Abstract

A scroll compressor is provided. The scroll compressor may include a casing including a rotational shaft, a discharge cover fixed at an inside of the casing to partition the inside of the casing into a suction space and a discharge space, a first scroll rotated by the rotational shaft to perform an orbiting motion, a second scroll disposed on or at a side of the first scroll to define a plurality of compression chambers together with the first scroll, the second scroll having an intermediate pressure discharge hole that communicates with a compression chamber having an intermediate pressure among the plurality of compression chambers, a back pressure plate coupled to the second scroll, the back pressure plate having an intermediate pressure suction hole that communicates with the intermediate pressure discharge hole, a floating plate movably disposed on or at a side of the back pressure plate to define a back pressure chamber together with the back pressure plate, and a discharge guide defined in the first scroll or the second scroll to guide discharge of a refrigerant within the back pressure chamber.
