    • A protective bumper structure for the exterior surface of tugboats or towboats. The protective bumper includes a backing member for supporting the bumper to the boat, a resilient cushion layer supported on the backing member and a protective face supported on the resilient cushion. The protective face is formed of a durable low friction material and is provided in the form of plural segments, such as spaced elongated strips extending along the length of the resilient cushion. The protective face provides an engagement surface for engaging a cooperating surface on a barge.
    • 拖船或拖船外表面的保护保险杠结构。 保护保险杠包括用于将缓冲器支撑在船上的背衬构件,支撑在背衬构件上的弹性缓冲层和支撑在弹性衬垫上的保护面。 保护面由耐用的低摩擦材料形成,并且设置成多个段的形式,例如沿着弹性垫的长度延伸的间隔开的细长条。 保护面提供用于接合驳船上的配合表面的接合表面。

    • A shut-off member provided on a rear end of an exhaust passage of the personal watercraft is formed to have such a shape that one of the ends of a short pipe made of nitrile rubber is flatly made, thereby including a lip portion having upper and lower side walls which come in contact with each other, and is protruded rearward and downward from a hull of the watercraft. A portion between the upper and lower side walls coming in contact with each other forms a slit to act as an exhaust port. The slit is substantially shut off based on a molding shape thereof if there is no difference between internal and external pressures of the shut-off member, and is opened against the elastic force of a surrounding flexible material depending on a differential pressure and a flow rate of an internal fluid if the internal pressure becomes higher than the external pressure.
    • 设置在个人船舶的排气通道的后端的切断构件形成为使得由丁腈橡胶制成的短管的一个端部被平坦地制成,从而包括具有上部和 下侧壁彼此接触并且从船体的船体向后和向下突出。 在彼此接触的上侧壁和下侧壁之间的部分形成狭缝以用作排气口。 如果切断构件的内部和外部压力之间没有差异,则基于其成型形状基本上切断狭缝,并且根据压差和流量来抵抗周围柔性材料的弹力 如果内部压力变得高于外部压力,则是内部流体。
