  • Electrically controlled variable pressure pneumatic circuit
    Patent number: 4777383
    Abstract: A pneumatic circuit pressure control device including an electronic comparator for comparing a transducer generated pressure signal from the pneumatic circuit and a desired pressure signal from a desired pressure input generator. The comparison circuit selectively actuates a solenoid-actuated valve which controls the pressure in the pneumatic circuit. Preferably, the solenoid of the solenoid-actuated valve produces an electromagnetic field for electromagnetic induction of a circuit which oscillates the solenoid-actuated valve to produce a variable orifice-like effect when small changes in pressure are demanded by the comparator circuit.
