Abstract: A pressure compensating timed fill system with particular application to a clothes washing machine wherein an electrically controlled fill valve is energized for a time period dependent upon the prevailing pressure of the fluid being supplied to the fill valve. The pressure of the incoming fluid is applied to a bellows which positions a sliding contact upon a continuously electrically driven drum, the drum comprising varying areas of conductive metal whereby a circuit including a washing machine timer motor controlling an operational cycle is energized in accordance with the pressure of incoming water to the washing tub.

Abstract translation: 一种压力补偿定时填充系统，特别适用于洗衣机，其中电控制的填充阀根据供给到填充阀的流体的主要压力而被通电一段时间。 输入流体的压力被施加到波纹管，波纹管将滑动接触定位在连续电驱动的滚筒上，滚筒包括导电金属的不同区域，由此，包括控制操作循环的洗衣机定时器马达的回路根据 进入洗涤桶的进水压力。
