ELECTRICALLY DRIVEN SCROLL COMPRESSOR

摘要

The present invention relates to an electrically driven scroll compressor. The electrically driven scroll compressor includes a housing into and from which a refrigerant is introduced and discharged, a driving part disposed within the housing to generate a rotation force of a driving shaft, an orbiting scroll rotated by the driving part, a scroll compression part including a fixed scroll to compress the refrigerant, wherein the fixed scroll and the orbiting scroll define a compression space therebetween, and a sliding bush disposed between the driving shaft and the orbiting scroll to eccentrically rotate with respect to the rotation of the driving shaft, the sliding bush transmitting the rotation force of the driving shaft to the orbiting scroll. An oil flow passage, through which oil flows, is defined in the housing for lubrication. Also, an inclined portion is disposed on an end in a rotation direction of the sliding bush. The inclined portion is disposed on the oil flow passage. Since a portion of the flowing oil or the entirety of the oil compresses the inclined portion, a moment is applied in a direction opposite that of a moment resulting from the eccentricity of the sliding bush. Thus, according to the present invention, tilting can be reduced to prevent the partial abrasion of the sliding bush and of a sliding bearing, thereby improving the lifespan of the compressor. In addition, the electrically driven scroll compressor can be stably operated, and resistance against oil can be reduced to reduce power consumption.
