Title
(EN) PNEUMATIC OPERATING DRIVING DEVICE
(FR) DISPOSITIF D'ENTRAÎNEMENT PNEUMATIQUE
Abstract
(EN)
A pneumatic operating driving device, comprising at least one rotor (1) being connected to a rotatable supported shaft (3) and being brought into rotation by means of air. Near the circumference of said rotor (1), at least one cylinder (5, 15) is positioned, comprising at least one combustion chamber (8) and in which a piston (9, 20) is freely movable, which from a position near said combustion chamber (8) is moved to the other end of said cylinder by means of burning fuel in said combustion chamber, for blowing air out of a nozzle (12) towards said rotor (1). Means, such as a spring (10), are provided to bring said piston (9) back to its original position either said cylinder (15) is executed for double working. A number of cylinders (5, 15) is present divided over the circumference of the rotor (1), in which the point of time of the ignition in the combustion chambers (8) of the cilinders varies.
(FR)
L'invention concerne un dispositif d'entraînement pneumatique, comprenant au moins un rotor (1) connecté à un arbre (3) supporté de manière rotative et entraîné en rotation au moyen d'air. Au moins un cylindre (5, 15) est positionné à proximité de la circonférence du rotor (1), ledit cylindre comprenant au moins une chambre de combustion (8) dans laquelle un piston (9, 20) se déplace librement d'une position proche de la chambre de combustion (8) à l'autre extrémité de cylindre par combustion d'un combustible dans la chambre de combustion afin d'évacuer l'air d'une buse (12) vers le rotor (1). Des moyens, tels qu'un ressort (10), sont prévus pour ramener le piston (9) à sa position initiale, le cylindre (15) et le pistant effectuant un double travail. Un certain nombre de cylindres (5, 15) sont répartis sur la circonférence du rotor (1), le point du moment d'allumage dans les chambres de combustion (8) des cylindres variant.
