    • PROBLEM TO BE SOLVED: To provide a vibration type compressor capable of reducing contact between a piston and a cylinder by a simple structure without providing a mechanical supporting part.
      SOLUTION: A moving member of a liner motor is provided with supporting coils 107 wound independently for each outer yoke 104 for controlling the position of the piston 102 in the radial direction, the piston 102 is constituted of an inner yoke 102a, a main magnet 102b, and a side magnet 102c, and current flowing to the supporting coil 107 is controlled. Thereby, suction force acting on the inner yoke 102a is adjusted, and the piston 102 and the cylinder 103 are maintained in a non-contact state while securing a gap between the piston 102 and the cylinder 103.

    • 要解决的问题:提供一种能够通过简单的结构减少活塞和气缸之间的接触而不设置机械支撑部的振动式压缩机。 解决方案:衬套电动机的移动部件设置有用于每个外磁轭104独立地缠绕的支撑线圈107,用于控制活塞102在径向的位置,活塞102由内磁轭102a, 主磁铁102b和侧磁体102c,流过支撑线圈107的电流被控制。 因此,调整作用在内轭架102a上的吸力,同时确保活塞102和气缸103之间的间隙,使活塞102和气缸103保持在非接触状态。(C) 2008年,日本特许厅和INPIT
