Abstract: 전동식압축기가개시된다. 본발명의실시예에따른전동식압축기는배압실을밀폐하기위한배압씰 부재가내부에공간부를포함하도록구성된다. 상기공간부는, 선회스크롤의선회이동에따라배압씰 부재가탄성변형되어발생되는형상변형분을보상하도록구성된다. 배압씰 부재의상측에는탄성부재가구비될수 있다. 탄성부재는판 스프링등 판형으로구비될수 있다. 이에따라, 탄성부재가배압씰 부재에안정적으로안착될수 있다. 그결과, 선회스크롤이선회운동되어도탄성부재의손상이최소화될수 있다. 배압씰 부재의공간부에는탄성체가삽입될수 있다. 탄성체는배압씰 부재와함께탄성변형될수 있다. 이에따라, 선회스크롤이선회운동되거나축 방향으로이동될경우배압실의밀폐상태및 선회스크롤과고정스크롤의결합상태가안정적으로유지될수 있다.

Abstract: 전동식팽창기및 이를포함하는공기조화시스템이개시된다. 본발명의실시예에따른전동식팽창기는내부에오일분리기를포함한다. 오일분리기는팽창된냉매와혼합된오일을분리하도록구성된다. 오일이분리된냉매는냉매배기구를통해배출되어증발기로유입되도록구성된다. 또한, 냉매로부터분리된오일은오일배출구를통해증발기와전동식압축기를연통하는냉매유로에유입되도록구성된다. 냉매유로에유입되는오일은오일의압력차이에의해이동된다. 따라서, 별도의오일분리장치가전동식팽창기의외부에구비될필요가없으므로, 전동식팽창기및 공기조화시스템의소형화가가능하다. 더나아가, 분리된오일을사이클내에재공급하기위한별도의펌프등이요구되지않으므로, 전력효율이향상될수 있다.

Abstract: 본발명에의한전동식압축기, 고정스크롤과선회스크롤에의해형성되는압축실; 상기선회스크롤의축방향양쪽측면중에서상기압축실이형성되는측면의반대쪽측면에형성되는배압실; 상기압축실과배압실사이를연통하는제1 배압통로; 상기제1 배압통로의양단중에서상기압축실쪽단부에형성되는제2 배압통로; 및상기제1 배압통로와제2 배압통로사이에구비되어상기압축실과배압실사이를개폐하는밸브부재;를포함할수 있다. 이에따라, 리어하우징의축방향길이변화없이인젝션유로를형성할수 있어, 압축기의효율을향상시킴과동시에소형화가가능하다. 또한, 인젝션유로를리어하우징과고정스크롤내에용이하게성형가능하여리어하우징과고정스크롤의제작비용이절감되고생산비가감축된다.

Abstract: The present disclosure relates to a stator of an electric machine, an electromotor having the same, and an electric vehicle having the electromotor. A stator of an electric machine of the power saving interval may include a stator core having a plurality of slots, and a stator winding wound around the slot, wherein the stator winding has a plurality of winding portions connected in parallel with one another for each phase, and each of the winding portions has a segment conductor inserted into three or more slots for each pole. As a result, it may be possible to increase the number of rotations and reduce the external size thereof while maintaining the same output.
