Abstract
A pneumatic device for continuously varying the pressure of compressed air for feeding pneumatic actuators, comprising a pressure regulation device, which is adapted to receive in input an unregulated pressure line and to provide in output a regulated pressure; an error amplifier, which is adapted to drive an actuation device, which in turn is adapted to actuate the pressure regulation device; and a pressure transducer, which is adapted to detect a pressure value downstream of the pressure regulation device and to feed it back to the error amplifier, for closed-loop control of the pressure regulation device.
