Abstract: System for driving at least one compressor that includes an input able to be connected to a belt secured to a rotary machine, an output able to be connected to the compressor, an epicyclic gear train the annulus gear of which forms a flywheel and the sun gear of which is connected to the output of the system, and a device allowing the configuration of the epicyclic gear train to be modified so that this gear train selectively adopts at least the following configurations: (i) a configuration in which the epicyclic gear train is coupled to the input of the system, (ii) a configuration in which the epicyclic gear train has no internal degree of freedom and in which the epicyclic gear train is uncoupled from the input of the system.

Abstract: The invention relates to a device for transmitting mechanical torque between a driving member and a driven member, in particular between a heat engine and an air compressor (2) for supplying power to the engine. Said transmission device includes at least one pulley (10, 11, 12, 13), for transmitting the torque between the driving member and the driven member, and a release means (17) controlling at least one of said pulleys (10, 11, 12, 13) so as to enable the transmission of the torque between the driving member and the driven member when the latter are in an engaged state, or so as to restrict the transmission when the latter are in a disengaged state.

Abstract: The invention relates to a device for heating the heat engine (7) of a vehicle, comprising: a reactor (3) in which a reagent that can cause an exothermic reaction with a reaction fluid is disposed, a circuit (5) for supplying reaction fluid to the reactor (3), a heat-exchange circuit (8) between the reactor (3) and the heat engine (7) of the vehicle, and a circuit (9) for regenerating the reagent.
