Abstract
A scroll compressor is disclosed. The scroll compressor has back pressure holes which are formed in a non-orbiting scroll and a back pressure chamber assembly, and provide communication between a compression chamber and a back pressure chamber. In addition, a back pressure valve is provided inside of the back pressure hole to change a passage area of the back pressure hole by moving along a longitudinal direction of the back pressure hole due to a pressure difference between the compression chamber and the back pressure chamber. Due to the back pressure valve, pressure pulsation in the back pressure chamber may be improved.
