Abstract: A scroll compressor may include a frame, an orbiting scroll provided with at least one first key groove, a non-orbiting scroll provided with at least one second key groove and coupled to the orbiting scroll to form a compression chamber, and an anti-rotation ring disposed between the frame and the orbiting scroll. The anti-rotation ring may include a ring, at least one first key that axially extends from a first surface of the ring and slidingly coupled to the at least one first key groove of the orbiting scroll, and at least one second key that axially extends from the first surface of the ring and slidingly coupled to the at least one second key groove of the non-orbiting scroll. The first and second keys may be provided along a circumferential direction. This may allow processability of a one-way anti-rotation ring. Further, increase in weight may be prevented while reducing deformation by providing a weight-reduced portion in addition to a reinforcing portion.

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 may include a casing having a low pressure portion and a high pressure portion, a refrigerant suction pipe that communicates with the low pressure portion and a refrigerant discharge pipe that communicates with the high pressure portion, a drive motor installed inside of the low pressure portion, an orbiting scroll coupled to the drive motor to perform an orbiting motion, a non-orbiting scroll engaged with the orbiting scroll to form a compression chamber, and a refrigerant guide provided on the non-orbiting scroll to guide a refrigerant suctioned into the low pressure portion to be suctioned into the compression chamber, whereby an increase in specific volume of refrigerant suctioned into the compression chamber may be suppressed, and thus, an amount of refrigerant suctioned into the compression chamber may increase, thereby improving efficiency of the compressor.

Abstract: A compressor may include a casing, and a compression device installed inside of the casing and that compresses the refrigerant while rotating by receiving a rotational force of an electric motor through a rotational shaft. A high/low pressure separation plate may be installed at an upper portion of the compression device, and an insulation plate may be provided to block the high/low pressure separation plate and the suction tube from each other by being located therebetween. The insulation plate may reduce heat transfer between a refrigerant discharge space having a high temperature located at the upper portion of the high/low pressure separation plate and a refrigerant suction space having a relatively low temperature located at a lower portion of the high/low pressure separation plate.

Abstract: A scroll compressor is provided that may include a frame; a non-orbiting scroll provided with a non-orbiting wrap formed on a first side surface of a non-orbiting end plate in an axial direction; an orbiting scroll provided with an orbiting wrap formed on a first side surface of the orbiting end plate in the axial direction and engaged with the non-orbiting wrap to form a compression chamber; a plurality of first guides disposed between the frame and the non-orbiting scroll to be located radially outward from the non-orbiting wrap; and a plurality of second guides provided on the orbiting end plate to be located radially outward from the orbiting wrap, respectively, so as to allow an orbiting motion of the orbiting scroll together with the first guides.
