摘要： A nozzle for use in controlling the flow of liquids incorporating a positive pressure generating device which provides a positive pressure to a diaphragm chamber which serves to retain the valve in an open position after manual opening of the valve by means of a manually operable actuator mechanism. The valve actuator mechanism includes closure means for moving the valve closure means to a closed position and releasable opening means for moving the valve closure means to an open position. A releasable opening means is released when the diaphragm chamber is positively pressurized at a pressure sufficient to retain the valve closure means in a predetermined open position. This provides a nozzle which, after initial manual opening, will be automatically closed when the positive pressure provided by the positive pressure generating device is cut off by the rising level of liquid within the tank. The valve may also be closed at any time by releasing the control handle and permitting it to return to its closed position.

摘要： In a liquid loading system for the gravity loading of a liquid storage tank from a tank truck the present invention provides an improved mechanism for interrupting the flow of liquid when the level of liquid in a tank rises above a predetermined level. The structure includes a valve in the fill line which is moveable between an open position and closed position. A pressure responsive latch means is provided for releasably locking the valve in the open position. A vent passage communicates between the pressure responsive latch means and a predetermined level below the upper end of the underground storage tank. A vacuum passage communicates between the vent passage and a vacuum source in the fill line. The flow of liquid through the liquid fill line generates the vacuum in the fill line in the area of the vacuum passage. Until the level of liquid in the underground tank rises above the end of the vent passage, atmosphere from within the tank is drawn into the vacuum passage from the vent passage. When the level of liquid in the tank rises above the end of the vent passage the vacuum pressure is applied to the pressure responsive latch means to release the valve which moves automatically to the closed position to interrupt the flow of liquid.
摘要翻译：本发明提供一种改进的机构，用于当罐中液体的液面高于预定水平时中断液体的流动。该结构包括在填充线中的阀，其能够在打开位置和关闭位置之间移动。提供压力响应的闩锁装置用于将阀可释放地锁定在打开位置。通气通道在压力响应闩锁装置之间连通并且在地下储罐的上端下方的预定水平面之间连通。真空通道在排气通道和填充管线中的真空源之间连通。液体通过液体填充线的流动在真空通道的区域中的填充线中产生真空。直到地下罐中液体的液位高于排气通道的末端，从罐内吸入的气体从排气通道吸入真空通道。当罐中液体的液面上升到排气通道的末端时，真空压力被施加到压力响应的闩锁装置以释放自动移动到关闭位置的阀，以中断液体的流动。
