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 scroll compressor is disclosed. The scroll compressor includes a first scroll and a second scroll engaged with the first scroll and configured to perform an orbiting movement. The second scroll forms a compression chamber between the first scroll and the second scroll. The scroll compressor includes a frame positioned opposite the first scroll with the second scroll interposed therebetween. The scroll compressor also includes an oldham ring that has an annular ring portion and a key portion protruding from the ring portion. The key portion is slidably coupled to a key groove provided in the frame or in the second scroll to allow the second scroll to perform an orbiting movement with respect to the first scroll. The scroll compressor also include a reinforcing member coupled to the key portion. The reinforcing member is positioned between the key groove and the key portion.

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.
