Abstract
A scroll compressor having a back pressure discharge is provided. The scroll compressor may include a casing, a discharge cover, a main frame, a first scroll supported by the main frame, and a second scroll forming at least a discharge chamber together with the first scroll. The second scroll may include a discharge opening through which an operation fluid may be discharged. The scroll compressor may also include a back pressure chamber assembly fastened to the second scroll with a Efastener, a back pressure discharge opening that communicates with the back pressure chamber, and a discharge path by which the discharge chamber and the discharge space communicate with each other. The scroll compressor may further include a check valve disposed at the back pressure discharge opening to prevent the operation fluid from being introduced into the back pressure chamber.
