Control unit of the force wrapper has an actuating device, in particular to control surfaces of 371

摘要

P the invention relates to the control assemblies of the devices of action. / p & & p & it relates to a unit which comprises two circuits 10, which are separated, one of the two circuits which normally the control of the device 1 of operation, while the other ensures the control with a force sufficient to the extension of the friction forces in the actuating device. In this way, in the event of failure of the first circuit, the second can be very rapidly placed in the circuit, which is much more rapidly than if it does not functioned. Application to the control of the rudders of aircraft. / p
