Abstract

A hydraulic motor comprising a rotating cylinder block provided with radial cylinders in which pistons are displaced that rest on a corrugated cam, characterized in that the evacuation conduits of a first group of cylinders open into a first enclosure, the conduits of evacuation of a second group of cylinders opens into a second enclosure, close to and different from the first, and the supply conduits of all the cylinders open into a third enclosure close to and different from the second enclosure, the first enclosure being permanently connected to an evacuation duct and the third enclosure being permanently connected to a supply channel of fluid under pressure, while a mobile distribution slider between the three enclosures, allows to selectively place, in one position, the first enclosure in communication with the second and, in a second position, the second enclosure in communication with the third enclosure.
