Abstract

Machine à pistons radiaux dont la course est commandée par un excentrique. Le piston de positionnement 6 s'applique par ses deux faces de bout sur l'intérieur de l'excentrique 5 modifiant la course des pistons de travail 3. Une couronne 8 fixée sur le piston 6 sépare deux chambres de cylindres 9, 10 alimentés à tour de rôle, mais seulement pendant le déplacement du piston 6, par un fluide amené par des canaux 11, 12, comportant des étranglements 15, 16 et des soupapes de retenue 17, 18 déblocables, d'un passage tournant 23 entre le carter 1 et le bout de l'arbre-manivelle 5 et de conduites de transfert 21, 22 dont l'alimentation est commandée par une soupape 28. Applications aux moteurs ou pompes hydrauliques.Radial piston machine whose stroke is controlled by an eccentric. The positioning piston 6 is applied by its two end faces on the inside of the eccentric 5 modifying the stroke of the working pistons 3. A ring 8 fixed to the piston 6 separates two cylinder chambers 9, 10 supplied with turn, but only during the movement of the piston 6, by a fluid supplied by channels 11, 12, comprising throttles 15, 16 and check valves 17, 18 which can be released, from a rotating passage 23 between the housing 1 and the end of the crank shaft 5 and of transfer pipes 21, 22, the supply of which is controlled by a valve 28. Applications to hydraulic motors or pumps.
