Abstract: Disclosed is about a motor operated compressor. The motor operated compressor according to an embodiment of the present disclosure is applied with a vapor injection method. In order to implement the vapor injection method, a vapor refrigerant is supplied to the motor operated compressor.
The vapor refrigerant flows along a vapor refrigerant passage formed inside a wall portion of a main housing. The vapor refrigerant passage is in communication with a scroll inner passage formed in a fixed scroll. The scroll inner passage communicates with a compression chamber, so that the vapor refrigerant introduced in is flowed into the compression chamber.
Accordingly, the vapor injection method may be applied without having a separate member to form a passage in an inner space of the main housing. Therefore, a utilization of the inner space of the main housing is improved, and passages of the vapor refrigerant and the refrigerant can be formed in a simple manner.-

Abstract: A motor-operated compressor is provided that may include an orbiting scroll and a rear housing supporting a rear surface of the orbiting scroll. The rear housing may be provided with a discharge space communicating with a discharge port of the orbiting scroll formed at a central portion of a surface facing the orbiting scroll, an oil separation space formed at one side of the discharge space to communicate with the discharge space, and an oil storage space formed at an edge portion of the surface facing the orbiting scroll. An oil return passage may be provided between the oil separation space and the oil storage space, so as to guide oil separated in the oil separation space to the oil storage space. Accordingly, a space for storing oil separated from a discharged refrigerant may be sufficiently secured while allowing the rear housing defining the oil storage space to be easily fabricated.

Abstract: A scroll compressor is disclosed. The scroll compressor may include an oil supply hole (1255) penetrating from an oil passage (1253) to an outer circumferential surface of a rotating shaft (125), and an oil supply groove (1256) communicating with the oil supply hole and formed along the outer circumferential surface of the rotating shaft. The oil supply groove may be provided in plurality axially spaced apart by a preset distance. This can prevent the oil supply groove from invading an oil film section and increase centrifugal force against oil in the oil supply groove, thereby suppressing friction loss and wear between a main frame and the rotating shaft.

Abstract: In a scroll compressor, a discharge chamber is provided in an inner space of a back pressure chamber inner wall, a discharge port is provided inside the discharge chamber, a bypass hole is provided around the discharge port, and a communicating recess portion allowing the discharge chamber to communicate with the bypass hole is provided on an inner circumferential surface of the back pressure chamber inner wall forming the discharge chamber. Through this, the bypass hole may be easily configured in addition to the discharge port, thereby increasing an operation range of the compressor and suppressing overcompression.

Abstract: A scroll compressor according to the present disclosure may include a discharge guide disposed in a high-pressure part to guide refrigerant discharged from a compression part to a refrigerant discharge pipe, and the discharge guide may extend by a preset height from an inner circumferential surface of a casing constituting the high-pressure part toward one side surface of a high and low pressure separation plate. This can guide discharge refrigerant discharged to the high-pressure part to quickly flow to the refrigerant discharge pipe before being spread in an entire space of the high-pressure part, thereby preventing the high and low pressure separation plate from being overheated by discharge refrigerant of high temperature. This can result in preventing suction refrigerant of a low-pressure part from being heated by heat of discharge refrigerant transferred through the high and low pressure separation plate, thereby reducing a specific volume of the suction refrigerant and improving compressor efficiency.
