Definitions

  • the invention relates to an internal gear machine, in particular a Internal gear pump.
  • Such machines are numerous Publications known, for example DE 41 04 397 A1.
  • WO 95/12070 describes an internal gear machine having a longitudinally split Filler has.
  • the invention is based on the object, an internal gear machine which can be operated in both directions, and the can be installed in a closed system, and then, when the position of the pressure range in the pump changes.
  • the internal gear pump shown in Figure 1 comprises as essential Components a pinion 1 with an external toothing, a ring gear 2 with a Internal toothing, a filling of two filling pieces 3, 4, a Stopper pin 5 and a housing 6.
  • Pinion 1 is mounted eccentrically relative to ring gear 2. See the Center point M1 of the pinion and M2 of the ring gear. By the two Midpoints M1 and M2 are passed through a dot-dash line. This denotes a plane of symmetry, whose meaning is below yet to be received.
  • the crescent-shaped space between the pinion 1 and the ring gear 2 is of filled a filling.
  • the filling comprises the two filler pieces 3, 4.
  • the Stop 5 is mounted in the housing 6 with a certain amount of play. How one sees, the stop has two support surfaces 5.1, 5.2. The end faces of the two patches 3, 4 were supported against the support surfaces 5.1, 5.2.
  • the two filler pieces 3, 4 are also longitudinally in a conventional manner divided. They are thus constructed from an inner part 3.1, 3.2 or 4.1, 4.2. However, the filling pieces 3, 4 could just as well each consist of a single part.
  • the housing has two pressure ports 6.1, 6.2.
  • the two Pressure connections are on both sides of the symmetry plane 7.
  • the housing also has a leakage outlet 6.3. This is in the present case exactly in the symmetry plane 7.
  • the arrangement is made in such a way that the two filling pieces 3, 4 are symmetrical to the plane of symmetry 7. Also, the stopper pin 5 is arranged such that the symmetry plane 7th passes through it, and it into two symmetrical parts divided. As you can see, the plane of symmetry 7 passes through the tip the stopper pin 5, which formed from the two support surfaces 5.1, 5.2 becomes.
  • the housing 6 recesses 6.1.1, 6.2.1, 6.3.1. These are to the respective pressure connections 6.1, 6.2 or the leakage outlet 6.3 connected.
  • a Pump 10 according to the invention.
  • the pump 10 is part of a closed cycle. It also recognizes a hydraulic unit 11, comprising a double-acting piston 11.1 and a cylinder 11.2.
  • the piston 11.1 is displaceable in the cylinder 11.2 in both directions, depending after, with which of the two lines 12, 13 of the cylinder with Pressure medium is applied by means of the pump 10.
  • Pressure medium either in the line 12th or promoted to the line 13.
