Abstract
An anti-surge valve (11) equipped with a servomotor and connected between the outlet of the compressor (12) and its inlet, the servomotor being controlled from a regulating system (13) which receives at the input a parameter (m) representing the flow of the compressor and a nominal value (c) determined from the inlet pressure and outlet pressure of the latter, for the purpose of injecting some of the outlet flow of the compressor at the inlet of this, in order to keep it above its breakaway point. The device comprises a quick-emptying solenoid valve (16) of the servomotor of the anti-surge valve and means (17, 18) for controlling this as a function of the amount of deviation between the parameter and the nominal value.
