axis of the driving shaft passes through a positioning protrusion of the bushing seat, and the positioning protrusion is deflected at an angle relative to a straight line connected by a plurality of contact points between the orbiting scroll and the stationary scroll. The bushing is sleeved on the positioning protrusion, and a center line of the bushing is eccentric to the main axis. The bearing is sleeved on the bushing, and the orbiting scroll is sleeved on the bearing.
