摘要： The invention relates to a regulator, configured to receive a stream of hot air carrying pneumatic power via an air inlet (12), to treat this hot air and to send the treated hot air to an air outlet (14) configured 5 to supply a pneumatic actuator (16), comprising a reference pressure source and an air expansion device comprising a diaphragm (22), the diaphragm (22) being configured to control the flow rate of the hot air stream by comparing the pressure of said hot air stream with the reference pressure of the reference pressure source. The regulator is characterized in that it 10 comprises an air intake (24) configured to receive a cold source, and a pipe (25) for guiding the cold source to the diaphragm (22), so that the cold source forms the reference pressure source and a source for cooling the diaphragm (22).
