These two housing elements 14 and 16 are attached to one another to a rotation axis R, for example, perpendicular separating plane E together and connected to each other, for example, by gluing, soldering, welding or other fluid-tight manner.

  • the slider 50 also has the function that with progressive movement of the annular piston 24 by the system of the slider 50 on the outer surface 54, the available volume of the delivery volume range is getting smaller and thus the fluid contained therein must forcibly enter the outlet channel 46.
  • the slider 50 has an extension length in the direction of the rotation axis R, which approximately corresponds to the extension length of the annular piston 24 and the delivery volume regions 34.
  • an electric drive assembly To drive the ring piston 24 for rotation about the axis of rotation R, an electric drive assembly, generally designated 50, is provided.
  • the stator arrangement 54 has four armature / coil areas 56, 58, 60, 62 arranged at an angular distance of 90 ° from one another. Each of these armature / coil areas 56, 58, 60, 62 can be energized by energization so that either a magnetic north pole or a magnetic south pole is generated in its radially outer and the Gescouseinnenwandung 20 immediately adjacent area.

These may be embedded in the building material of the annular piston 24 and, for example, may also provide a portion of the inner circumferential surface thereof due to their curved configuration.
  • the number of permanent magnets corresponds to the number of armature / coil areas and that the circumferential extent of the permanent magnets also corresponds approximately to the circumferential extent of the radially outer areas of the armature / coil areas.

  • the permanent magnet 66 is the armature / coil portion 56 radially outwardly opposite and approximately centered in the circumferential direction to this.
  • Due to the in Fig. 1 Also identifiable symmetrical configuration is therefore each of the armature / coil areas 56, 58, 60, 62 in the circumferential direction approximately centrally each one of the permanent magnets 66, 68, 70, 72 opposite.
  • a magnetic interaction is generated which generates a propelling force in the clockwise direction.
  • the magnetic North pole of the permanent magnet 66 from the armature / coil portion 56 is attracted while the magnetic south pole of this permanent magnet 66 is repelled.
  • a corresponding interaction is also generated in the other pairings.
  • the annular piston 24 is set in motion, so that the circumferential centering of the paired permanent magnets and armature / coil areas is canceled.
  • the magnetic south pole of the permanent magnet 66 now moves closer to the magnetic north pole of the armature / coil region 58 and is attracted by this stronger.
  • the magnetic north pole of the permanent magnet 58 is attracted by the magnetic south pole of the armature / coil region 60, etc.
  • stator assembly and in a corresponding manner, the rotor assembly with a different number of stator / coil areas or permanent magnets, but preferably the number of permanent magnets and the number of anchors / Coil areas corresponds. The larger this number, the smoother the drive can be.
  • a configuration with only two armature / coil areas and correspondingly two permanent magnets is possible, which then have to provide the star-like configuration an angular distance of 180 °.
  • FIG Fig. 9 A modified embodiment of a conveyor 10 according to the invention is shown in FIG Fig. 9 shown.
  • the annular piston 24 has a larger number of elevation regions 28 and consequently also a larger number of delivery volume regions 34 formed in the circumferential direction therebetween.
  • a configuration with six elevation regions 28 following one another in the circumferential direction and correspondingly also six depressions 30 or delivery volume regions 34 formed between them can be seen here. This leads to a homogenization of the delivered volume flow.
  • the stator assembly 54 and the rotor assembly 64 are constructed in the same manner as described above. It can be seen that the number of land areas 28 is completely independent of the number of permanent magnets of the rotor assembly 64 and, correspondingly, the number of armature / coil areas of the stator assembly 54.
  • the annular piston 24 is mounted on the inner peripheral surface 32 of the housing outer wall 18.
  • the embodiment is such that the elevation regions 28 abut with their apices on this inner circumferential surface 32 and move in a sliding manner along this inner circumferential surface 32.
  • the medium to be delivered will provide a very beneficial lubricating effect here.
  • Radially inside the annular piston 24 then has a small distance to the outer peripheral surface 26 of the housing inner wall 20 in order to avoid constraints.
  • inlet channels 42 or openings 44 or / and a plurality of outlet channels 56 or openings 48 could then lie consecutively in the direction of the longitudinal axis, so that over a plurality of openings 44 distributed in the direction of the longitudinal axis or possibly a gap-like opening over the length of the annular piston 24 distributed more uniformly, the medium to be conveyed can enter into the delivery volume regions 34 and with appropriate design the outlet side can escape there.
