An electric compressor includes a casing; a compression mechanism for compressing a refrigerant inside the casing; a motor for providing power to the compression mechanism; and an inverter for controlling the motor, and the casing includes an inverter cover for sealing the inverter from an outside, the inverter cover includes a plate-shaped plate, and the plate includes a first plate portion and a second plate portion extending from the first plate portion and protruding toward an inside in which the inverter is embedded. Accordingly, it is possible to achieve increased rigidity of the inverter cover, reduced vibration and noise, and suppressed weight increase at the same time.

Electric compressor

A scroll compressor including a first bearing rotatably supporting a rotary shaft relative to a casing at one side of the rotary shaft with respect to a motor, a second bearing rotatably supporting the rotary shaft relative to the casing at the other side of the rotary shaft with respect to the motor, and a third bearing rotatably supporting the rotary shaft relative to an orbiting scroll at the opposite side of the first bearing with respect to the second bearing. The distance between a first bearing center and a third bearing center is a predetermined distance, the distance between a motor center and the third bearing center is longer than the distance between the motor center and the first bearing center, and the distance between a second bearing center and the motor center is longer than the distance between the second bearing center and the third bearing center.

Multi-bearing scroll compressor to enhance load management

Provided is a scroll compressor which has a reduced noise vibration by minimizing an impact sound generated when the operation of the scroll compressor is stopped.

Scroll compressor

The present disclosure relates to a scroll compressor, and it is possible to constitute a depressurized resistance value of a first orifice disposed on an oil recovery part to be lower than a depressurized resistance value of a second orifice, thereby maintaining/enhancing volume efficiency upon driving under a high pressure condition where a pressure of discharged refrigerant is high by increasing the back pressure of a back pressure chamber.

Scroll compressor includes a shaft rotatably supported to a casing; an eccentric bush having a recess part into which one end portion of the shaft is inserted, an eccentric part eccentric to the shaft, and a balance weight disposed at the opposite side of the eccentric part with respect to the recess part; an orbiting scroll for performing the orbiting motion in interlock with the eccentric part; and a fixed scroll for forming a compression chamber together with the orbiting scroll. The casing has an orbiting groove in which the eccentric bush performs the orbiting motion, a buffer member is interposed between the orbiting groove and the balance weight. Rotation clearance is formed between the recess part and the shaft. The buffer member is compressed between the balance weight and the orbiting groove before the recess part and the shaft contact each other by the rotation clearance.

Scroll compressor with buffer member between the orbiting groove and the balance weight

A scroll compressor includes a shaft being rotated by a drive source, an eccentric bush including a recess part into which the shaft is inserted and an eccentric part being eccentric to the shaft, an orbiting scroll configured to perform an orbiting motion in interlock with the eccentric part, a fixed scroll tooth-engaged with the orbiting scroll, and a buffer member configured to prevent an outer periphery of the shaft and an inner periphery of the recess part from coming in contact with each other, wherein the buffer member is formed to be able to perform a relative motion with respect to the shaft and the recess part. Accordingly, the scrolls are prevented from being damaged, an impact sound is prevented from being generated, and an increase of an inertial force and an unbalance force of a rotating body is suppressed.

Scroll compressor including a buffer member between a shaft and a recess part of an eccentric bush

A scroll compressor that includes a rotating shaft, an eccentric bush having a recess, into which one end of the shaft is inserted, and an eccentric portion eccentric to the shaft, an orbiting scroll operatively connected to the eccentric portion for orbiting, a fixed scroll engaged with the orbiting scroll, and a buffer member interposed between the one end of the shaft and the recess. Therefore, it is possible to prevent damage to the scrolls due to liquid refrigerant compression during initial operation and to prevent an impact sound between the shaft and the eccentric bush due to the rotational clearance therebetween.

Disclosed herein is a compressor that includes a casing, a fastening part disposed at a portion corresponding to a support bracket provided in a compressor mounting part of a vehicle on the casing, and a fastener connecting the support bracket to the fastening part, wherein a compressor's center of gravity and a compressor's point of support supported by the fastener are positioned in a longitudinal direction of the fastener. The present disclosure has an effect of relieving rotational moment and fatigue stress occurring in the compressor when the compressor is mounted to the vehicle.

Compressor for vehicle

The present invention relates to an electric compressor. The electric compressor according to an exemplary embodiment of the present invention includes a rear housing in which a discharging chamber to which a coolant is discharged is formed; an oil separator disposed in the discharging chamber, having a coolant introduction hole through which the coolant is introduced formed therein and disposed to be eccentric to one side of the rear housing; a partitioning wall partitioning an inner region of the discharging chamber into different regions and having communication portions formed at different positions; and a resonance chamber in which introduction and diffusion of the coolant passing through the communication portions are simultaneously performed.

Disclosed herein is a compressor with an oil return unit. The compressor includes: a main housing; a turning scroll which is turnably mounted to the housing; a fixed scroll which engages with the turning scroll and forms a compression chamber; an auxiliary housing which includes a discharge space communicating with an outlet side of the fixed scroll, and a collection space in which oil collected in the discharge space is temporarily stored; an oil return passage which is formed in the fixed scroll and communicates with the collection space; and an oil supply passage which is formed in the main housing, communicates with the oil return passage, and diverges such that oil is supplied to at least two places.
