摘要： A turbo compressor and a refrigeration cycle device having a turbo compressor are provided. The turbo compressor includes a housing having a motor chamber; a drive motor having a stator and a rotor in the motor chamber of the housing; a first compression portion and a second compression portion, respectively, provided on opposite ends of a rotary shaft; a connecting passage that connects an exit of the first compression portion and an entrance of the second compression portion; an inlet passage that penetrates a first side of the housing to communicate with an inside of the motor chamber and guide a refrigeration fluid to the motor chamber; and an outlet passage that penetrates a second side of the housing to communicate with the inside of the motor chamber and guide the refrigeration fluid in the motor chamber out of the housing. Thus, a gas foil bearing provided in the motor chamber may be quickly actuated by supplying the refrigeration fluid to the motor chamber, and at a same time, heat generated from the motor chamber may be quickly dissipated even in a highspeed operation, thereby improving efficiency of the turbo compressor and a refrigeration cycle device having a turbo compressor.

摘要： 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.

摘要： A scroll compressor is provided in which a boss of an orbiting scroll is inserted into and coupled to a boss coupling recess of a crank shaft, so that friction loss of a bearing portion of the crank shaft may be reduced, compression efficiency and reliability of the compressor may be enhanced, and noise and material costs may be reduced. A bush bearing may be formed as a coating on the boss of the orbiting scroll, so that a thickness of the bearing portion of the crank shaft may be reduced. Since an outer circumferential surface of the bearing portion is in contact with an inner circumferential surface of the boss coupling recess, damage to the bearing portion may be prevented.

摘要： 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.
