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).

摘要： The invention relates to a regulator, configured to receive a hot air flow via an air inlet (12), to treat this hot air and to transmit the treated hot air to an air outlet (14) configured to supply a pneumatic actuator (16), comprising at least one temperature-sensitive electrical and/or mechanical element (36, 37), and a regulator body (100). The regulator is characterized in that the regulator body is composed of a heat-conducting hollow enclosure (28) at least partially surrounding a duct (22) for transporting the hot air flow, said cavity being at least partially filled with a metal mesh produced by additive manufacturing that allows the cooling air to circulate, and in that the temperature-sensitive electrical and/or mechanical element (36, 37) is arranged in, or in contact with, the regulator so as to be cooled by the cooling air by thermal conduction.
