Definitions

  • the present invention relates generally to controlled vane pumps and, more particularly, a vane control assembly comprising pushers intended to cause the output of said vane from their housing of the rotor so that they follow the internal curve of the pump body.
  • a vane control assembly comprising pushers intended to cause the output of said vane from their housing of the rotor so that they follow the internal curve of the pump body.
  • Such a type of pump is described in particular in French patents FR-A-2,214,336 and FR-A-2,596,107.
  • the invention also covers a reversible controlled vane pump, provided with the control assembly mentioned above.
  • each pallet of such pumps generally has recesses or channels making it possible to supply the cavity below the pallet, to avoid any problem of cavitation resulting in noises and abnormal wear.
  • These recesses or channels can also be provided in the rotor for the same hydraulic purpose but, in any case, these recesses, whether in the pallet or in the rotor, are provided on the discharge side, which means that the pump is one direction of rotation.
  • the solution may consist in doubling the number of vanes and providing a series of vanes ensuring the operation of the pump in one direction, and another series ensuring operation in the other direction, these two sets of vanes being arranged inversely in the rotor.
  • the problem posed by reversibility becomes the problem of doubling the number of lifters: it is not necessary for the axis of the lifters to move too far away from the axis of the pallet, in order to avoid wear problems abnormal or even jamming.
  • a pallet control assembly is described in particular in US Pat. No. 2,520,087 in which the pushers are slidably inserted in groups of two into cylindrical channels perpendicular to the axis of the pump rotor, forming an angular distance between them.
  • the pushers are cylindrical and have in their middle a flattened part forming a plate of which a planar face of a first pusher is concurrent with the planar face of the second pusher.
  • Such an arrangement does not exclude the presence of pallet springs bearing on a shoulder formed by an edge of said plates and, by having a space requirement due to the size of the plates, it contributes to a weakening of the rotor, in particular for numbers high pallets.
  • the present invention therefore aims to remedy the above drawbacks by means of an arrangement allowing the number of pushers to be doubled without any difficulty and, consequently, to produce a reversible pump without in any way worsening the position of the pushers relative to the axis of the pallets.
  • the pushers are semi-cylindrical in shape and arranged in groups of two so that their axes, each in their plane face, are concurrent, sliding in respective cylindrical channels perpendicular to the axis of rotation of the tree and forming an angular gap between them.
  • a shaft section 1 of a reversible pump rotor comprises at least one group of two pushers 2 and 3 arranged to slide in respective cylindrical channels 4, 5 perpendicular to the axis II of rotation of the shaft 1 and forming between them an angular difference of ⁇ 2 .
  • Each pusher is of semi-cylindrical shape, with a flat face 6, 7 respectively containing the axes AA and BB, also forming the axes of the channels 4, 5.
  • the axes of these these are concurrent and intersect at a point 0 so that the planar faces 6, 7 are in contact with one another while allowing the sliding of the pushers in the channels for the control of the pallets (not shown ) to which they are linked.
  • the axes AA and BB also constitute the thrust lines of the pallets housed in the rotor (not shown), in the axis of the latter. According to this arrangement, the axes AA and BB being concurrent, two pushers can be housed and operate for the same size as a single cylindrical pushbutton of the type generally adopted at present and connected to a set of pallets operating only in only one direction of rotation of the pump.
  • the angular difference between the concurrent axes AA and BB is shown equal to, ⁇ 2 , which may be preferable for reasons of resistance of the shaft 1.
  • the angular difference could be of any other value depending on the number of groups of four pump vanes, for example ⁇ 4 for eight pallets, ⁇ 6 for twelve pallets, the groups of two pushers being close and angularly offset with respect to each other along the axis of the shaft.
