Abstract

L'invention propose un moteur hydraulique (10) à pistons (14) radiaux destiné à être entrainé par de l'eau sous pression, qui comporte : - un arbre (12) central qui est pourvu d'une partie excentrique (26), et - des cylindres (20) radiaux qui sont répartis autour de l'arbre (12), dont chaque cylindre (20) reçoit un piston (14) monté mobile en coulissement selon l'axe principal B du cylindre, dans lequel chaque piston (14) comporte une extrémité radiale externe (14B) qui délimite avec le cylindre (20) une chambre pressurisée (24), et une extrémité radiale interne (14A) qui coopère avec la partie excentrique (26) pour entrainer l'arbre (12) en rotation sous l'action du fluide sous pression, caractérisé en ce que le fluide sous pression est de l'eau, et en ce que chacun des composants parmi les cylindres (20), les pistons (14) et l'arbre (12) est réalisé en un acier inoxydable et un composant à faible résistance à la friction est interposé entre deux surfaces en mouvement relatif des cylindres (20), des pistons (14), de l'arbre (12).The invention proposes a hydraulic motor (10) with radial pistons (14) intended to be driven by pressurized water, which comprises: - a central shaft (12) which is provided with an eccentric part (26), and - radial cylinders (20) which are distributed around the shaft (12), each cylinder (20) of which receives a piston (14) mounted so as to slide along the main axis B of the cylinder, in which each piston ( 14) has an outer radial end (14B) which defines with the cylinder (20) a pressurized chamber (24), and an inner radial end (14A) which cooperates with the eccentric part (26) to drive the shaft (12) rotating under the action of the pressurized fluid, characterized in that the pressurized fluid is water, and in that each of the components among the cylinders (20), the pistons (14) and the shaft (12 ) is made of stainless steel and a component with low friction resistance is interposed between two surfaces in relative movement of the cyli ndres (20), pistons (14), shaft (12).
