<p>The invention relates to an engine with radial pistons 9, which are coupled to elastic return means 25 for free-wheeling operation. Said elastic means are constituted by springs 25 whose number is equal to that of the pistons and by levers 21 mounted to pivot, each with respect to a piston 9, about an axis parallel to the axis of rotation 6 of the cylinder block 7, and equal in number to the springs, whereas each spring 25 is coupled to two levers 21, each lever constituting the bond for two springs 25. An application is the production of a hydraulic engine which is reliable and of simple design.</p> |
