Abstract
A timed rate control applies to a system having a device 12 for varying a medium 14, a sensor 13 for detecting variation in the medium, and a pneumatic line 11 for varying the device 12 in response to the sensor. This includes many pneumatic control systems that the invention can effectively stabilize to reduce fluctuation and improve operating accuracy and efficiency. The pneumatic line is opened and closed by a solenoid valve 17, and a setable timer 18 variably determines both closed and open intervals for the solenoid valve. The timer is connected to the solenoid valve to control alternate operation between the closed and open intervals while the system operates. This limits each adjustment to a brief duration separated by inactive periods that allow the system to stabilize.
