    • A pressurized fluid supply hose which conducts pressurized fluid discharged from a pump to a fluidically operated device is disclosed. A spiral tube formed by two spirally wound band members is fixed by caulking in one end of a steel pipe. The outer shape of the one end of the steel pipe includes a taper portion formed to slope gradually between a thin portion and an outer diameter portion. By effecting a caulking process with a caulking tool having a pressing portion extending in parallel to an outer surface of the steel pipe, the outer taper portion of the steel pipe is contracted to formed an inner taper portion at an internal surface thereof, and one end of the spiral tube is fixed to the inner taper portion. Because the spiral tube is gradually deformed along the inner taper portion of the steel pipe, it can avoided that a large clearance is formed between the two band members of the spiral tube.
    • 公开了将从泵排出的加压流体传导到流体操作装置的加压流体供应软管。 由两个螺旋缠绕带部件形成的螺旋管通过在钢管的一端中的铆接而固定。 钢管的一端的外形包括形成为在薄部分和外径部分之间逐渐倾斜的锥形部分。 通过利用具有与钢管的外表面平行延伸的按压部的铆接工具进行铆接处理,钢管的外锥形部收缩,在其内表面形成内锥形部, 的螺旋管固定在内锥形部分上。 因为螺旋管沿着钢管的内锥部逐渐变形,所以能够避免在螺旋管的两个带状部件之间产生大的间隙。

    • A power steering system which includes a fluid source that supplies pressure fluid of a constant flow rate, a fluid motor for supplementing manual steering torque, a servo-valve for distributing fluid to the fluid motor, and a reaction device for applying hydraulic reaction or feeling to a steering wheel. A magnetic pressure control valve is connected to the reaction device to control fluid pressure applied thereto in accordance with a vehicle operating condition, such a vehicle speed. A flow dividing valve serves to divide the pressure fluid of a constant flow rate in a predetermined ratio into first and second flows which are respectively directed to the servo-valve and reaction device. The predetermined ratio is varied such that the flow rate of the fluid supplied to the reaction device increases as the pressure of the fluid supplied to the fluid motor increases.
    • 一种动力转向系统,包括供给恒定流量的压力流体的流体源,用于补充手动转向扭矩的流体马达,用于向流体马达分配流体的伺服阀,以及用于施加液压反应或感觉的反作用装置 到方向盘。 磁性压力控制阀连接到反应装置,以根据车辆操作条件(如这种车速)来控制施加到其上的流体压力。 分流阀用于将预定比例的恒定流量的压力流体分成分别指向伺服阀和反应装置的第一和第二流。 改变预定比例,使得供应到反应装置的流体的流量随着供应到流体马达的流体的压力增加而增加。
