    • A bearing seal includes an outer seal easily displaceable in the radial direction, an inner ring as a ring-shaped rigid portion not extendable in the radial direction, an inner seal having a seal lip, and an outer ring arranged on the outer peripheral portion of the outer seal, in which the spring constant of the inner seal is set to be larger than the spring constant of the outer seal. The sealing performance between the inner seal and the pin is ensured by using the ring-shaped rigid portion as a boundary. When the pin is displaced in the radial direction, the ring-shaped rigid portion is integrally displaced with the pin via the inner seal, and the displacement of the ring-shaped rigid portion can be absorbed by the outer seal.
    • 轴承密封件包括在径向方向上易于移位的外部密封件,作为不能沿径向延伸的环形刚性部分的内圈,具有密封唇缘的内部密封件和布置在 内部密封件的弹簧常数被设定为大于外部密封件的弹簧常数的外部密封件。 通过使用环形刚性部分作为边界来确保内密封件和销之间的密封性能。 当销沿径向位移时,环形刚性部分经由内密封件与销一体地移位,并且环形刚性部分的位移可以被外部密封件吸收。

    • A fuel valve includes a cylindrical flow adjusting member having a cylindrical surface formed with two circumferentially extending V-shaped grooves for liquid fuel and air, respectively. The fuel valve further includes liquid fuel and air supply pipes having O-rings at their respective discharge ports which are kept in abutment with the cylindrical surface such that when the flow rate adjusting member is rotated to a position where the V-shaped grooves extend across and protrude from the respective O-rings, the discharge ports of the supply pipes communicate with the respective V-shaped grooves, so that liquid fuel and air flow. The depths, widths and positions of the respective V-shaped grooves are determined corresponding to an igniting position (preheating step), normal burning positions (high heat to low heat), and a discharge position such that the flow rates of liquid fuel and air can be adjusted in synchronization with each other.
    • 燃料阀包括圆柱形流动调节构件,其具有分别形成有用于液体燃料和空气的两个周向延伸的V形槽的圆柱形表面。 燃料阀还包括液体燃料和空气供应管,它们在它们各自的排放口处具有O形环,它们保持与圆柱形表面邻接,使得当流量调节构件旋转到V形槽延伸穿过的位置时 并且从各O形环突出,供给管的排出口与各V字槽连通,液体燃料和空气流动。 根据点火位置(预热步骤),正常燃烧位置(高热到低热)和排出位置来确定各个V形槽的深度,宽度和位置,使得液体燃料和空气的流量 可以相互同步调整。
