Abstract
A scroll compressor is disclosed. The scroll compressor may include a back pressure hole formed through a non-orbiting scroll and a back pressure chamber assembly such that a compression chamber and a back pressure chamber communicate with each other. A back pressure valve may be disposed inside of the back pressure hole and move along a longitudinal direction of the back pressure hole by a pressure difference between the compression chamber and the back pressure chamber, to vary a flow path area of the back pressure hole. The back pressure valve may include a valve body that extends in an axial direction and a plurality of holes formed through the valve body in the axial direction. With the configuration, pressure pulsation in the back pressure chamber may be suppressed or prevented.
