Scroll compressor

A scroll compressor, comprising:

• a casing comprising a rotational shaft;
• a discharge cover fixed inside the casing to partition the inside of the casing into a suction space and a discharge space;
• a first scroll comprising a first wrap that is revolved by rotation of the rotational shaft;
• a second scroll comprising a second wrap that defines a plurality of compression chambers together with the first wrap, the second scroll having an intermediate pressure discharge hole that communicates with a compression chamber having an intermediate pressure of the plurality of 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 movably disposed on or at a side of the back pressure plate to define the back pressure chamber together with the back pressure plate;
• and
• an elastic member that provides an elastic force to press the second scroll to reduce an occurrence of a gap between an end of the first wrap and the second scroll while the refrigerant is compressed.

• a floating plate movably disposed on or at a side of the back pressure plate to define the back pressure chamber together with the back pressure plate, wherein the floating plate comprises a rib that contacts the discharge cover;
• and
• an elastic member that provides an elastic force that moves the floating plate in a direction away from the discharge cover to the floating plate to reduce noise generated when the rib of the floating plate collides with the discharge cover while the refrigerant is compressed.
