Compressor

A compressor, comprising:

• a housing, having a first compression chamber and a second compression chamber that are communicated with each other;
• a motor, disposed in the housing;
• a driving shaft, connected to the motor, wherein the driving shaft passes through the first compression chamber and extends into the second compression chamber;
• a first compression mechanism, disposed in the first compression chamber, and connected to the driving shaft;
• and
• a second compression mechanism, disposed in the second compression chamber, and comprising:
• a stationary scroll;
• an orbiting scroll, engaged with the stationary scroll, wherein there are a plurality of contact points between the orbiting scroll and the stationary scroll to form a plurality of compression spaces;
• a bushing seat, positioned at an end portion of the driving shaft, and having a positioning protrusion, wherein a main axis of the driving shaft passes through the positioning protrusion, and the positioning protrusion is deflected at an angle relative to a straight line connected by the contact points;
• a bushing, sleeved on the positioning protrusion, wherein a center line of the bushing is eccentric to the main axis and is inclined relative to the main axis;
• and
• a bearing, sleeved on the bushing, wherein the orbiting scroll is sleeved on the bearing,
• wherein the bushing seat has one of:
• A) a first supporting surface and a second supporting surface connected to the first supporting surface, the positioning protrusion protrudes from the first supporting surface and the second supporting surface, there is a height difference between the first supporting surface and the second supporting surface, the bushing is in contact with the first supporting surface and the second supporting surface, or
• B) a supporting slope, the positioning protrusion protrudes from the supporting slope, the bushing is in contact with the supporting slope.
