摘要： A control circuit for filling apparatus of the kind wherein there is a nozzle through which liquid is delivered to a container and a filling valve for controlling flow through the nozzle. The circuit includes valve means that supplies sensing pressure to a sensing tube, an exhaust valve through which the pressure in the circuit is adapted to be exhausted to below operating pressure to terminate the filling operation by closing the filling valve in the nozzle and a diaphragm responsive to back pressure developed in the sensing tube to effect operation of the exhaust valve. There is also in the circuit, valve means for at times terminating the flow of sensing air and injecting high-pressure air into the sensing tube to clear it.

摘要： A pressure operable valve in which a valve element is supported by diaphragms for movement relative to valve seats, wherein the diaphragms are designed to bias the valve element to a closed position, a coil spring is disposed with an end engaged with one of the diaphragms to supplement said biasing, and a part supported against the other end of the spring is operable to vary the pressure applied to the valve element by said spring.

摘要： Container-filling apparatus comprising a chamber connected to a source of material and to a filling nozzle and a ram supported for movement in the chamber in one direction to induct material from the source into the chamber and in the other direction to displace material from the chamber through the filling nozzle into a container supported therebelow. Valves control the flow of material from the source to the chamber and from the chamber to the nozzle, a motor effects reciprocation of the ram and a pneumatic control circuit controls the rate of reciprocation of the ram, provides for reducing the rate of the displacement stroke near the end of a filling operation and provides for preventing initiation of the displacement stroke in the event that there is no container in filling position below the filling nozzle. The filling apparatus is designed for single or multiple filling heads and when the apparatus is provided with multiple heads there are feed wheels for moving empty containers one at a time from an input conveyor onto the container supports for filling and for removing filled containers from the container supports after filling onto an output or discharge conveyor. The component parts of the filling head assembly comprising the chamber, ram, valves and filling nozzle are detachably connected by quick-release clamps to enable replacing and/or substituting one chamber and ram for another of different size and/or one nozzle for another in accordance with the viscosity and volume of the material being handled and for ease in cleaning.
摘要翻译：容器填充装置包括连接到材料源和填充喷嘴的室，以及支撑成在一个方向上在腔室中移动的冲头，以将材料从源引入室中并沿另一方向将材料从腔室通过填充喷嘴进入下面的一个容器。阀控制材料从源到腔室和从腔室到喷嘴的流动，电机实现冲头的往复运动，气动控制电路控制冲头的往复运动速率，提供减小排量行程的速率在填充操作结束附近，并且在填充喷嘴下面的填充位置没有容器的情况下，提供防止位移行程的启动。填充装置设计用于单个或多个灌装头，并且当设备设置有多个头时，存在用于将空容器一次一个地从输入输送器移动到容器支架上用于填充和从容器中移出填充的容器的进给轮填充到输出或输出输送机后支撑。包括腔室，压头，阀和填充喷嘴的填充头组件的组成部分通过快速释放夹具可拆卸地连接，以便能够将一个腔室和压头替换和/或替换另一个不同尺寸的喷嘴和/或一个喷嘴用于另一个根据正在处理的材料的粘度和体积以及易于清洁。
