PURPOSE: A scroll compressor is provided to relieve the impact which is generating between the center hole and bushing projection by having a cushion ring of the elastic material in the center hole formed in the head unit of a driving shaft. CONSTITUTION: A scroll compressor comprises a housing, a fixed scroll, an orbiting scroll, and an operating unit. The housing has the motor unit offering the rotation power to the inside. The fixed scroll is fixed to the front of the housing and is installed. As the rolling scroll is rotated eccentrically, the refrigerant compression space in which volume changes is formed between the fixed scroll. The operating unit comprises a driving shaft(40), a scroll bushing(60), and a balance weight. The operating unit transfers the rotation power of the motor unit to the rolling scroll. The driving shaft forms the center hole(43) at the leading end center. The scroll bushing forms the bushing projection(63) inserted into the center hole. The inner diameter of the center hole has the big value than the diameter of the bushing projection. The buffer ring(45) of the elastic material is installed between the inner diameter of the center hole and outer diameter of the bushing projection. |
