CPC classification number: F04C18/0215 , F04C29/0042
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 motor-operated compressor includes a compression part including a fixed scroll and an orbiting scroll that form a compression chamber configured to compress fluid by an orbiting motion of the orbiting scroll relative to the fixed scroll. A motor part is disposed at one side of the compression part, and configured to generate a drive force to cause the orbiting scroll to make the orbiting motion. A rotary shaft is connected to the motor part and the orbiting scroll to transmit the drive force generated by the motor part to the orbiting scroll. A main frame is disposed between the compression part and the motor part in an axial direction of the rotary shaft, and configured to support the fixed scroll in the axial direction of the rotary shaft. A discharge chamber is formed between the fixed scroll and the main frame, and fluid discharged from the compression part passes through the discharge chamber to outside of the motor-operated compressor.

Abstract: A motor-operated compressor includes a compression unit including a compression chamber formed by a plurality of scrolls engaged with each other. The compressor includes a rotation shaft having one end coupled to one of the scrolls and a rotor coupled with another end of the rotation shaft. The compressor includes a stator radially separated from the rotor by a predetermined gap. The compressor includes a casing having a motor chamber. The stator is inserted in the motor chamber and divides the motor chamber into a first space and a second space. The casing includes an inlet port coupled to the first space to guide a refrigerant toward the motor chamber. The casing also includes a suction guide passage coupled to the second space to guide the refrigerant sucked through the inlet port toward the compression unit. A communication passage portion in the rotation shaft communicates the first and second spaces.

CPC classification number: F04C29/124 , F04C18/0215
Abstract: An electric compressor includes a first scroll, a second scroll engaged with the first scroll and configured to form a compression chamber between portions of the second scroll and the first scroll during orbiting motion of the second scroll relative to the first scroll, and a frame fixed on an opposite side of the second scroll from the first scroll. A back-pressure space is formed between the frame and the second scroll, and pressure in the back-pressure space pushes the second scroll toward the first scroll. A back-pressure passage connects the compression chamber and the back-pressure space, and a valve member is disposed in the back-pressure passage and selectively blocks movement of a fluid from the back-pressure space to the compression chamber.

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.
