    • A processing torch having a separably assembled torch base and torch head includes a first ring member rotatably provided on an outer periphery of one of the torch base and the torch head, and a second ring member fixed on the other one of the torch base and the torch head. An engaging projection is provided on one of the first and second ring members, and an inclined track provided on the other of the first and second ring members for engaging with the engaging projection. In addition, an elastic biasing member is provided for increasing an engaging force between the inclined track and the engaging projection so as to sealingly engage the inclined track and the engaging projection. Connection and disconnection between the torch base and the torch head are performed by rotation of at least one of the first and second ring members.

    • In a rotary compressor of a vane rotary type, an outer peripheral surface of an eccentric portion of a shaft on a side adjacent to a center of the shaft is located radially inwardly of an outer peripheral surface of a main shaft inserted in a main bearing and that of an auxiliary shaft inserted in an auxiliary bearing. Also, a back clearance means used in mounting a piston on the shaft is provided in each of an inner peripheral surface of the piston and the eccentric portion of the shaft. Such configurations can reduce a diameter of the eccentric portion. A reduction in diameter of the eccentric portion can reduce a viscous force of oil acting between the eccentric portion of the shaft and the inner peripheral surface of the piston to thereby reduce a rotational moment about a center of the eccentric portion of the shaft, which rotational moment acts on the piston in a direction of rotation of the shaft, thus making it possible to reduce a sliding loss that is generated by a reciprocating motion of a vane in a vane groove.
    • 在叶片旋转式的旋转式压缩机中,与轴的中心相邻的一侧的轴的偏心部的外周面位于插入主轴承的主轴的外周面的径向内侧, 辅助轴插入辅助轴承中。 此外,在活塞的内周面和轴的偏心部中的每一个中设置有用于将活塞安装在轴上的后间隙装置。 这种构造可以减小偏心部的直径。 偏心部分的直径的减小可以减小作用在轴的偏心部分和活塞的内周面之间的油的粘性力,从而减小围绕轴的偏心部分的中心的旋转力矩,旋转力 力矩在轴的旋转方向上作用在活塞上,从而可以减少叶片在叶片槽中的往复运动产生的滑动损失。
