Abstract: A scroll compressor including a housing, a motor in the housing, an orbiting scroll, and a fixed scroll. An injection valve assembly is provided between the fixed scroll and the housing and further includes a cover plate, a valve plate, a gasket retainer, and an injection valve. The compressor capable of increasing a surface pressure at a position at which the injection valve of the injection valve assembly needs to be supported, and preventing deformation of the gasket retainer by reducing a bead height of the gasket retainer.

Abstract: A scroll compressor capable of improving the performance and efficiency of the compressor by increasing the amount of refrigerant discharged from a compression chamber by introducing not only refrigerant at suction pressure but also refrigerant at an intermediate pressure to the compression chamber of the scroll compressor, capable of freely changing the position of a port by simplifying the shape of an injection valve assembly and by disposing a fastening member on an introduction chamber side, and capable of compactifying the injection valve assembly.

Abstract: A scroll compressor including: a housing; a motor provided in the housing; a rotary shaft configured to be rotated by the motor; an orbiting scroll configured to orbit in conjunction with the rotary shaft; and a fixed scroll configured to define compression chambers together with the orbiting scroll, in which the housing includes: a center housing penetrated by the rotary shaft; a front housing configured to define a motor accommodation space that accommodates the motor; and a rear housing configured to define a discharge chamber for accommodating a refrigerant discharged from the compression chambers, and an introduction chamber for accommodating a middle-pressure refrigerant introduced from the outside of the housing, in which the fixed scroll has a plurality of injection ports that guides the refrigerant in the introduction chamber to the compression chambers.
