Abstract
A scroll compressor is provided. The scroll compressor comprises a main frame provided between a first compression unit and a second compression unit, and the main frame may comprise at least one back pressure communication unit communicating between a first back pressure chamber and a second back pressure chamber. Accordingly, even if the back pressure of the first back pressure chamber and/or the second back pressure chamber rises above a set pressure when the compressor is started, the pressure in a back pressure chamber with a relatively high back pressure is transferred to a back pressure chamber with a relatively low back pressure, thereby enabling both back pressure chambers to quickly recover an appropriate level of back pressure while suppressing friction loss and dissipation in the compression unit, and at the same time suppressing leakage between compression chambers to increase compression efficiency.
