Abstract (en)
The internal combustion engine operating at high speed, giving a high output, has a pair of pistons (1,2) reciprocating inside two sleeves with their piston rods parallel and spaced apart. At the bottom of each piston rod (3,4) is attached a swinging arm (12,13) each turning about an axis formed by spindle (11a, 12a) at right angles to the rods. Each rod carries a disc (6) acting as a valve member which is raised and lowered against the wall (7) of the piston, this acting as a valve seating. The two sleeves act as suction and discharge members for the combustion gases. The two swinging arms control the operation of these values as the pistons reciprocate, and are controlled by a rotating cam (106) between them. The rods carry return springs (15,16). The suction sleeve carries a by pass for the piston to prevent excessive build-up of pressure.

Moteur volumétrique à combustion interne comprenant un couple de pistons (1,2) coulissant le long de chemises correspondantes (1a,2a) en communication respectivement avec le conduit d'aspiration (16) et de décharge (2b) du cylindre du moteur, chaque piston (1,2) étant mobile entre deux positions extrémes, respectivement de fermeture et d'ouverture de la lumière d'afflux (A1) et de défluxion (A2) au ou du dit cylindre. En particulier, le piston (1) relatif au conduit d'aspiration (1b) est muni d'une soupape qui permet l'ouverture du ciel (6) du piston (1) quand ce dernier glisse dans le sens de fermeture de la lumière d'afflux (A1) tandis que le même ciel (6) se maintient en position de fermeture en correspondance à la translation du piston (1) selon le sens opposé.
