An electromagnetic clutch device for a compressor according to the present invention comprises a crank shaft which includes an inner shaft end, which is housed in a compressor housing, and an outer shaft end which protrudes in an axial direction from the compressor housing. A pulley assembly includes a rotor body and a pulley. The rotor body houses the coil housing therein and is supported by a pulley bearing to rotate on the compressor housing. A coil housing includes a radial inner annular wall, a radial outer annular wall, and a bottom portion at an end in the axial direction of the coil housing near to the inner shaft end. An armature plate is connected with the outer shaft end to be displaced in the axial direction and rotated along with the crank shaft. Outer surfaces of the inner annular wall and the outer annular wall of the coil housing are spaced farther from each other at a portion near to the bottom of the coil housing than at a portion near to an open end in the axial-direction. According to the present invention, the improved shapes of the coil housing and the pulley enable a uniform magnetic saturation to be obtained across arranged bodies while maintaining a space for a coil assembly.

    본 발명의 압축기용 전자기 클러치 장치는 압축기 하우징 내에 수용되는 내부 샤프트 단부 및 압축기 하우징으로부터 축방향으로 돌출하는 외부 샤프트 단부를 갖는 크랭크 샤프트를 포함한다. 풀리 조립체는 회전자 몸체 및 풀리를 구비한다. 회전자 몸체는 코일 하우징을 수용하고 풀리 베어링에 의해 압축기 하우징 상에서 회전 가능하게 지지된다. 코일 하우징은 반경방향 내부 환형 벽, 반경방향 외부 환형 벽, 및 내부 샤프트 단부 부근의 코일 하우징의 축방향 단부의 저부를 포함한다. 전기자 플레이트는 축방향으로 변위 가능한 방식으로 외부 샤프트 단부에 연결되고 크랭크 샤프트와 함께 회전한다. 코일 하우징의 내부 환형 벽 및 외부 환형 벽의 외부 표면은 축방향 개방 단부 부근에서보다 코일 하우징의 저부 부근에서 서로로부터 더 멀리 이격된다.
