The invention relates to a variable capacity compressor. The compressor comprises a housing, a variable capacity cylinder and a lower flange assembly arranged below the variable capacity cylinder; thelower flange assembly is provided with a sliding hole communicating with a variable capacity chamber of the variable capacity cylinder, and the sliding hole is provided with a locking assembly that can be reciprocable in the axial direction thereof and lock a variable capacity sliding plate of the variable capacity cylinder; upper part of the locking assembly is communicated with lower part of the locking assembly through the variable capacity chamber and a variable capacity channel and with a constant pressure passage arranged on the housing. By adjusting air pressure values of the variablecapacity passage and the constant pressure passage, the variable capacity sliding plate can adhere to a lower roller under variable light operating conditions and under the action of high back pressure, which reduces fluctuation of the capacity and ticking sound; meanwhile, by reducing pressure difference between the variable capacity passage and the constant pressure passage, gas leakage from topto bottom of the locking assembly can be reduced, which reduces the impact and friction between the locking component and other components during state switching, thereby improving cooling efficiencyand cooling capacity as a whole, and increasing compressor reliability.
