Abstract: A scroll compressor is described. The scroll compressor comprises a case having a high-pressure side and a low-pressure side, a stationary scroll plate having a base plate with a first side having at least one projection, which forms a spiral wrap, and a second side having a first annular protrusion, a pilot plate for separating the high-pressure side of the case from the low-pressure side of the case and the pilot plate abutting the second side of the stationary scroll plate, wherein the pilot plate has a first side, wherein the first side faces the second side of the stationary scroll plate and wherein the first side has a second annular protrusion, and a seal, wherein the seal seals a radial gap between the first annular protrusion and the second annular protrusion.

Abstract: A scroll plate for use in a scroll compressor is described. The scroll plate comprises a base plate having a first side and a second side, wherein the second side opposes the first side, and a spiral wrap formed on the first side of the base plate, wherein the base plate comprises one or more recesses and wherein an insulating material is located in at least one of the one or more recesses. Further, a scroll compressor having a corresponding scroll plate is described.

Abstract: A stationary scroll plate for use in a scroll compressor is described. The stationary scroll plate comprises a base plate having a first side and a second side, wherein the second side opposes the first side; a spiral wrap formed at the first side of the base plate, wherein the spiral wrap is adapted to interact with a corresponding spiral wrap of an orbiting scroll plate to form a compression chamber; an injection channel formed within the base plate, the injection channel providing an injection path for injection of fluid into the compression chamber; a recess located at the second side; an insert placed within the recess, wherein the insert forms a cooling chamber within the recess; an inlet channel via which the cooling chamber is connected to the injection channel; and an outlet channel via which the cooling chamber is connected to the inside of the spiral wrap.
