Abstract

This invention relates to a hydraulic motor constituted by a cylinder block mounted to rotate in a support, by two groups of cams integral with said support, by rollers integral in translation with pistons contained in the cylinders of the cylinder block and in abutment on said cams, and by a valve coaxial with the axis of the cylinder block and provided with a slide for selecting the running conditions of the motor, with three positions, each cylinder comprises a pipe connecting it successively to a plurality of orifices disposed in two groups, which each correspond to a group of cams, and the orifices of the same group are regularly distributed on the valve, whilst the orifices of the group of orifices corresponding to the first group of cams comprise first and second orifices, which are alternately placed in communication, the first orifices with a first conduit connected to a source of pressurised fluid, or a discharge tank, the second orifices, which follow the first orifices, with a second conduit connected to the discharge tank or the source of pressurised fluid, respectively, and the orifices of the group of orifices corresponding to the second group of cams comprise third and fourth orifices, which are alternately placed in communication, respectively and selectively, by means of the selection slide, the third orifices with the first conduit, or with the second conduit, or with the fourth orifices, which follow said third orifices, and the fourth orifices with the second conduit, or with the first conduit, or with said third orifices.
