Abstract

Improved oleohydraulic engine, essentially characterized by being constituted from a static axis, whose axis has two axial and equal cams installed on it, facing and positioned in the same way, each comprising three rounded elevations, joined by rounded depressions also, between which cams, is located a cylindrical cage that surrounds the shaft and which is keyed by its periphery to a rotating casing, supported on that axis by means of bearings located outside the cams and adjacent to them, with the peculiarities that the cage cylindrical has nine longitudinal galleries practiced in its constituent wall, equidistant from each other, all parallel to the theoretical axis of the cage and each of them communicated through a hole made in its internal wall with the central passage of the repeated cage and that in each of these galleries is housed a pair of pistons, working in opo and its head is structured to support a ball of support on the tracks of the respective cams, whose pistons are alternately pushed towards the cams by the action of the fluid supplied through a longitudinal shaft gallery, which branches off outlets that emerge at the periphery in the area surrounded by the cage at the height of the inner holes of the galleries of this and fretted among them according to alternate vertices of a regular hexagon, being pushed in the opposite direction by the cams themselves, while the fluid is removed by another organization similar of galleries practiced in the axis, whose three branches emerge according to the other three vertices of the hexagon.
