Abstract: Disclosed herein is a high-pressure scroll compressor, in response to a discharged refrigerant flowing into a back pressure chamber, capable of directly discharging the refrigerant to a space inside a main body, and capable of maintaining an intermediate pressure of the back pressure chamber to be less than a discharge pressure of the refrigerant by separately providing a discharge flow path in the back pressure chamber.

Abstract: A scroll compressor is provided which comprises: a housing; a driving motor; an orbiting scroll rotated by the driving motor; a fixed scroll; a suction port provided in the housing and suctioning a refrigerant; an oil separator in the housing at one side of the fixed scroll; and a discharge port for discharging, to the outside of the housing, the refrigerant from which oil is separated in the oil separator. The scroll compressor includes an intermediate housing; a back pressure chamber in the intermediate housing at one side of the orbiting scroll, first and second back pressure seal members in the intermediate housing; a plurality of anti-rotation rings in the intermediate housing; and a plurality of anti-rotation pins at the orbiting scroll to be inserted into each of the plurality of anti-rotation rings.

Abstract: A variable capacity scroll compressor includes a fixed scroll. The fixed scroll of the compressor includes a bypass flow path configured to connect a suction unit to a compression unit, a cylinder space provided on the bypass flow path, and an on/off valve disposed to be movable back and forth in the cylinder space to open/close the bypass flow path according to a difference between a discharge pressure of the discharge unit and a suction pressure of the suction unit. Thus a capacity of the compressor may be reduced by connecting the suction unit to the compression unit under a low load condition in which a difference between a discharge pressure and a suction pressure is relatively less.

Abstract: Disclosed herein is an a compressor including a main body, a fixed scroll fixed on the inside of the main body, an orbiting scroll arranged to orbit relative to the fixed scroll, a compressing chamber formed by the fixed scroll and the orbiting scroll, an oil supply hole arranged to supply oil to a contact portion formed by the fixed scroll and the orbiting scroll, and an oil groove formed on an inner side of the contact portion to be closed to an outer side of the contact portion. The oil groove is extended into the form of an arc by being rotated by about 270 degrees or more along the circumference of the fixed scroll to cover the compressing chamber from the outside of the compressing chamber to supply oil all across the area of the contact portion easier which leads to more reliable operation of the compressor.

Abstract: Provided is a scroll compressor having an improved structure in which reliability of a compression portion can be enhanced.
