Abstract: A mechanism casing for a hydraulic motor comprises a casing body having a face for application of a lid. The lid is applied tightly on the casing body face and fastened to the casing body by screws via screwheads thereof tightened against an outer face of the lid. The screws pass through the lid via screw passages with circumferential clearance between the screws and screw passages. An O-ring is interposed between the casing body and the lid. At least one of the screw passages are conduit screw passages which open out within a perimeter defined by the O-ring. The conduit screw passages open out into cavities formed in one of either the casing body or the lid, and through which cavities the conduit screw passages permanently communicate with the enclosure defined by the casing. When the screwheads are in an untightened position with respect to the outer face of the lid, fluid communication is effected between said enclosure and the outside of the mechanism casing by way of fluid conduits, which comprise one of the cavities and one of the conduit screw passages.

Abstract: This invention relates to a hydraulic fluid circuit comprising a reversible hydraulic motor, a braking device, two principal conduits respectively connected to the two principal supply and exhaust ports of the motor, a principal selector adapted to occupy a position of rest and two active positions in order to select the circulation of the fluid between the principal ports of the motor and the principal conduits to which they are connected. The circuit also comprises an intermediate system of selection capable of occupying a first configuration in which the principal selector is maintained in its position of rest and a second configuration in which the principal selector is allowed to leave its position of rest. The control means of the intermediate system of selection are connected to the braking device so that this intermediate system can pass from its first to its second configuration only when the brake is de-activated.

Abstract: Pressurized fluid motor comprising a casing, a cylinder block, a cam, an internal fluid distributor and a selector. The bore of the selector has four grooves. Two of them are communication grooves each connected to a main (feed or exhaust) power duct and to a connection duct, the connection ducts being themselves connected to different groups of distribution ducts. The other two grooves of the bore are branch grooves respectively connected to an additional (feed or exhaust) power duct and to a third connection duct. The slide of the selector comprises at least a first selection groove which is adapted to establish communication between the two branch grooves. By modifying only the shape of the slide, and possibly that of the bore of the additional duct, the selector can provide different functions.
