Airflow control system

An airflow control system (10;10') for controlling pressure and flow through a flow passage (12;12') with an upstream portion (14;14') and a downstream portion (16;16') includes a valve (11;11') which can open to different positions for controlling pressure at the downstream...

More Information
Summary:An airflow control system (10;10') for controlling pressure and flow through a flow passage (12;12') with an upstream portion (14;14') and a downstream portion (16;16') includes a valve (11;11') which can open to different positions for controlling pressure at the downstream portion (16;16') of the flow passage (12;12'); a valve actuator (18;18') which receives electrical signals to control the opening and closing of the valve (11;11'); and a pneumatic feedback system (20;20') to stabilize the valve actuator (18;18').
