Abstract

L'invention concerne un équipement pour moteur hydraulique à pistons radiaux, comprenant un disque (12) à cames du moteur (10) à pistons radiaux, lequel disque à cames est placé en position fixe, les pistons (15a1, 15a2...) et les galets associés (16a1, 16a2...) ou équivalent étant montés pour se déplacer le long des cames intérieures (12a1, 12a2...) dudit disque à cames, et la partie rotor (14), laquelle fait ofice de cadre de cylindre des pistons, ainsi que l'arbre (18), lequel est relié de façon permanente à ladite partie rotor, étant mis en rotation au moyen des pistons se trouvant dans l'étage de puissance. L'équipement comprend une roue planétaire (28) entraînée par l'arbre (18) ainsi que des roues planétaires (31a1, 31a2...) montées pour être mises en rotation par la roue planétaire (28). L'équipement comprend une roue à couronne (34) entraînée par les roues planétaires (31a1, 31a2...) soit directement soit indirectement, ladite roue à couronne faisant partie du cadre d'enveloppe extérieur (33) de l'équipement, lequel cadre d'enveloppe peut être monté pour tourner.
