Fluidic valve for warm gas flow control.
Fluidic vortex valve warm gas flow control for rocket application
Research and development of a vortex valve for flow modulation of a 16-percent aluminized 550 deg F solid propellant gas.
Fluidic vortex valve to modulate solid propellant generated hot gas flow
Novel valve for reciprocating compressors - Concept
Thin ring valve for the inlets and exhausts of reciprocating compressors, and possibly for the inlets of internal combustion engines, encircles the cylinder and operates on the Bernoulli principle.
An electrothermally actuated micro valve
Microminiature slide action valve requires power only during actuation and can be used as an on-off or single inlet to alternately selected outlets.
Fast-acting, four-way slide valve
Valve is insensitive to fluctuating sense pressure. It remains in full-open position until the supply pressure is removed.
Bimorph piezoelectric device functions as flapper valve
Flapper valve using a bimorph piezoelectric ceramic bender converts an electrical input into a pneumatic output signal capable of operating fluidic logic elements in a decoder and display system.
Method of stabilizing flueric vortex valves and vortex amplifiers
Inducing losses in the vortex chamber of vortex valves and vortex amplifiers resolves the problem of unstable operation caused by a sufficiently large positive feedback. Induced losses also reduce pressure gain and throttling range of vortex pressure amplifier.
