Abstract: A scroll compressor includes a first oil supply passage communicating with a first compression chamber formed between an inner circumferential surface of a fixed wrap and an outer circumferential surface of an orbiting wrap, and a second oil supply passage separated from the first oil supply passage and communicating with a second compression chamber formed between an outer circumferential surface of the fixed wrap and an inner circumferential surface of the orbiting wrap, wherein the first oil supply passage includes an oil supply guide portion provided in a thrust surface of the fixed scroll in contact with the orbiting scroll to define a part of the first oil supply passage, whereby communication between the first and second compression chambers can be prevented, thereby suppressing leakage between the compression chambers, stabilizing behavior of the orbiting scroll, and facilitating formation of the orbiting scroll.

Abstract: A scroll compressor includes a motor portion fixed in an inner space of a casing, a compression portion fixed to the inner space of the casing at one side of the motor portion in an axial direction, a rotation shaft to transmit a driving force from the motor portion to the compression portion, and a flow path guide provided in a discharge space between the motor portion and the compression portion and provided with a guide outlet communicating with the discharge space and opened in a direction toward the rotation shaft. Therefore, most of refrigerant discharged to the discharge space through the flow path guide is moved toward an air gap to enhance an oil separation effect, and thus a normal operation point of the air conditioner can be accelerated.

Abstract: In a rotary compressor, at least any one of a main bearing or a sub-bearing may have at least one axial-direction support portion that extends from an outer circumferential surface of a back pressure pocket and is formed to have a predetermined depth. The compressor may increase an oil film pressure that supports a roller in an axial direction thereof to stably support the roller including a rotational shaft in the axial direction, thereby effectively suppressing or preventing friction loss and abrasion between the roller and the main bearing facing the roller and between the roller and the sub-bearing.

Abstract: A scroll compressor is provided that may include a casing, a main frame, a rotational shaft, an orbiting scroll, a fixed scroll, and an oil supply guide. A second oil supply guide of the oil supply guide may be disposed in at least one of the orbiting scroll or the fixed scroll and extend along a thrust bearing surface between the orbiting scroll and the fixed scroll to provide communication between a first oil supply guide and a compression chamber having a lower pressure than an oil storage space. This may produce a great pressure difference between ends of an oil supply passage including the first oil supply guide and the second oil supply guide, and allow smooth oil supply using differential pressure to the thrust bearing surface between the fixed scroll and the orbiting scroll.
