Definitions

  • the present invention relates to a rotary hydraulic device with variable displacement.
  • the device according to the invention is of the type of generation of the Applicant's devices comprising sliding blades, with axial sliding, arranged in alignment in housings of the rotor, which blades are each applied, in a constant and total manner, on a surface.
  • continuous stator background which can be a cycloidal surface, which can be deformed to present rectilinear zones or recesses suitable for the operation of the device.
  • the intermediate space between rotor and stator is of a circularly variable longitudinal axial deviation and defined in part by said continuous surface of stator bottom which is of constant and unique width for a set of pallets considered.
  • the sliding pallets are placed in pairs in rotor housings, on either side of a central stator part, the recesses being opposite back to back of on either side of said central stator part and produced on this part, the pallets approaching one another to be applied to the continuous bottom surfaces, with recesses in this part.
  • a central stator part with bottom surfaces provided on either side of an axis of symmetry, is integral with a fixed shaft portion, the rotor being mounted in shape cage around the stator.
  • the present invention relates to a rotary hydraulic device with variable displacement of the positive displacement pump type with stator and coaxial rotor and with vanes sliding axially in the rotor, the stator comprising at least one bottom surface having, in a variable number, deformations with rectilinear zones. suitable for operation, or recesses, said vanes following said bottom surface, characterized in that said recesses are made on movable elements of the stator, so that the depth of said recesses can be made variable, hence a variable displacement for the device.
  • a command is provided to act, at will, when stopped and / or during operation, on said movable stator elements with recesses and therefore on the depth of said recesses, said movable stator elements being able to move in stator housings.
  • the stator comprises, on the one hand, ramps and, on the other hand, mobile stator elements with recesses, ramps and recesses successively making the relay for constant contact with all or part of the front spout of each sliding pallet.
  • pallets 1 with axial sliding in housings 2 formed in a rotor 3 come to bear, by at least one edge of their projecting beak 4, on a stator bottom surface, with deformations or recesses.
  • This stator continuous surface has the particularity of being composite, in that it includes both a fixed part 5 and moving parts or elements 6.
  • the fixed part 5 has ramps 7 and the mobile elements 6 have recesses 8.
  • the movable elements 6 can move in housings 9 made in the fixed stator part, under the action when stopped and / or during operation, of an external mechanical, hydraulic or magnetic control. Seals 11 are provided between a hub 12 and the control 10 of each movable element 6 and a guide 13 of the corresponding stator housing. Hydraulic balancing channels 14 pass through each movable element 6 right through.
  • each movable member 6 with a recess 8 shows a central plate 15 forming the bottom of the recess and, on either side of this central plate, a wing 16 with raised slope with respect to this central plateau.
  • Each wing 16 is laterally set back relative to the width of the central plate 15 so as to be able to find a place in the stator housing 9 between two fixed stator ramps 7 of the fixed part of the stator 5.
  • a plane area also restricted laterally 17 can make the link between the central plate 15 and each wing 16.
  • the two ramps 7 functionally relay with the more or less landlocked wing 16 so as to ensure constant contact of all or part of the front spout of the pallet 1 considered (or at least of all or part of an edge of this spout) with the stator, when passing the pallet 1, from the stator fixed part 5, the sloping, enclosed wing 6, to reach the restricted portion 17 and the central plate 15. Constant contact is sometimes made with an edge, sometimes with the other edge, with an intermediate flat passage in the case shown in Figures 2 and 3, where each pallet shows, by way of example, a quadrangular front spout and where the stator movable portion 6 has two recesses 8 separated by a flat area 18.
  • low pressure circuits BP, high pressure HP pass through the stator, both in its fixed part 5 by channels 19 and in its mobile portion 6 by channels 20, l action of a pallet 1 on the fluid being indicated by the arrows F1 and the rotor power output by the arrow F2.
  • the vanes are in perfect contact with the stator bottom surface, over their entire length.
  • Appropriate sealing means are provided on the lateral sides of the pallets.
