Scroll compressor

A scroll compressor, comprising:

• a casing comprising a rotational shaft;
• a discharge cover fixed inside of the casing to partition the inside of the casing into a suction space and a discharge space;
• a first scroll that is revolved by rotation of the rotational shaft;
• a second scroll that defines 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 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, the floating plate comprising a contact capable of contacting the discharge cover;
• a coating layer that defines an outer surface of the contact;
• and
• an impact absorption layer disposed on a portion of the discharge cover that faces the contact.

A scroll compressor, comprising:

• a casing comprising a rotational shaft;
• a discharge cover fixed inside of the casing to partition the inside of the casing into a suction space and a discharge space;
• an orbiting scroll that is revolved by rotation of the rotational shaft;
• a fixed scroll that defines a plurality of compression chambers together with the orbiting scroll, the fixed 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, the floating plate comprising a rib capable of contacting the discharge cover, wherein the rib is disposed at an upper surface of the floating plate;
• and
• a coating layer provided at an outer surface of the rib, wherein the discharge cover has a first hardness value, the floating plate has a second hardness value, and the coating layer has a third hardness value, and wherein the third hardness value is less than the first hardness value and greater than the second hardness value.
