A scroll compressor including a fixed scroll including a wrap accommodation portion having an inner space extending inside the wrap accommodation portion, a thrust surface around the inner space, a fixed wrap in the inner space, and an oil groove on the thrust surface; an orbiting scroll to rotate with respect to the fixed scroll, and including a mirror plate, an orbiting wrap extending from the mirror plate to engage with the fixed wrap, and at least one oil supply groove on the mirror plate facing the thrust surface of the fixed scroll; and a driving motor to rotate the orbiting scroll. When the orbiting scroll rotates, the at least one oil supply groove of the orbiting scroll moves from a first position to receive oil from the oil groove, to a second position to supply the oil to the inner space of the wrap accommodation portion.

Scroll compressor with oil supply groove

A scroll compressor including a fixed scroll including a fixed wrap, an orbiting scroll including an orbiting wrap facing the fixed scroll to form a compression chamber together with the fixed wrap, and a first receiving groove formed on a second surface, opposite to the orbiting wrap, a frame including a second receiving groove formed on a surface facing the second surface of the orbiting scroll and forming a ring-shaped chamber disposed inside the frame and between the second surface and the surface of the frame, a guide ring disposed in the ring-shaped chamber, and a plurality of roller bearings each including an inner ring fixed to the guide ring, wherein some of the roller bearings are disposed in the first receiving groove and others are disposed in the second receiving groove, and the guide ring and the plurality of roller bearings prevent the orbiting scroll from rotating.

Scroll compressor and home appliance including the same

Provided is a scroll compressor with enhanced sealing structure of a back pressure chamber. The scroll compressor includes a housing, a fixed scroll fixed to inside of the housing and including a fixed wrap, an orbit scroll including an orbit wrap which forms a compression chamber together with the fixed wrap, a back pressure chamber formed at a frame supporting the orbit scroll, and accommodating refrigerant for pressurizing the orbit scroll to a direction of the fixed scroll, and a sealing ring arranged between the fixed scroll and the orbit scroll to prevent the refrigerant in the back pressure chamber from flowing in or out through a gap between the fixed scroll and the orbit scroll, wherein the sealing ring includes a cut portion cut for the sealing ring to be deformable in a circumferential direction.

Scroll compressor

A scroll compressor includes a main body, a cover to divide the main body into a low pressure section and a high pressure section, a fixed scroll including a first discharge port, an orbiting scroll to rotate with respect to the fixed scroll and to form a compression chamber together with the fixed scroll, a discharge guide disposed between the fixed scroll and the cover and including a second discharge port connected to the first discharge port, and a back pressure actuator configured to form a back pressure chamber together with the discharge guide and to move in a direction toward the cover with respect to the discharge guide to selectively connect the second discharge port with the high pressure section. The fixed scroll includes a bypass flow path connecting the compression chamber and the second discharge port and a bypass valve to open or close the bypass flow path.

A compressor including a compression unit comprising an inlet for sucking gas and configured to compress the sucked gas; and a casing configured to accommodate the compression unit; and a suction guide comprising a passage for guiding the gas from an outside of the casing to the inlet. The compression unit includes a first surface extending from an edge of the inlet, the suction guide includes a second surface extending from an edge of a vent of the passage, and provided in an internal area of the casing to make the first surface and the second surface face each other, and an external end of the first surface and an internal end of the second surface or an internal end of the first surface and an external end of the second surface do not overlap along a direction of an axis of the compressor.
