Abstract: A fluid signal inverting unit includes a motion balance unit having a lever which operates a valve. The balance lever is supported at the opposite ends by a pilot signal chamber and a feedback signal chamber and an intermediate pivot support is coupled to position a back pressure leakport valve. Each chamber includes an outer matched linear metal diaphragm fixedly connected to the aligned end of the lever. Increases in pilot pressure result in the outward movement of the linear diaphragm and corresponding outward and pivotal movement of the lever. The lever tends to move away from and open the valve resulting in a decrease in the output pressure and an inverted output pressure signal which may be further amplified and transmitted to a flow booster relay, and as negative feedback signal to the feedback chamber. Decrease in pilot pressure results in an opposite action and an increase output pressure.

Abstract: A control valve includes a single diaphragm as a common wall between an input signal chamber having an input port and an output chamber having a central supply port and an exhaust orifice. The orifice has a seating face parallel to and spaced from the diaphragm. A spring-loaded ball valve unit in the supply passage is aligned with an operator moving with the diaphragm. An increasing input signal first moves the diaphragm to close the exhaust orifice and thereafter moves the operator to open the supply valve. Pressure builds in the output chamber, tending to return the diaphragm and close the supply valve until the output and pilot pressure are balanced. The supply valve then closes. As the exhaust is sealed off, this effectively seals the output chamber. If the signal decreases, the diaphragm uncovers the exhaust orifice until a new balanced state is created. In high flow capacity systems a multiplicity of exhaust orifices are employed to match exhaust and supply flow capacity while maintaining minimal leakage.

Abstract translation: 控制阀包括单个隔膜作为具有输入端口的输入信号室和具有中央供应端口和排气孔的输出室之间的公共壁。 孔口具有与隔膜平行且间隔开的座面。 供给通道中的弹簧加载的球阀单元与操作者与隔膜一起移动。 增加的输入信号首先移动隔膜以关闭排气孔，然后移动操作者打开供给阀。 压力在输出腔中建立，倾向于返回隔膜并关闭供应阀，直到输出和先导压力平衡。 然后供给阀关闭。 当排气被密封时，这有效地密封输出室。 如果信号减小，则隔膜露出排气孔，直到产生新的平衡状态。 在高流量系统中，使用多个排气孔来匹配排气和供应流量，同时保持最小的泄漏。
