Definitions

  • the invention relates to a vane pump or a Vane motor with the features of the generic term Claims 1, 2 or 3.
  • a vane pump is known from DE 37 39 078, at which, corresponding to that in the preamble of claims 1 and 2 explained pump construction, the radial in the pump rotor slidably guided, plate-like rotor blades through in the end of the rotor chamber and coaxial to it, annular guideways held in their conveying position become.
  • the guideways are through an annular surface of annular grooves formed, in which the rotor blades with peg-like Projections, each of one of the wing tips protrude, intervene with radial play.
  • annular Guideways an advantageous adjustment of the outer Longitudinal edge of the rotor blades to the peripheral wall of the rotor chamber allow to promote a gaseous or liquid Fluid already at the beginning of the rotor rotation guarantee, this solution can not optimally satisfy.
  • the invention is therefore based on the object Vane pumps or vane motors in the preamble to improve the construction explained in claims 1 and 2, that the assignment of the Longitudinal edge of the rotor blades to the peripheral wall of the rotor chamber remains constant.
  • this result is achieved by achieved a special training of the guideways that a perpendicular to the axial plane defined above correspondingly slightly larger diameter than you in the Axial plane lying diameter, the Rotor chamber has a circular cylindrical circumferential shape.
  • the inflow and outflow are the Rotor chamber in one of the two symmetrical segments of the Rotor chamber provided by the lying in its axis Axial plane are defined.
  • control rings can be made of resiliently elastic Have material existing casing or strapping or the ring body of the control rings is radially resilient as a whole made elastic.
  • a rotor is designated, which is on a drive shaft 12 is rotatably mounted.
  • the rotor 10 is within a an undrawn inflow and an outflow connected rotor chamber 15 of a stator 16 arranged in the end walls of the drive shaft 12 is mounted.
  • a disadvantage of this known pump construction is that the radial distance between the outer wing edges 50 of the Rotor blades 30 during a rotor rotation angle of 180 ° in Direction of delivery of the rotor 10, due to the Eccentricity of the rotor 10 given kinematic Conditions over a 90 ° sector of the rotor chamber 15 first enlarged and then again accordingly downsized. This change in the radial wing spacing is indicated in Fig. 1 by dash-dotted lines.
  • Fig. 2 illustrates how this enlargement of the Radial distance of the outer wing edges 50 to the peripheral wall 44 the rotor chamber 15 in a first embodiment of the Invention is avoided.
  • the rotor chamber 15 in one through the maximum and minimum radial position of the rotor blades 30 in Rotor 10 defined an axial plane a-a with a diameter b, which is larger than a perpendicular to this diameter b Diameter c.
  • a-a with a diameter b
  • Diameter c a perpendicular to this diameter
  • a vane pump according to FIG. 3 becomes an increase in the radial distance of the outer Wing edges 50 to the peripheral wall 44 of the rotor chamber 15 thereby avoided that its peripheral wall 44 is circular cylindrical and the diameter d of the guideways 59 perpendicular to that through the maximum and minimum radial position of the rotor blades 30 in Rotor 10 defined axial plane a-a is correspondingly larger as a diameter e lying in this axial plane a-a.
  • the guideways 59 (see Fig. 5) for the rotor blades 30 by the outer peripheral surface of two control rings 66 and 68 are formed. These are from the Drive shaft 12 interspersed with radial play, each in an end-side depression of the rotor 30 is preferably such used that they are not with the end walls of the Pump bearing housing 20 are in contact.
  • the rotor blades 30 rest with their lower wing edge 70 (FIG. 5) in the area of their Wing end pieces each on one of the control rings 66 and 68 on the rotation of the rotor 10 with this turn along.
  • both control rings 66, 68 have one, for example Metal or plastic existing ring body 72 on the either with a casing or strapping 73 elastic material, such as suitable plastic or rubber, is provided or the ring body as a whole radially resilient is elastic.
  • the outer ring diameter and the dimension of the Rotor blades 30 are in the radial direction to the drive shaft 12 in this case preferably dimensioned so that the rotor blades 30 constantly with suitable radial preload or full of the peripheral wall 52 of the rotor chamber 15.
  • At 74 he is Inflow and at 76 the outflow of this vane pump designated.
  • the rotor shaft 12 can be supported by the stator 16 uncouplable and this relative to the rotor 10 in one Bearing housing to be adjustable radially to the shaft axis 12. This can be manual, depending on speed, pressure or flow rate respectively.
