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 swash plate compressor including: a housing; a rotating shaft rotatably mounted to the housing; a swash plate accommodated in a crank chamber of the housing and rotating with the rotating shaft; a piston forming a compression chamber with the housing and interlocking with the swash plate to reciprocate; a discharge flow path guiding a refrigerant of the crank chamber to a suction chamber of the housing wherein an inclination angle of the swash plate is adjusted; and a discharge flow path control valve having a valve chamber provided in the discharge flow path and a valve core reciprocating inside the valve chamber, and the valve core includes: a first communication path constantly communicating the discharge flow path; and a second communication path communicating the discharge flow path when differential pressure between pressure of the crank chamber and pressure of the suction chamber is within a certain pressure range.

Abstract: A compressor including: a casing; a rotary shaft rotatably mounted in the casing; a compression mechanism configured to compress a refrigerant by operating in conjunction with the rotary shaft; a thrust plate configured to support an end surface of the rotary shaft; a chamber configured to accommodate the thrust plate; and a slit configured to guide oil to the chamber, in which a part of the slit is formed to face a contact portion between the rotary shaft and the thrust plate, such that it is possible to supply the oil between the rotary shaft and the thrust plate, thereby preventing damage to the thrust plate for supporting the rotary shaft. In addition, an inner diameter of the chamber gradually increases, and the chamber extends to an end surface of a cylinder block, such that the cylinder block may be easily extracted from a mold.

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.
