Abstract
The control device comprises a moving slide 25 acted on by a return spring 27 and capable of uncovering an orifice 31 allowing hydraulic fluid to be fed to a release chamber 32 moving the control piston 17 removing the "bridging" between the input impeller 2 and the output turbine 10 of the converter 1. The "bridging" is actuated by an electrohydraulic transducer 43 controlled by an electronic device 49 in accordance with the input and output speeds sensed by sensors 46 and 48. "Bridging" of the converter 1 is thus achieved for all the transmission ratios as well as "debridging" on each change from one ratio to another.
