    Abstract: Fluid flow taking place from a dispenser and is blocked or released by an electromagnet. The release is effective by a start signal such as a dropped coin or a pushed button. The flow of fluid continues for a time determined by a timing circuit. The timing circuit has a counter which counts the number of start signals by causing counting stages to become energized in dependence of the number of start signals received. Energization of the different counting stages causes a variation in the current supplied to a resistance-capacitance timing circuit, thus varying the timing of the timing circuit to allow the same quantity of fluid to flow for each individual portion dispensed, regardless of the static pressure of the fluid remaining in the dispenser.

    Abstract translation: 流体从分配器发生并被电磁铁堵塞或释放。 释放通过启动信号(例如丢弃的硬币或按下的按钮)有效。 流体的流动持续一个由定时电路确定的时间。 定时电路具有计数器,该计数器根据所接收的起始信号的数量,通过使计数级变为通电来对起始信号的数量进行计数。 不同计数级的通电导致提供给电阻 - 电容定时电路的电流变化,从而改变定时电路的定时,以允许相同数量的流体流向分配的每个单独部分,而不管静电压力 液体残留在分配器中。
