Abstract
A scroll compressor is provided. The scroll compressor may include a casing, a discharge cover to partition an inside of the casing into suction and discharge spaces, a first scroll, a second scroll that defines compression chambers together with the first scroll and includes an intermediate pressure discharge hole that communicates with a compression chamber having an intermediate pressure of the compression chambers, a back pressure plate that defines a back pressure chamber that accommodates a refrigerant discharged from the intermediate pressure discharge hole, a floating plate that defines the back pressure chamber together with the back pressure plate, and a gasket disposed between the back pressure plate and the second scroll and having an intermediate pressure communication hole that allows the intermediate pressure discharge hole to communicate with the intermediate pressure suction hole. The gasket may block communication between the back pressure chamber and the suction and discharge spaces.
