It is possible to provide a scroll compressor which can effectively rotate the eccentric side of the swing scroll to the vortex side, while effectively giving back pressure to the vortex side. 스크롤 압축기는 단판 (17) 의 일면측에 소용돌이형상 돌기 (18) 가 설치됨과 동시에 타면측에 편심축과의 걸어맞춤부 (22) 를 구비하고, 또 이 소용돌이형상 돌기 (18) 가 고정 스크롤의 소용돌이형상 돌기와 조합되어 소용돌이형상 압축실을 형성하는 선회 스크롤 (9) 을 구비하고, 선회 스크롤 (9) 의 선회에 따라 작동가스를 압축실내에서 압축하는 것이다. 선회 스크롤 (9) 의 단판 (17) 은 그 축방향을 따라 소용돌이측 부분 (13a) 과 편심측 부분 (13b) 으로 2 분할되고, 소용돌이측 부분 (13b) 및 편심측 부분 (13b) 의 상기 축방향의 상대이동을 허용한 상태에서 편심측 부분 (13b) 의 회전을 소용돌이측 부분 (13a) 에 전동하기 위한 전동수단 (40) (핀 등) 과 소용돌이측 부분 (13a) 에 고정 스크롤측에 대한 배압을 부여하는 탄성부재 (41) 를 구비하고 있다. The scroll compressor is provided with a vortex projection 18 on one side of the end plate 17, and is provided with an engaging portion 22 with an eccentric shaft on the other side, and the vortex projection 18 is formed of a fixed scroll. The swinging scroll 9 is combined with the swirling protrusion to form a swirling compression chamber, and the working gas is compressed in the compression chamber in accordance with the swinging of the swinging scroll 9. The end plate 17 of the revolving scroll 9 is divided into two parts along the axial direction into the vortex side portion 13a and the eccentric side portion 13b, and the axis of the vortex side portion 13b and the eccentric side portion 13b. The transmission means 40 (pins, etc.) and the vortex side portion 13a for rotating the eccentric side portion 13b to the vortex side portion 13a while allowing relative movement in the direction to the fixed scroll side. An elastic member 41 for applying back pressure is provided.

본 발명은 횡형 스크롤 압축기에 관련한 것으로서, 특히 냉매가 원활하게 흐르도록 구조적으로 개선한 고정자에 관한 것이다. TECHNICAL FIELD The present invention relates to a horizontal scroll compressor, and more particularly, to a stator structurally improved to allow a refrigerant to flow smoothly. 이를 위한 본 발명은 일측 끝단부에 평면부를 가진 다수개의 박판을 동심을 이루도록 적층하되, 각 박판의 평면부는 냉매유동방향과 동일방향으로 배열한 것이다. The present invention for this purpose is to stack a plurality of thin plates having a flat portion in one end portion concentric, the flat portion of each thin plate is arranged in the same direction as the refrigerant flow direction.
