Abstract

Dispositif de démarrage pour moteur à combustion interne, en particulier pour moteur à piston libre, comportant un réservoir d'air sous pression 11 susceptible d'être mis en communication avec une chambre, en particulier la cham­ brematelas 10, du moteur dont l'équipage mobile 2 a été préalablement amené dans une position convenable. Il comporte deux soupapes 17-21 commandées séquentielle­ ment et disposées sur le conduit de communication 14 entre le réservoir d'air de démarrage 11 et la chambre choisie 10 du moteur, la première de ces soupapes, dite soupape d'ouverture 17, occupant à l'arrêt sa position fermée, sous l'action d'un premier ressort 25, cependant que la seconde soupape, dite soupape de fermeture 21, occupe à l'arrêt sa position ouverte, sous l'action d'un deuxième ressort 26. Starting device for a combustion engine internal, in particular for a free piston engine, comprising a pressurized air tank 11 capable of being placed in communication with a room, especially the room brematelas 10, of the engine whose mobile assembly 2 has been previously brought into a suitable position. he has two valves 17-21 controlled sequentially ment and arranged on the communication conduit 14 between the start-up air tank 11 and the chosen chamber 10 of the engine, the first of these valves, called the valve opening 17, occupying its closed position when stationary, under the action of a first spring 25, however that the second valve, called closing valve 21, occupies at standstill open position, under the action of a second spring 26.
