VOST Flow-Control Valve, Phase I

A cryogenic flow-control valve based on Venturi-Offset Technology (VOST) will be designed and modeled. VOST provides precise linear flow control within a hermetically sealed, thermally efficient, cylindrical envelope. Intended to demonstrate a breakthrough in cryogenic flow control, the valve has no external leak paths, holds position without power and has no dynamic seals. With only two moving parts, the valve is inherently simple and robust.
