Abstract: A scroll compressor is provided, the scroll compressor having a block insertion groove recessed by a predetermined depth into a rear surface of a non-orbiting scroll to accommodate a discharge port and a plurality of bypass holes, and a retainer block having a bypass valve that opens and closes the plurality of bypass holes fixedly inserted into the block insertion groove. The bypass valve may be fixed to a first axial side surface of the retainer block facing the block insertion groove. Through this, the bypass valve that suppresses or prevents overcompression of a compression chamber is not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be reduced in thickness. This may shorten lengths of the plurality of bypass holes and the discharge port by the reduced thickness of the non-orbiting end plate, thereby decreasing a dead volume in the plurality of bypass holes and the discharge port.

Abstract: A scroll compressor may include a block insertion groove recessed by a predetermined depth into a rear surface of a non-orbiting scroll to accommodate a discharge port and at least one bypass hole, and a retainer block having at least one bypass valve to open and close the at least one bypass hole may be fixedly inserted into the block insertion groove. Accordingly, the at least one bypass valve that suppresses or prevents overcompression in a compression chamber is not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be formed thin. As the non-orbiting end plate is reduced in thickness, a length of the at least one bypass hole may be reduced, thereby decreasing a dead volume in the at least one bypass hole.

Abstract: A scroll compressor is provided that may include a block insertion groove to accommodate a discharge port and at least one bypass hole disposed in a rear surface of a non-orbiting end plate of a non-orbiting scroll, and a retainer block including at least one bypass valve to open or close the bypass hole inserted into the block insertion groove. The bypass hole may include a first bypass hole and a second bypass hole. The bypass valve may include a first bypass valve to open or close the first bypass hole and a second bypass valve to open or close the second bypass hole, and may be disposed between the block insertion groove and the retainer block facing the block insertion groove. Accordingly, the first and second bypass valves are not fastened to the non-orbiting end plate, which may allow the non-orbiting end plate to be made thin.

Abstract: A compressor may include a casing; an electric motor provided in the casing and that operates a rotational shaft; and a compression device. A flow path guide may be installed between the electric motor and the compression device, and may separate a refrigerant flow path from an oil flow path. The flow path guide may have a first partition wall and a second partition wall which are spaced apart from each other. In addition, the flow path guide may have an oil discharge port formed in at least a section of the flow path guide along a circumferential direction thereof, the oil discharge port allowing a guide space between the first partition wall and the second partition wall to be open toward the inner surface of the casing.

Abstract: A compressor is provided having an integrated flow path structure in which an oil flow path and an intermediate pressure flow path are integrated into one in a compression unit, thereby simplifying a flow path of the compression unit. The compressor may include at least one integrated flow path in which the oil flow path and the refrigerant gas flow are integrated into one in a fixed scroll. The at least one integrated flow path may connect an intermediate pressure chamber and a compression chamber in a compressors unit. The at least one integrated flow path may provide a compressed refrigerant in the compression chamber to the intermediate pressure chamber and provide oil in the intermediate pressure chamber to the compression chamber, simplifying the flow path of the compression unit.

Abstract: A scroll compressor is provided. In the scroll compressor, a valve accommodating groove that accommodates a discharge port and bypass holes is recessed by a predetermined depth into a rear surface of a non-orbiting scroll, and a valve guide is disposed between the rear surface of the non-orbiting scroll and a rear surface of the back pressure chamber assembly facing the rear surface of the non-orbiting scroll. Bypass valve guide holes into which bypass valves that open and close the bypass holes are slidably inserted are formed in the valve guide. Accordingly, the bypass valves that suppress or prevent overcompression in compression chambers are not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be reduced in thickness. As the non-orbiting end plate is reduced in thickness, lengths of the bypass holes may be reduced, thereby decreasing dead volumes in the bypass holes.

Abstract: A scroll compressor is provided that may include a casing, a drive motor, an orbiting scroll, a non-orbiting scroll, and a floating plate provided with a cover portion to cover an area between an outer wall portion and an inner wall portion of the non-orbiting scroll so as to form a back pressure chamber with the non-orbiting scroll, and a valve accommodating portion that extends from the cover portion so as to accommodate a discharge valve configured to open and close a discharge port. Accordingly, structure for forming a back pressure chamber is simplified to thereby reduce the number of components and man-hours required for assembly.

Abstract: A scroll compressor is disclosed. The scroll compressor may include a back pressure hole formed through a non-orbiting scroll and a back pressure chamber assembly such that a compression chamber and a back pressure chamber communicate with each other. A back pressure valve may be disposed inside of the back pressure hole and move along a longitudinal direction of the back pressure hole by a pressure difference between the compression chamber and the back pressure chamber, to vary a flow path area of the back pressure hole. The back pressure valve may include a valve body that extends in an axial direction and a plurality of holes formed through the valve body in the axial direction. With the configuration, pressure pulsation in the back pressure chamber may be suppressed or prevented.
