Apparatus for a Formation of Back-Pressure in Electric Compressor and Method Employing the Same

摘要

The present invention exceeds the back pressure formation structure of the electric compressor and a method of applying the same among the technologies related to the electric compressor, and does not use an additional member to form the back pressure, and by forming the back pressure with only one member, the cost is reduced and the A back pressure forming structure capable of improving reliability and a method of applying the same are proposed. In the electric compressor according to the present invention, a back pressure forming member applied to the orbiting scroll while preventing leakage of the back pressure chamber, a first space that is a space for applying the tip thread to the orbiting scroll, and a gap between the orbiting scroll and the tip chamber Including a second space, wherein the back pressure forming member provides a back pressure forming apparatus of the electric compressor including a diameter adjusting portion to change the diameter according to the back pressure formed in the orbiting scroll.
