    • The piston type compressor includes a cylinder block, a rotary shaft, a plurality of pistons, a rotary valve and radial load transmission means. The radial load transmission means transmits a radial load caused by compression reaction force acting on the piston, which is on its compression stroke of the discharge stroke, to the rotary valve, thereby pressing the rotary valve against an inner peripheral surface of the valve chamber. The radial load transmission means has a direction turning portion for turning the radial load toward the inner peripheral surface of the valve chamber between the suction port communicating with the cylinder bore whose piston has completed the discharge stroke and the suction port communicating with the cylinder bore whose piston is on the compression stroke in a rotation direction of the rotary valve from the suction port communicating with the cylinder bore whose piston has completed the discharge stroke.
    • 活塞式压缩机包括气缸体,旋转轴,多个活塞,旋转阀和径向载荷传递装置。 径向载荷传递装置将作用在活塞上的排出冲程的压缩行程的压缩反作用力所产生的径向载荷传递给旋转阀,从而将旋转阀压靠在阀室的内周面上。 径向载荷传递装置具有方向转动部分,用于在与活塞已经完成排放冲程的气缸孔连通的吸入口与与气缸孔连通的吸入口与气缸孔的内周面之间转动径向载荷, 活塞在与活塞已经完成排出冲程的气缸孔连通的吸入口处于旋转阀的旋转方向上处于压缩行程。

    • A terminal for an optical transmission cable, e.g., formed of a central optical fiber surrounded by a heat-deformable plastic coating, comprises a metallic body portion with an axial bore having a relatively small, fiber receiving aperture, an expanding tapered portion, and a cylindrical portion. A heat insulative sleeve is disposed about the bore end at the optical cable receiving face of the terminal.To affix the terminal to a cable end, the terminal body is heated, and the cable axially urged through the bore. The heated terminal body deforms the cable coating, locking the cable into place with the fiber projecting through the relatively small bore aperture, when the assembly cools. The insulative sleeve prevents cable deformation and attendant spurious optical misalignment about the end of the terminal by there separating the cable coating and the heated terminal body.Two terminated optical transmission cable segments may be connected by simply inserting the two terminal body members within an outer sleeve.
