摘要： A damper includes a piston that carries a relatively compact control valve for controlling fluid flow through the piston. The control valve provides a variable amount of damping by regulating damper fluid flow between the extension chamber and the compression chamber of the damper during extension and compression strokes. Pressure regulation across the piston is controlled through two alternate flow paths as determined by the control valve. Damping through the first flow path is relatively soft and is determined according to the deflective characteristics of first and second single bi-directional annular disc valves in parallel. Damping through the second flow path is relatively firm and is determined solely by the second bi-directional single annular disc.

摘要： A variable force windshield wiper system for an automobile has a rod which is slidably received within a bore of the drive shaft of the wiper system. The end of the rod contacts a lever arm when the rod extends out from the drive shaft. The lever arm is connected to a spring. The other end of the spring is connected to the windshield wiper arm. As the distance of the rod outside the drive shaft increases, the lever arm rotates about a fulcrum and extends the spring thereby increasing the downward force of the wiper arm toward the windshield. To move the rod, a cam having a threaded exterior surface is mounted on the drive shaft and is attached to the rod. A nut having a threaded interior surface engages the threads of the cam. The nut and cam rotate together if no wiper force change is desired The exterior surface of the nut has ratchet teeth. A pawl is used to selectively engage the ratchet teeth of the nut. When an increase or decrease in force for the wiper arm is desired, the pawl is used to engage the ratchet surface to prevent the nut from rotating. The cam will travel up or down the drive shaft when the nut is prevented from rotating. As the cam moves relative to the drive shaft, the rod moves the lever arm.
摘要翻译： 用于汽车的可变力挡风玻璃刮水器系统具有可滑动地容纳在刮水器系统的驱动轴的孔内的杆。 当杆从驱动轴伸出时，杆的端部接触杠杆臂。 杠杆臂连接到弹簧。 弹簧的另一端连接到挡风玻璃刮水器臂。 当杆在驱动轴外部的距离增加时，杠杆臂围绕支点旋转并延伸弹簧，从而增加了刮水臂向挡风玻璃的向下的力。 为了移动杆，具有螺纹外表面的凸轮安装在驱动轴上并附接到杆上。 具有螺纹内表面的螺母接合凸轮的螺纹。 如果不需要刮水器力，螺母和凸轮一起旋转螺母的外表面具有棘轮齿。 棘爪用于选择性地接合螺母的棘齿。 当需要雨刷臂的力的增加或减小时，棘爪用于啮合棘轮表面以防止螺母旋转。 当螺母被阻止旋转时，凸轮将向上或向下移动驱动轴。 当凸轮相对于驱动轴移动时，杆移动杠杆臂。
