Abstract
A modular sub-assembly of a regulator of a pressure drop detector and intated excess speed governor intended for use with turbo-machines. The pressure drop detector and the excess speed governor are supplied in parallel by a common working fluid at a common pressure PF at low flow and the excess speed governor is capable of reducing the pressure of the working fluid by placing it in communication with a pressure PB which is higher when a predetermined excess speed is achieved, in order to reduce the pressure Pmod at the outlet of the pressure drop detector and to reduce the fuel flow delivered to the injector circuit of the turbo-machine.
