Definitions

  • the invention relates to a positive displacement pump with a Wing for mutual separation of the two chambers in the Housing space of the pump housing, with the characteristics of Preamble of claim 1.
  • a vane pump which has a divided wing, wherein the one another facing ends of the wing parts teeth and tooth gaps have over which they interlock.
  • the two wing parts at their facing each other ends not sufficient against the Wing tips attacking tangential forces supported.
  • a positive displacement pump in the wing consists of two wing sections, whose are formed stepped facing each other and the individual steps nut and spring into each other to grab. Although such a wing can be in its length be changed, but the individual are based Wing sections only slightly off each other.
  • the object underlying the invention is now It is to specify a positive displacement pump in which the Wing parts against forces acting on the wing tips are better supported.
  • the two Wing sections at their facing each other Side surfaces on each other and are thereby against Tilting secured.
  • a guide of the two Wing sections is created by the two mutually facing side surfaces grooves and springs have, in the longitudinal direction of the wing itself extend, i. the orthogonal to the drive shaft run.
  • the two wing sections can so only slide in the longitudinal direction and become about the grooves and springs prevented in the direction of Drive shaft to shift.
  • the Wing sections are formed symmetrically, a Have flat profile and / or that the wing sections are identical.
  • These Ausgestalltungen have the significant advantage that the wing sections relative simple and therefore inexpensive to produce and that, in particular by the identical embodiment of Wing sections, storage is simplified.
  • wing sections both in Direction of the height of the wing, the length of the wing and the thickness of the wing is achieved by the wing in its height, in its length and / or in its thickness partially deposed.
  • Each wing section has at least in sections, the entire height, length and / or thickness of the wing.
  • the grooves and springs are designed so that they have a Make labyrinth seal.
  • the free space between the grooves and springs are sized so that Temperature variations of the wing do not cause jamming or lead to loss of leadership.
  • the grooves have a depth ranging from 20% to 50%, especially 25% to 33%, the thickness of the wing corresponds.
  • a Groove depth of 25% of the thickness of the wing becomes the advantage scored that the entire wing is essentially the same Has wall thicknesses, so that in injection-molded wings no cavities need to be provided so that the Stability of the wing is not affected.
  • Wing sections have uniform wall thicknesses. This creates the possibility that the Wing sections easily by injection molding can be produced. In die casting manufactured wing sections are also conceivable.
  • FIG. 1 shows a perspective view of a Total designated 10 positive displacement pump, which a Pump housing 12 and a cylinder head 14 includes, in which a drive shaft 16 is mounted.
  • a rotor 18 is mounted, the one for Axle of the drive shaft 16 parallel recess 20, which in the illustrated embodiment by the rotor center extends, wherein in the recess 20 a slidably mounted in total with 22 designated wings is.
  • the wing 22 projects with its two ends 24 and 26th out of the recess 20 of the rotor 18 and lies by means of sealing strips 28 on the inner peripheral wall 30 of the Rotor 18 on.
  • the sealing strips 28 are pivotally connected to the Ends 24 and 26 attached so that these over two Line contacts on the inner peripheral wall 30 permanent issue. In simple embodiments, too the ends 24 and 26 directly on the inner peripheral wall 30 of the Rotor 18 abut.
  • the wing 22 is in perspective Representation reproduced and it is clearly visible that this apart from the two sealing strips 28 off two wing sections 32 and 34 consists.
  • the two Wing sections 32 and 34 are identical and lie with their side surfaces 36 to each other. These Side surfaces 36 are provided with grooves 38 and springs 40, in alternating sequence in the direction of the longitudinal axis of the wing 22, i. orthogonal to the axis of Drive shaft 16 are aligned.
  • the cross section of the Grooves 38 and springs 40 is substantially rectangular in shape, as is apparent from the cross section V-V in Figure 5.
  • FIG. 3 a section III-III through the middle of Wing 22 is shown in the longitudinal direction, shows the engagement the spring 40 of the wing portion 34 in the grooves 38 of the Wing section 32 and in particular over a wide Area extending overlap, resulting in one optimal guidance, on the other hand a very good seal causes.
  • the springs 40 are not only with their Side surfaces on the side walls of the grooves 38, but also base their base on the bottom of groove 38.
  • Such a wing 22 designed by more than 50% its length can be extended, and still offers one optimal rigidity and guidance and does not tilts within the recess 20 of the rotor 18th
  • FIG. 5 clearly shows how the Wing section 34 on the top shown there the Wing section 32 completely overlaps and thereby also a support on the opposite side of the recess 20th experiences.
  • the grooves 38 and springs 40 extend over about 20% of the total thickness of the wing 22, thereby as far as possible the uniform thicknesses at the Wing sections 32 and 34 are created.
