    • A filling valve for hydrodynamic transmission elements, e.g. a hydrodynamic coupling or a hydrodynamic converter, which partially controls a speed dependent volume stream in conformity with the speed of rotation. A hollow spring-loaded control piston which is axially displaceable in a control bushing has one of its end faces actuated by the volume stream of a filling pump against the thrust of the spring acting thereupon while the outside of the other end face of the hollow piston communicates through a throttle bore with the interior of the hollow piston. The interior of the hollow piston is adapted through control slots in the circumferential surface of the piston to respectively communicate with a feeding line leading to the transmission elements and with a return line. Temperature responsive means are provided adjacent to and for cooperation with said throttle bore for increasing the free crossection of the throttle bore in response to a decreasing temperature and for decreasing the free crossection of the throttle bore in response to an increasing temperature.
    • 用于流体动力传递元件的填充阀,例如 流体力学耦合或流体动力转换器,其部分地控制与转速相符的速度相关的体积流。 在控制衬套中可轴向移动的中空弹簧加载控制活塞,其一端的表面由填充泵的体积流驱动,抵抗作用在其上的弹簧的推力,而中空活塞的另一端面的外侧 通过节流孔与中空活塞的内部连通。 中空活塞的内部通过活塞的圆周表面中的控制槽适应分别与通向传动元件的馈送线和返回线路连通。 温度响应装置被设置成与所述节流孔相邻并用于与所述节流孔配合,以响应于降低的温度增加节流孔的自由横截面,并且响应于升高的温度减小节流孔的自由横截面。
