A vehicle, such as a missile, with a pilot valve system controls the vehicle's thrust valves despite a hostile propellant gas environment. The pilot valve system can have one or more pilot valves. Using refractory elements, the pilot valve ball reciprocates between a supply seat and a vent seat which is subject to the filtered inflow of propellant thrust gases. When open, the pilot valve allows the stray thrust gas to communicate to a control chamber which closes a poppet against a valve seat in the nozzle. When an associated solenoid closes the pilot va...
1. A pilot valve for redirecting thrust to control a thrust valve, comprising:a housing having a supply valve seat and a vent valve seat defining an internal valve chamber; the supply valve seat defining a thrust inlet opening; the vent valve seat defining a pressure vent opening; the valve chamber in communication with the thrust inlet opening, the pressure vent opening, and configured to communicate with the thrust valve; a valve gate moveable between the supply valve and vent valve seats to selectably seal either the supply valve seat or the vent valv...
