摘要： A three-way normally closed solenoid-operated valve particularly adapted for liquid fuel control. Fuel under pressure is passed from a source to a utilization device when the valve is open and the port connected to the utilization device is drained back (to the fuel tank, for example) when the valve is closed. A tandem valving operation is employed, the solenoid pulling thrust operating to open a third valving orifice to initiate a hydraulic assist feature on valve opening. A positive mechanical connection engages the tandem valving means on a lost motion basis after the third orifice is opened. An arrangement of bleed holes provides for hydraulic balancing and eliminates trapped fuel volumes within the valve which otherwise would impede valve closing.

摘要： A solenoid actuated three-way valve to admit air under pressure to a spring biased piston in a cylinder and, alternatively, to exhaust the cylinder to the atmosphere. Two pilot valves are operated substantially in tandem. The operator has a lost motion connection with the valves for positive valve actuation in the event of pressure failure. A framework between one main valve and one pilot valve for the other main valve causes the one pilot valve to close when the one main valve opens, and vice versa. Both main valves are oriented so that fluid pressure biases them in a closing direction. Small closing bias springs and a small solenoid may thus be utilized. Good valve seating is thus obtainable. The overall size of the valve is also reduced.
摘要翻译：一个电磁致动的三通阀，用于将压力下的空气引入气缸中的弹簧偏压活塞，或者将气缸排放到大气中。两个先导阀基本上串联运行。在压力故障的情况下，操作人员与阀门进行空运动连接，用于正气门执行。一个主阀和另一个主阀的一个先导阀之间的框架使一个主阀在一个主阀打开时关闭，反之亦然。两个主阀都被定向成使得流体压力在闭合方向上偏压它们。因此可以利用小的闭合偏压弹簧和小螺线管。因此可以获得良好的阀座。阀门的总体尺寸也减小了。
