Definitions

  • the present invention relates to a hydrostatic vane motor with axial sliding against a continuous surface of stator base with recesses.
  • rotary hydraulic machines comprising sliding but radially sliding vanes, coming to bear, with more or less force, against a peripheral surface with generator parallel to the general axis of rotation.
  • Some of these radial vane machines provide a fluid chamber behind the pallets to exert a thrust on the pallets by means of pistons or not, this thrust can help springs arranged behind the pistons or behind the pallets.
  • the peripheral surface cooperating with the radial paddles is a smoothly curved surface that is smoothly ellipsoid or circular or lobed.
  • the device according to the present invention is of the type of the applicant's generation of devices comprising sliding vanes, but with axial sliding, placed in the housings of the rotor, which vanes are each applied, in a constant and total manner, on a continuous surface.
  • stator bottom which may have rectilinear zones or recesses suitable for the operation of the device, said recesses can also be made mobile.
  • the present invention relates more particularly to a hydrostatic motor with axial sliding vanes in rotor housings and against a continuous surface of stator base with recesses, comprising an intercommunication circuit between pallets, behind these, which circuit allows an integral transmission of pressures between pallets according to their variable location against said stator bottom surface with recesses, which ensures accelerations and decelerations of the axial sliding of the pallets as well as the bonding of said pallets against the stator bottom surface with recesses, the pallets recessed in their acting housings , by pressure build-up in said intercommunication circuit, on pallets projecting outside the housing, each pallet being in contact, in its rotor housing, with a push-button piston for transmitting pressure in said intercommunication circuit between pallets, characterized in that each pallet is equipped with minus a valve opening under the action of a stator magnetic force in the direction: rotor housing base - stator recess and closing under the action of a spring or a portion of the stator base surface to recesses.
  • FIG. 1 In the diagram of FIG. 1, several sliding pallets are represented at different times of their operation, which pallets 1 are each housed in a housing 2 formed in a rotor R opposite a stator bottom S comprising recesses, the one of them E has, relative to an interstitial plane P between rotor and stator and relative to a rotor displacement F, a ramp 3 deviating geometrically from said plane, a range 4 parallel to said plane and a ramp 5 approaching geometrically of said plan.
  • Each pallet 1 is in contact, in its housing, with a push-piston 6 disposed in a channel 6A in communication with an auxiliary circuit 7 made in the rotor. All the channels 6A are in communication with said auxiliary circuit 7 and are all of which in intercommunication.
  • Stator electromagnets can be provided to complete said bonding of the pallets.
  • the auxiliary circuit 7 is supplied with high pressure HP by a valve 8 and, in operation, the pressure prevailing in the auxiliary circuit 7 is a pressure HP 'greater than the pressure HP.
  • HP ' HP + being the thrust force of the re-entrant pallet and S being the active surface of the pressure transmission plunger 6.
  • the application force F2 of the pallet projecting outside the housing is equal to the pressure FI.
  • Phases I and II are propulsion phases with an HP input and a BP output by recess.
  • Phase III corresponds to a freewheeling phase with closed input and output and phase IV represents possible braking or pump operation with low pressure LP and high pressure HP circuits.
  • the pallet is equipped with one or more valves placed in the same direction.
  • a magnetic force FM coming from the stator causes the pallet to stick against the continuous surface of the stator bottom and the opening and closing of the valve designated by the general reference 14, as a function of the position of the pallet relative to the ramps 3 and 5 and at range 4 of the stator recess E:
  • a head 15 of the valve, itself attracted by the magnetic force FM therefore also comes into contact with the ramps 3 and 5 and the range 4.
  • valve During the high pressure active phase, the valve is closed and traps a hydraulic volume (V1) behind the vane which prevents it from coming off. The magnetic force FM, may then not be exerted.
  • V1 hydraulic volume behind the vane
  • the valve head 15 is integral with a rod 16 carrying a disc 17 with openings 18.
  • a spring 19 is interposed between the disc 17 and an annular bottom 20 formed in the pallet.
  • the disc 17 is capable of abutting against an annular shoulder 21 also made in the pallet.
  • hydraulic pressure from the auxiliary circuit 7 causes the pallets to be actuated.
  • the electromagnetic force FM generated simultaneously attracts the vane 1 and its valve 14, keeping them both in contact with the stator track S or ramps 3 and 5 and the intermediate range 4 between a ramp 5 and a ramp 3 .
  • This principle requires the opening of the valve 14 in the rail profiles 3 and 5 of the recesses, allowing the transfer of the volume of fluid V1 corresponding to the movement of the pallet.
  • This device is valid for descending and climbing ramps of recesses.
  • the geometry of the stator track requires the closure of the valve 14, thus canceling any transfer of fluid necessary for the movement of the pallet.
  • the pallet is immobilized during its active phases in the operating position and corresponds to the operation of the recesses in phases I, II and IV of FIG. 2.
  • the pallets may have a curved portion 22 of contact with the stator continuous surface and a compensating portion 23 exposed to the pressure of the fluid so that this pressure is exerted substantially perpendicular to the stator surface, thus improving the application of the pallet against the stator surface.
  • Each pallet can also be provided with an additional surface exposed to pressure and extending laterally at 24 to the pallet and continuing inside the pallet housing. This additional surface makes it possible to avoid any tilting of the pallet and enables the pallet to be sealed against its housing on a contact line 25 situated at the rear edge of the lateral face of the pallet opposite to that exposed at 24 at the preponderant pressure.
