    摘要： A drain valve for a fuel filter water separator for an internal combustion engine has a first port mating with the vent opening of the separator, a second port mating with the drain opening of the separator, and a third port. The drain valve is actuatable between a closed position blocking communication of the first port with the third port and blocking communication of the second port with the third port, and an open position providing communication of the first port with the third port and providing communication of the second port with the third port. If the valve is actuated to the open position when the engine is off, collected water and vent air each flow through the third port but in opposite directions. If the drain valve is actuated while the engine is running, pressurized fuel spray from the vent opening and collected water from the drain opening of the separator each flow through the third port in the same direction.

    摘要翻译： 用于内燃机的燃料过滤器水分离器的排水阀具有与分离器的通气口相配合的第一端口，与分离器的排放开口配合的第二端口和第三端口。 排水阀可在第一端口与第三端口的阻塞通信和第二端口与第三端口的阻塞通信的闭合位置之间致动，以及提供第一端口与第三端口的通信并提供通信的打开位置 第二个端口与第三个端口。 如果在发动机关闭时阀被启动到打开位置，则收集的水和排出空气各自流过第三端口但是在相反方向流动。 如果排放阀在发动机运行时被致动，则来自排气口的加压燃料喷雾和来自分离器的排放开口的收集的水分以相同的方向流过第三端口。
