Abstract
A hydraulic motor of variable cubic capacity with retractable partitions sed in radial grooves in a rotor. The partitions are each integral with a guide pin trapped in an endless cam groove of approximately ovoid shape in a surface stator. The partitions also pass through radial grooves in a sleeve housed in a circular groove in the rotor in order to slide therein parallel to the axis of the motor. A reaction member passes through an aperture in the stator in order to remain in frictional contact with an end surface of the sleeve. The driving force comes from oil pressure in a circular groove defined between the end surface of the sleeve and the surface of the stator. The sleeve and reaction member slide jointly.
