Abstract: A motor operated compressor includes a drive motor and a rotary shaft coupled to the rotor. A first scroll disposed on one side of the drive motor is eccentrically coupled to and orbitally moved by the rotary shaft. A second scroll faces the first scroll and is coupled to the first scroll to form a compression chamber. A hollow portion is formed inside the rotary shaft along an axial direction, and an eccentric portion having a rotary shaft side discharge hole extends from the rotary shaft center to a rotary shaft outer circumferential surface. The first scroll includes a rotary shaft coupling portion surrounding an outer circumferential surface of the eccentric portion. The rotary shaft coupling portion is provided with a first scroll side discharge hole formed at a position periodically facing the rotary shaft side discharge hole to discharge compressed fluid to the rotary shaft side discharge hole.

Abstract: A scroll compressor is provided that may include a casing; a discharge cover fixed to an inner space of the casing, that divides the inner space of the case into a suction space and a discharge space; a main frame in the casing, and spaced from the discharge cover; an orbital scroll that performs an orbital motion on the main frame; a non-orbital scroll coupled to the main frame so as to be movable up and down with respect to the orbital scroll, that forms a suction chamber, an intermediate pressure chamber, and a discharge chamber together with the orbital scroll; and a back pressure plate provided between the discharge cover and the non-orbital scroll, that forms a back pressure chamber that communicates with the intermediate pressure chamber. With such a configuration, a bypass valve may be easily installed, and application of an overload minimized.

Abstract: A scroll compressor is disclosed. The scroll compressor may include an anti-rotation mechanism provided with an anti-rotation pin and an anti-rotation ring between an orbiting scroll and a scroll support member facing the orbiting scroll, and an axial thickness of the ring body portion constituting the anti-rotation ring may be larger than an axial depth of a ring insertion groove in which the anti-rotation ring is inserted. This can allow the orbiting scroll and a member facing the same to be spaced physically apart without a separate member, to secure a gap for oil to flow, such that the oil can be smoothly supplied between the orbiting scroll and the member, thereby suppressing seizure or/and friction loss between the orbiting scroll and the member.

Abstract: A scroll compressor is provided, in which a balancing space may be formed on a sub frame to accommodate at least one balance weight, and an oil discharge hole may be formed on a main frame, thereby suppressing, all from being introduced into or remaining in the balancing space to minimize agitation loss due to oil agitation in the balancing space, and forming a thrust surface of the main frame adjacent to an axial center of the drive shaft to suppress axial leakage at a central portion of the orbiting scroll, reducing a size of the main frame to reduce a total weight of the compressor, facilitating a centering operation of the sub frame, and suppressing an outer diameter of the sub frame from being increased, thereby accomplishing miniaturization of the scroll compressor.

Abstract: A scroll compressor is provided. The scroll compressor may include a communication hole formed in a fixed scroll for communicating a discharge space and a thrust bearing surface with each other. This may reduce frictional loss between the fixed scroll and an orbiting scroll. Further, if a high vacuum state is about to occur during operation of the compressor, refrigerant in the discharge space may be introduced into the compression chambers through the communication hole. This may prevent the occurrence of a high vacuum state to thereby prevent damage to the compressor. Additionally, when the compressor is stopped, a pressure equilibrium operation may be performed through the communication hole.

Abstract: A motor-operated compressor includes a housing and a driving motor disposed in an inner space of the housing. The driving motor includes a stator and a rotor. A rotary shaft is coupled to the rotor. A first scroll is provided on one side of the driving motor and the rotary shaft passes through and is rotatably coupled to the first scroll. A second scroll is coupled to the first scroll and an eccentric part of the rotary shaft passing through the first scroll to form a compression chamber between the first scroll and the second scroll. A frame is provided opposite to the driving motor with the first scroll and the second scroll interposed therebetween and configured to axially support the second scroll and radially support one end of the rotary shaft passing through the second scroll.

Abstract: A scroll compressor is provided that may include a casing, an orbiting scroll and a non-orbiting scroll that suctions in a refrigerant from a suction space of the casing, compresses the suctioned refrigerant in a plurality of compression chambers, and discharges the compressed refrigerant into a discharge space of the casing, and a capacity varying device having a first valve and at least one second valve coupled with each other inside of the casing to selectively bypass a portion of the refrigerant in the plurality of compression chambers. With this structure, it is possible to prevent, in advance, refrigerant from being leaked outside of the scroll compressor, reduce pressure loss as a bypass flow path is shortened, reduce a size, weight, and manufacturing costs of the scroll compressor, and vary a capacity of the scroll compressor with a small operating force, and small power consumption.
