摘要： The invention concerns a hydraulic radial piston motor comprising a cam, a distributor and a cylinder block whereof the cylinders are connected to communication orifices located in a communicating surface of the cylinder block. The directional valve has a distribution surface wherein emerge distribution orifices adapted to communicate with the communication orifices during the relative rotation of the cylinder block and of the distributor. The cam has several lobes each including two ramps (50) having each a convex portion (51) and a concave portion (52). The edge of each distribution orifice has a leading portion (B1) through which the communication of said orifice with the communication orifices is opened, and a separating portion (B2) through which said communication is closed. The leading portion and the separating portion (B1, B2) of the edge of at least some distribution orifices (21A, 23A) have each an edge fitting (53A; 53B) comprising at least a recess (54A; 54B), said edge fittings being different depending on whether they are in angular correspondence with the convex zone (51) or the concave zone (52) of the cam ramp.

摘要： The invention concerns a device comprising first and second brake means (16, 20) respectively integral with the first and second element (10, 12) in rotation about an axis of rotation (14), and a brake piston (18) capable of taking up an active braking position to prevent the relative rotation of the two elements and an inoperative position to enable said rotation. Said piston (18) is permanently urged towards its active position by return means (22) and is capable of being displaced towards an inoperative position by fluid supply into a brake release chamber (26). The first and second brake means respectively consist of a first and second series of teeth (16, 20) pertaining to a jaw clutch, the teeth of the first series (16) being integral with the piston (18). The first element (10) and the piston (18) have each a coupling profile (10B, 18B) extending over an axial coupling surface, said coupling profiles forming, viewed in cross-section transverse to the axis of rotation, undulations free from sharp edges, the undulations of the two coupling profiles being capable of fitting into each other to make the piston integral in rotation with the first element.

摘要： The invention relates to a hydraulic motor device with a displacement selector (16) in at least two positions, methods of controlling said selector comprising a hydraulic control chamber (18) that can be supplied with fluid via a control conduit (20) and first opposing return means (17). The device comprises a braking system with a brake release chamber (38) and second opposing return means (39). The control conduit (20) can be connected to the brake release chamber (38) and the first return means (17) can be used to return the displacement selector (16) to its large displacement position when the pressure in the chamber drops below a first threshold value, while the second return means (39) return the braking means (36) to a braking position when the pressure in the brake release chamber drops below a second threshold value, which is lower than the first threshold value.

摘要： The invention concerns a hydraulic engine (1) comprising a housing (2A, 2B), a reaction member with a reaction profile (4), a engine block (6), an internal fluid distributor (16) capable of communicating the engine block (6) cylinders (12) with fluid supply and exhaust conduits, and a braking system comprising first and second brake means (42, 44), respectively integral in rotation with the reaction member (4) and the engine block (6). Said braking system comprises a brake piston (40) capable of being axially displaced to urge the brake means into braking contact or to release the brake. The brake piston is integral with the housing in rotation about the axis of rotation and has a substantially radial braking surface, a first braking member (42) pertaining to the first braking means and being integral with said active surface. The piston has an outer axial surface which co-operates with an inner axial surface, a coupling ring (48) forming part of the housing, the inner and outer surfaces having coupling profiles advantageously formed by undulations.

摘要： The invention concerns a hydraulic radial piston motor comprising a cam, a cylinder block and a distributor. The cylinders of the cylinder block are connected to communication orifices (32A) located in a communication surface of the cylinder block, while the distributor has a distribution surface wherein are provided communication orifices (21A, 23A) adapted to communicate with the communication orifices to drive the motor in rotation. The cam has several lobes (50, 50') each having two ramps (51, 52), each ramp corresponding to a distribution orifice (21A, 23A). The edges of some communication orifices (32A) have each at least a recess (54A, 54B) designed to provide a small communication cross-section with a distribution orifice. The invention is particularly applicable to hydraulic radial piston motors for which the ratio between the number of cylinders and the number of cam lobes is close to 1.
