ABSTRACT:
A conventional mass-spring inertially controlled anti-G suit valve is modified by adding a first electrically actuated solenoid over the mass and valve spindle and a second electrically actuated solenoid over an anti-G suit exhaust port added to the modified anti-G suit valve. The first solenoid can override the inertial valve to begin filling the anti-G suit before acceleration begins. The second solenoid controls a piston to control the exhaust from the anti-G suit to achieve more precise control over the pressure inside the anti-G suit than previously possible. This precise control allows realization of other improvements suggested by the prior art which need precise control of anti-G suit pressures. Pressure transducers can be added to the anti-G suit to provide a feedback signal to a valve controller for the two solenoid valves. The feedback control loop allows the use of less expensive cost, less accurate solenoid valves.
