Abstract: A motor-operated compressor includes a casing having an inner space including a suction space and a discharge space. A first scroll is disposed in the inner space of the casing. A second scroll is configured to orbit in engagement with the first scroll to form a pair of two compression chambers between the first scroll and the second scroll. A rotary shaft is coupled to the second scroll and configured to transfer a rotational force of a driving motor to the second scroll. An intermediate pressure space is formed on one side of the second scroll and in fluid communication with the discharge space. Oil entering the intermediate pressure space from the discharge space forms back pressure supporting the second scroll toward the first scroll, and a portion of the oil flows into the suction space.

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.

Abstract: A motor operated compressor has a housing having a motor chamber and a driving motor located in the motor chamber. The compressor also has a first scroll and a second scroll coupled to the first scroll to form a compression chamber. A rotating shaft is coupled to a rotor of the driving motor and eccentrically coupled to the first scroll. A rear housing of the motor forms a discharge chamber with the second scroll. A shaft receiving portion that radially supports the rotating shaft is located either in the second scroll or in the rear housing. An oil supply guide flow path located either in the second scroll or in the rear housing connects the discharge chamber and the shaft receiving portion. A decompression member inserted into the oil supply guide flow path, reduces a pressure of a fluid passing through the oil supply guide flow path.
