Definitions

  • the seal between the vanes outer surfaces and the inner surface of the housing is crucial in that the lower the gap between the oscillating and rotating piston surfaces and the inner surface of the housing, the higher the efficiency the rotary piston machine can be recognized.
  • the subject of the invention is therefore a rotary piston machine of the type mentioned in the introduction, which has the mower cell mentioned in the c a n c e s e c e s of the entry n e r c h e s e.
  • the wells may be aligned on the cylindrical peripheral surfaces of the rotary vane in an analogous manner with its diagonal or with the respective longer axis in the direction of the piston-wing movement, however, experiments have shown that this is not so striking positive effect on the cylindrical peripheral surfaces has, as with the sealing moderately difficult to control flank surfaces of the rotary vane.
  • the claim 7 indicates the preferred within the scope of the invention distances of the sealing webs from each other, in which case the distances between the center lines of each adjacent sealing webs are each meant here.
  • the claim 8 details regarding favorable widths of the network-like interconnected sealing webs can be seen.
  • the claim 9 calls for a high sealing effect favorable ratios of web width to mutual web spacing.
  • the claim 10 indicates the sealing effect of the lubrication / sealing network forming sealing webs effective sealing land heights.
  • the claim 11 is to be taken in the context of the invention, a particularly advantageous cross-sectional shape of the new lubrication / sealing network forming sealing webs.
  • claim 12 describes the sealant / lubricant mass preferably to be used for the sealing webs. This is essentially a mass or mixture of powder graphite with a thermostable and thermally curable
  • Resin which is applied to the surfaces to be coated, in particular printed, and cured there under heat treatment.
  • sealant / lubricant mass in the inventively provided arrangement in addition to the high sealing effect as a result of multiplied labyrinth seal effect has such a high lubricant quality that it can serve in the event of the occurrence of a lubricant shortage quite as emergency lubrication.
  • Fig. 2 shows one of the blades of the rotary piston machine with the new surface treatment in more detail and Figs. 3a to 3c details of the new lubricant / Dichtffenbeetzstoffung the rotary vane.
  • Fig. 1 shows a known rotary piston machine 100 with the inside of the housing 10 relative to each other oscillating rotatable rotary lobes 20, 30 and between them forming, during the work cycles variable size having working chambers 8.
  • Countersinks 91 are disposed between the sealing lands 90 surrounding each of them so that a large number of diagonals of the squares are oriented substantially in the direction of the rotary vane movements.
  • FIG. 3c shows the preferred, approximately trapezoidal cross-sectional shape of two of the sealing webs 90 with a depression 91 delimited by them, in which e.g. can collect the lubricant, in particular lubricating oil, and it is there to see the height hs of the sealing webs 90, which is advantageously 0.02 to 015 mm and their width bs, which is advantageously 0.5 to 1.5 mm. Arrows there is still the direction of the oscillating rotor movement of the rotary wing 20, 30 indicated.

Abstract

L'invention concerne un moteur à pistons rotatifs comprenant une pluralité de pistons-palettes rotatifs. Un revêtement d'étanchéité de fente réalisé dans une matière produit d'étanchéité/de lubrification (DS) structurée, contenant du graphite et de grande stabilité est appliqué de manière fixe sur les surfaces périphériques (26, 36) des pistons-palettes rotatifs (20, 30) et sur leurs surfaces de flancs (27, 37), des deux côtés. Ce revêtement est formé d'un réseau d'étanchéité/de lubrification (9) qui est appliqué sur les surfaces des pistons-palettes rotatifs, est composé de segments d'étanchéité (90) en relief se croisant et est réalisé dans la matière produit d'étanchéité/de lubrification (DS). Entre les segments d'étanchéité, sont disposés des enfoncements ou des creux (91) qui vont jusqu'aux surfaces, dépourvues de revêtement, des pistons-palettes rotatifs.
