Definitions
- the invention relates to vane pumps with a mounted in a pump housing, driven by a shaft rotor, a plurality of outer rotor of this rotor mounted wing plates and a surrounding the rotor and the wing plates outer ring, this either directly in the pump housing, or in a pump housing along predetermined paths movable adjusting ring is arranged.
- Vane pumps with a linearly displaceable adjusting ring to achieve a variable delivery capacity.
- Vane pump with a pivotally mounted about a pin collar described above.
- 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 mounted in bearing grooves (4) of the rotor (3)
- each cell chamber (10) i. in the cylindrical surface of the rotor (3), between the bearing grooves (4) over the entire rotor width, parallel to the bearing grooves (4) of the wing plates (5) arranged by the bearing grooves (4) about a bearing 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 trough (14), seen in the direction of rotation always after the cell chamber center axis (15) is.
- 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.
- transverse grooves (12) according to the invention can also be produced very easily in terms of production engineering.
- Figure 1 the vane pump according to the invention in the side view (without the side cover);
- Figure 2 the representation of the cross-sectional profile 13 of the transverse groove 12 according to the invention, according to Figure 1 (in polar coordinates).
- Rotor 3 radially displaceably mounted wing plates 5 and a 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.
- control lever 20 On one side of the control lever 20 is mounted in the pump housing 1
- Control pressure chamber 23 is arranged.
- a suction kidney 8 and a pressure kidney 9 which is offset by 180 ° relative thereto.
- each cell chamber 10 of the rotor 3 are between the
- Wing plates 5 arranged, spaced from the bearing grooves 4 about a bearing web 11 transverse grooves 12.
- Cell chambers 10 has a trough 14 which is always arranged in the direction of rotation after the cell chamber center axis 15, said Wegstiefddling 14 about 1% to 8% of the outer diameter of the
- transverse grooves 12 of the cell chambers 10 shown in FIG. 1 also always have this invention shown in FIG. 1
- Width of a segment (including the associated
- Cell chamber 10 then over about 63% of the width of the cell chamber 10 along the fictitious "original" rotor outer diameter, a second region in which the cross-sectional profile 13 of the transverse groove 12 to a trough 14, in this embodiment to the radius 31, 5 mm, ie to 1.9 mm (2.85% of the original rotor outside diameter of 66.8 mm) drops.
- This second sector is followed by the lowest point 14, a third sector in which the cross-sectional profile 13 of the transverse groove 12 increases relatively quickly again and already after about 27% of the width of the cell chamber 10 along the fictitious Rotor outer diameter reaches the original outer diameter of the rotor 3 again.
- Embodiment over a range of the cell chamber 10 of about 5% along the original outer diameter of the rotor 3 to the storage groove
- Cross-sectional profile 13 of the transverse groove 12 is surprisingly always guaranteed a low-friction and fluidically optimal complete filling of the pump chambers in vane pumps.
- transverse grooves 12 according to the invention are also easy to manufacture.
- Wing plates 5 is applied, which in turn with their "outside"
- End faces 16 abut the outer ring 6.
- Vane pump are rounded at their ends 16.
- Wing plates 5 arranged radius half the distance between the
- 5 lubrication pockets 18 are arranged in the walls 17 of the bearing grooves 4 of the wing plates arranged in the rotor 3, which clearly minimize the wear between the wing plates 5 and the bearing grooves 4.
- control pressure chamber 23 shown in connection with the solution according to the invention in the figure 1 is on both sides of each of a sealing strip
- sealing strips 24 are slidably mounted in each associated and pressurized by the control pressure of the gallery Hopkinssungshuntnuten 25.
- leaf springs 27 are arranged, which ensure that the sealing strips 24 are still pressed against the pump housing 1 when the vane pump (the motor) is stopped / stopped.
- the guide chamber grooves 25 are via connecting channels
- control pressure chamber 23 connected to the control pressure chamber 23, so that they are safe from the can be acted upon via the inflow opening 22 incoming control pressure of the gallery, and thus ensure a highly reliable and very secure sealing of the control pressure chamber 23 by means of the sealing strips 24 with minimal space under extreme conditions.
