Definitions

  • the invention relates to a housing, constructed for receiving and storing a micropump, for example a fluid pump, which works on the principle as described in WO-A 97/12147 ; this document is explicitly referred to when operating this type of pump or a corresponding fluidic motor type, in particular page 1 (paragraph 2), page 5 (paragraph 4) and page 6 (last paragraph) and page 7 (first paragraph).
  • a micropump for example a fluid pump
  • An inner wheel and an outer wheel are designed to mesh with one another and are arranged; both the inner wheel and the outer wheel are rotatably arranged in a sleeve, cf. there Figures 1, 1a, 2 and 2a and Figures 3a, 3b and 3c.
  • the inner wheel is coupled in a torsionally rigid manner to a shaft (there 50).
  • the axis of the outer wheel and the sleeve is offset relative to the axis of this shaft, so that there is an eccentric rolling of the inner wheel with its outwardly facing teeth on the inwardly directed gentle, in particular cycloidal, tooth structure of the outer wheel and according to the number of teeth dimensioned form axial sealing lines, each defining a delivery chamber in pairs.
  • these delivery chambers expand in the direction of rotation on the suction side, take up fluid there and deliver it via an imaginary central plane running through the axis to the pressure side, on which the delivery chamber that has just passed steadily decreases in the course of further rotation until it practically goes to zero and is guided back to the suction side on the opposite side of the central plane.
  • the pump chamber mentioned begins to open continuously with the rotary movement, so that the cycle closes.
  • the movement described for a delivery chamber applies simultaneously to all existing delivery chambers, which at the moment each have a different volume between a respective pair of sealing lines, so that when the pump is operating there is a highly uniform delivery flow with a high ability to miniaturize the entire microsystem structure ,
  • a sleeve is selected as the bearing, into which sleeve insert parts (there 41, 42) are used on both end faces of the inner wheel and outer wheel, which are used for mounting the shaft and for specifying the inlet kidney and outlet kidney (specifically explained there in FIG. 8, with reference to inlet kidney 41k and outlet kidney 42k).
  • the inlet kidney is offset by 180 ° from the outlet kidney (mirrored), but at two opposite ends, so that there is an axial fluid flow from the inlet kidney to the outlet kidney via the constantly changing volume of the delivery chambers as described above.
  • such a pump can also work with a U-shaped fluid flow, in which case the inlet and outlet kidneys are located on the same end face of the pump, only mirror-inverted by 180 ° (mirrored on the median plane that runs through the axis).
  • a microsystem is to be inserted or inserted into a housing structure, so that it is securely and precisely mounted, but at the same time there are all connection options which provide the fluid inlet, the fluid outlet and the coupling of the mechanical drive source for rotating the pump shaft (for an interior - or outer wheel pump) or the output shaft (for a fluidic motor) or the metrological side (for a fluidic sensor) for a volume flow.
  • a possible housing shape (housing) for receiving such a micropump is described in a data sheet "Pump head mzr® -4600” from Hydraulik Nord Parchim Mikrosysteme GmbH.
  • This pump head shows a shaft that faces the front Coupling of a motor protrudes.
  • Five disc-shaped elements form as Cylinder elements the housing structure, starting with a housing shaft seal, a balance kidney plate and a rotor seat plate, followed by one Fluid guide and an end cover.
  • the rotor holder has a thickness (or Height or strength, which runs in the axial direction), which with the axial dimension of Outer wheel and inner wheel match as shown above.
  • a hole is provided which is opposite to the axis of the shaft Drive of the inner wheel is offset eccentrically, so that the outer wheel Micro gear pump is mounted off-center in the opening of the plate and the top described mode of operation of the constantly expanding and on the opposite side results in continuously reducing the volume of the delivery chambers - if the shaft is driven by a rotary drive.
  • the compensation kidney plate and the fluid guide plate which is directed towards the rotor Input kidney and exit kidney described above on the fluid supply side and mirror-image compensation kidneys to create a hydraulic Have equilibrium on the opposite side. This results in a U-shaped Fluid flow from the inlet to the rotating kidney via the inlet Pump chambers, towards the outlet and back to the one in the data sheet mzr® -4600 radially led outlet.
  • DE-B 33 10 593 (White) shows a housing structure (housing) for a pump arrangement (there, Figure 1, reference number 22) which, together with a wobble rod, realizes an eccentrically operating gerotor. At the end not penetrated by the shaft there is a central outlet and, on the other hand, an inlet radially offset, while intermediate plates having a plurality of channel segments (see FIGS. 2, 3, 4 and 5) are provided in between.

  • FIG. 7 An additional plate 32, which is arranged on the other side of the receiving plate 30 shown in FIG. 6 with an eccentric opening 30a, is shown in FIG . 7 .
  • the axes AA and BB have to be rotated by 90 °, so that the kidneys lie directly one above the other.
  • These compensating kidneys are located directly opposite the inflow and outflow kidneys 41k and 41k '. They have the same shape, the same circumferential extent and also pass completely in the axial direction through the additional plate 32, with which they form both an axial channel segment and a circumferential channel segment. However, the axial channel segment ends on the surface of the additional plate 32.
  • the first further plate 20 which was already explained in detail with reference to FIG. 4 , is shown in a top view and in a sectional view AA in FIG. 8 for additional illustration.
  • the sectional illustration illustrates the flow path of the fluid F with the U-shaped deflection of the microsystem shown in dashed lines.
  • Each of the fluid-directing composite channel segments is composed of at least one axial segment 20a and one radial segment 20r. The radial segments can still be slightly inclined in the circumferential direction, as can be seen from the top view.
  • the radial segments can be completely milled out or elongated openings produced by wire erosion, which then realize both an axial inflow 20a and a radial fluid deflection following the elongated hole.
  • housing structure G to which connections 60, 61 lead.
  • the shaft 50 protrudes in the direction of a motor M to be flanged, which in turn has a shaft journal 59.
  • the coupling of these two shaft journals, without radial misalignment and axially exactly aligned, runs via a coupling piece 80, which has a precisely predefined bore 81, 82 on both end faces, which is usually precision-machined as a round opening.
  • a respective collar piece 71, 72 is arranged on the end face of the housing G for the microsystem and on the end face of the motor M so that they fit exactly into the bores 81, 82.
  • the cylindrical openings 81, 82 are precisely aligned with one another, and if the two functional elements M, G are inserted into these openings, the axes 59, 50 are aligned.
  • a shaft connector 58 is attached, which is first loosely plugged onto the shaft end 50 in order to then be pushed together with the latter into the receptacle 81 until the collar 71 comes to lie closely against the receptacle structure G in the receptacle 81.
  • the motor M is plugged in from the other side, in which the collar 72 is fitted into the opening 82 in the same way.
  • the housing structure G is provided with an outer surface that appears cylindrical.
  • a polygonal outer surface is also possible here, which also has side surfaces which run essentially uniformly in the axial direction in order not to have any steps directed in the axial direction.
  • Bores 81.82 have a different diameter, adapted to the respective frets 72.71 of the functional parts G, M intended for them.
  • the plate-shaped layer structure in FIG. 2 not only shows panels of the same thickness (thickness), but it would be beneficial to all panels to be made from the same layer thickness.
  • 3 can be seen schematically that the channel through which these plates are of substantially equal strength runs, has essentially the same cross-section along its extent, to avoid dead volumes.
