Control device for regulating flow of pressurized gas between two pressurized gas devices. |
摘要 |
<p>A pneumatic circuit pressure control device includes an electronic comparator (51,53) for comparing a transducer (19) generated pressure signal (41,49) from a pneumatic circuit (13) and a desired pressure signal (31,39) from a desired pressure input generator (21). The comparison circuit selectively actuates solenoid-actuated valves (15,17) which control the pressure in the pneumatic circuit (13). Preferably, the solenoid (27) of the solenoid-actuated valve (17) produces an electromagnetic field for electromagnetic induction of a circuit (73) which oscillates the solenoid-actuated valve (17) to produce a variable orifice-like effect when small changes in pressure are demanded by the comparator circuit (51,53).</p> |
