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.

Abstract: Disclosed is a pneumatic inflation valve assembly, having: a valve housing defining a valve cavity and including an axial proximate end and an axial distal end, the proximate end including an outlet from the valve cavity and the distal end including an inlet into the valve cavity, the proximate end includes a motion hole, the distal end includes a receiving volume; and a poppet is disposed in the valve cavity that includes an axial proximate stem extending through the motion hole, an axial distal stem is disposed in the receiving volume and is moveable within the valve cavity between an opened position and a closed position, when the poppet is at the opened position the distal stem extends further into the receiving volume than at the closed position, and the center body is axially spaced from the proximate end and the distal end of the valve housing.
