摘要： In order to reduce its size of a coil-rotation type electromagnetic clutch in an axial direction and to prolong the life of its brush, a sliding current supply mechanism, which has slip rings and slidable brushes which contact the slip rings, is located inside an inner circumference of a housing boss of a compressor. The current is supplied to an electromagnetic coil via the sliding current supply mechanism. Since the sliding current supply mechanism is located in the boss, a current supply passage is formed without increasing the size of the clutch in axial direction. Thus the installation of the electromagnetic clutch in the engine room is facilitated. Furthermore, since the sliding current supply mechanism is located near the rotational center of the clutch, the life of the brush is prolonged due to the small peripheral velocity of the brush.

摘要翻译： 为了减小线圈旋转型电磁离合器在轴向上的尺寸并延长其电刷的寿命，具有滑环和滑动环接触的滑动电刷的滑动电流供给机构位于 压缩机的壳体凸起的内圆周。 电流通过滑动电流供给机构供给电磁线圈。 由于滑动电流供给机构位于凸台中，因此在不增加离合器的轴向尺寸的情况下形成电流供给通道。 因此，容易将电磁离合器安装在发动机室中。 此外，由于滑动电流供给机构位于离合器的旋转中心附近，所以由于刷子的圆周速度小，刷子的寿命延长。
