This device comprises an anti-surge valve (11) fitted with a servo-motor and connected between the output of the compressor (12) and its input. The servo-motor is controlled from a regulation system (13), which receives at its input a parameter (m) representative of the compressor flow-rate and a reference value (c) determined from the input and output pressures of the compressor. This is in order to inject a part of the output flow of the compressor into its input so as to hold it above its stalling point. The device is characterised in that it incorporates a rapid blow-off solenoid valve (16) for the servo-motor of the anti-surge valve and means (17, 18) for controlling the said solenoid valve as a function of the difference between the said parameter and the said reference value. …<IMAGE>… |
