  • the pump designers have been and are endeavoring for decades to provide the largest possible inflow cross sections for best possible filling of the displacer cells by means of symmetrically designed "clearances" arranged in the rotor walls of the most varied vane pump designs.
  • the respective pump design then pumps the delivery volume flow by means of these solutions from the suction kidney into the pressure kidney.
  • a major disadvantage of the aforementioned types of vane pumps of the current state of the art is still that at drive speeds in the range of 4500 U / min to over 6000 U / min addition (ie when using these vane pumps, for example, as directly from the crankshaft of a Motor vehicle driven oil pumps) high power losses, a rising noise with increasing speed noise and also increasing with increasing speed wear occurs.
  • the object of the invention is now to develop vane pumps, which avoid the aforementioned disadvantages of the prior art and in addition to the power losses, the noise and wear compared to the prior art pump designs, especially in the speed range from 4,500 U / min to Beyond 6,000 rpm, significantly reduced, but manufacturing technology are easy to manufacture and are also characterized in all speed ranges by a high reliability, a long life, a high specific flow rate and high efficiency.
  • this object is achieved by a vane pump with a rotor (3), which is mounted in a pump housing (1) and driven by a shaft (2), a plurality of wing plates (5) mounted in bearing grooves (4) of the rotor (3) and one rotor ( 3) and the wing plates (5) surrounding the outer ring (6) arranged on a in the pump housing (1) suction kidney (8) and to this offset by 180 ° in the pump housing (1) Druckniere (9), with the radially inner Edge of each cell chamber (10), that in the cylinder surface of the rotor (3), between the bearing grooves (4) over the entire rotor width extending, parallel to the bearing grooves (4) of the wing plates (5) arranged by the bearing grooves (4) a lateral web (11) spaced transverse grooves (12), which according to the invention are characterized in that these transverse grooves (12) have an asymmetrical cross-sectional profile (13), which in each cell chamber (10) via a point (14) with a smallest Radius of the rot
  • asymmetrical design of the cross-sectional profile (13) of the transverse groove (12) in vane pumps were surprisingly the power losses, noise and wear compared to the previously described in the prior art pump designs in the speed range from 4,500 U / min to over 6,000 U / min addition significantly reduced.
  • the solution according to the invention is easy to manufacture in terms of production and is characterized in all speed ranges by a high reliability, a long service life, a high specific volume flow and also a high degree of efficiency.
  • FIG. 1 the vane pump according to the invention in the side view, without cover with a mounted in a pump housing 1, by a shaft 2, in this embodiment of the crankshaft directly driven rotor 3, with a plurality of bearing grooves 4 of the rotor 3 radially displaceably mounted wing plates 5 and a the Rotor 3 and the wing plates 5 surrounding outer ring 6 shown.
  • This outer ring 6 is arranged in this embodiment in a rotatably mounted, provided with a control lever 20 lock slider 7.
  • On one side of the control lever 20 is mounted in the pump housing 1 compression spring 21 at.
  • each cell chamber 10 of the rotor 3 there is furthermore a suction kidney 8 and a pressure kidney 9 which is offset by 180 ° relative thereto.
  • a suction kidney 8 and a pressure kidney 9 which is offset by 180 ° relative thereto.
  • At the radially inner edge of each cell chamber 10 of the rotor 3 are between the bearing grooves 4 of the wing plates 5, over the entire width, ie along the lateral surface of the rotor 3 extending, parallel to the bearing grooves 4 of the wing plates 5 arranged by the bearing grooves 4 to a bearing web 11 spaced transverse grooves 12 are arranged.
  • these transverse grooves 12 as already explained, an asymmetrical cross-sectional profile 13 which has a point 14 in each of the cell chambers 10 with a smallest radius of the rotor is always arranged in the direction of rotation of the cell chamber center axis 15, said point 14 in Embodiment about 1% to 8% of the outer diameter of the rotor 3 radially within this imaginary, the bearing webs 11 fictitious interconnecting outer diameter of the rotor 3 is located. It is also characteristic that the asymmetrical cross-sectional profile 13 of the transverse grooves 12 on the rotor 3, as shown in this embodiment, can also be described by a polynomial of the 4th degree.
  • the illustrated 7-blade vane pump is the width of one segment (including the associated wing panel sections) 51.4285 °.
  • the rotor shell in a cell chamber 10 it follows immediately next to the cell chamber 10 on both sides limiting bearing grooves 4, ie in the region of the bearing webs 11 (in this embodiment, on both sides over a "width range" of the cell chamber 10 of about 5%) the " original "rotor outside diameter.
  • the thus formed, immediately adjacent to the bearing grooves 4 of the wing plates 5 arranged bearing webs 11 ensure the required power transmission and rigidity of the rotor 3 even at high stress of the vane pump.

  • a guide ring 19 is fitted in the rotor 3 which rests against the "inner" end faces 16 of the wing plates 5, which in turn rest with their "outer” end faces 16 on the outer ring 6. It is characteristic that the wing plates 5 of the vane pump according to the invention are rounded at their end faces 16.
  • the radius arranged on the end faces 16 of the wing panels 5 corresponds to half the distance between the end faces 16 of the wing panels 5.
  • control pressure chamber 23 is sealed on both sides in each case by a sealing strip 24, wherein the sealing strips 24 are displaceably mounted in respectively associated and pressurized by the control pressure of the gallery Actuallysungshuntnuten 25. It is advantageous in this context that in the istsungshuntnuten 25 (below the sealing strips 24) resilient elements, eg as in the FIG.
