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.

Scroll compressor

A scroll compressor includes a casing having an oil storage space, a fixed scroll disposed inside the casing, an orbiting scroll disposed on one side of the fixed scroll and performing an orbiting motion relative to the fixed scroll so as to form a compression chamber, a discharge cover coupled to another side opposite to the one side of the fixed scroll and having a cover bottom surface, and an oil feeder coupled to the cover bottom surface to face a direction opposite to the fixed scroll, to communicate with the oil storage space. The cover bottom surface is disposed at an inner side of an inner circumference of the oil feeder and defines a discharge hole to communicate with the inner side of the oil feeder.

A hermetic compressor according to the present disclosure may include an oil guide disposed on a rotating shaft between a driving motor and a main frame, the oil guide may include an oil block surrounding a main bearing surface between the main frame and the rotating shaft, and one end of the oil block may radially overlap a shaft support protrusion of the main frame. This can suppress oil returned after lubricating a compression unit from being scattered, thereby reducing a leakage of the oil to outside of a casing through a refrigerant discharge pipe.

Computing apparatus and method for initiating automatic booting process when cover is opened

Disclosed are a multimedia device including a flexible display and controlling method thereof. The present invention includes a guide bar, a flexible display configured to be rolled up on an outer circumference of the guide bar, the flexible display having a first region rolled up on the outer circumference of the guide bar and a second region not rolled up on the outer circumference of the guide bar, a receiving unit configured to receive a content and metadata corresponding to the content from a source device, and a control unit adjusting a vertical width of the second region of the flexible display in accordance with a preset condition.

Multimedia device having flexible display and controlling method thereof

A scroll compressor may include a rotational shaft, the rotational shaft including a first frame support having an inner circumferential surface, into which a boss of a first scroll is inserted, and an outer circumferential surface that forms an outer surface of the rotational shaft; and at least one guide hole that extends from the inner circumferential surface to the outer circumferential surface.

Scroll compressor having shaft frame support including guide holes to flow oil for bearing lubrication

A motor-operated compressor includes a housing and a driving motor disposed in an inner space of the housing. The driving motor includes a stator and a rotor. A rotary shaft is coupled to the rotor. A first scroll is provided on one side of the driving motor and the rotary shaft passes through and is rotatably coupled to the first scroll. A second scroll is coupled to the first scroll and an eccentric part of the rotary shaft passing through the first scroll to form a compression chamber between the first scroll and the second scroll. A frame is provided opposite to the driving motor with the first scroll and the second scroll interposed therebetween and configured to axially support the second scroll and radially support one end of the rotary shaft passing through the second scroll.
