Abstract
An inflation valve is provided and includes a valve defining main and command cavities and including first and second valve portions and a valve seat defining an outlet, a poppet disposed in the main cavity and including first and second rods to engage with the first valve portion and to extend through the valve seat and the second valve portion, respectively, and a piston disposed in the command cavity and a solenoid valve. The solenoid valve normally prevents main cavity-command cavity fluid flow to engage the poppet with the valve seat by fluid pressure acting on the poppet in the main cavity and permits the main cavity-command cavity fluid flow when energized to disengage the poppet from the valve seat by balanced fluid pressure acting on the poppet in the main cavity and on the piston in the command cavity to permit main cavity-outlet fluid flow.
