Definitions

  • the invention relates to a sealing system for a heat engine or work machine.
  • the sealing system seals a gas-filled space, the gas pressure in that space pulsating (i.e. swelling or fluctuating) or constant against a moving one or resting body that covers part of its circumference or surface with this gas space surrounds, and avoids all of the design disadvantages listed below of the already existing Sealing systems.
  • This sealing system is used in heat engines (piston engines, Turbines) and working machines (compressors), in which a gas-filled space according to the above Criteria should be sealed.
  • Sealing systems for the above-mentioned purposes are, for example, for slide controls for Internal combustion engines are known and in the publications DE 37 20 082 A1 (Krüger), DE 37 20 084 A1 (Krüger), EP 0 624 718 A1 (Coates), FR-A-2 429 323 (Honda), NSU seal, automotive engineering Newspaper, No. 6, 1954, page 146, picture 7c, as well as DVL-WVW rotary valve control, Motortechnische Zeitschrift, No. 9, 1960, page 363.
  • the invention strikes Sealing system in front, consisting of a closed slide ring, one with an open joint Sealing ring and a device that the sealing ring with its surface against the surface of the Sliding ring presses, whereby the sliding ring with its sliding surface against the tread of the to be sealed Body is pressed, the slide ring along a perpendicular through the Center of gravity of the sliding surface axis in a recess in the fixed housing is guided, the sealing ring in its radial wall thickness regardless of the outer diameter the slide ring is designed and is guided coaxially to the slide ring in the housing, and the device the sealing ring with a gas pressure that is constant or freely adjustable in its amount independent force pushes against the slide ring.
  • the sealing system shown in FIGS. 1A to 1C consists of a slide ring 15, a Sealing ring 5 and a device 6, which the sealing ring 5 with a constant or arbitrarily adjustable, force independent of the gas pressure against the slide ring 15.
  • This device 6 is exemplified here by a spring.
  • the slide ring 15 is a closed ring which is perpendicular to the axis 1 through the Center of gravity of the sliding surface 4 leads, rotationally symmetrical, elliptical or arbitrarily point symmetrical can be, as illustrated in Figures 3 to 5.
  • the contour of the face 4 is adapted to the tread 3 of the body 2 to be sealed.
  • the sealing ring 5 has a radial joint 12 and is thus an open ring.
  • the sealing ring 5 lies with its end face 10 on the end face 14 of the slide ring and its inner surface 9 is aligned with the inner surface 11 of the slide ring 15.
  • the gas pressure acts on the end face 8 and the inner surface 9 of the sealing ring 5, as a result of which this axially presses with its end face 10 against the end face 14 of the sliding ring 15 and this with its end face 4 is pressed against the tread 3 of the body 2 to be sealed. While any movement of the body 2 moves its tread 3 only tangentially to the sliding surface 4 of the sliding ring 15.
  • the pressure acting on the surface 9 spreads the sealing ring 5 radially, so that its outer peripheral surface 7 is gas-tight on the housing 13 and the axial Mobility of the sealing ring 5 is hindered. This will forward the on End face 8 of the sealing ring 5 exerted gas force on the slide ring 15 reduced.
  • the force that results from the gas pressure acting on the end face 8 also increases the sealing ring 5 attacking force of the device 6 is superimposed.
  • the axial displaceability of the sealing ring 5 and the sliding ring 12 in the recess 18 of the housing 13 ensures continuous contact with the surface 3 of the body to be sealed 2 and compensates for thermal expansion and wear on running surfaces 3 and 4.
  • FIGS. 2A, 2B and 2C is based on the embodiment according to Figures 1A, 1B and 1B, with the difference that instead of the spherical or cylindrical Tread 3 of the body 2 to be sealed, a flat tread 3 is provided.
  • a flat tread 3 is provided in your Structure and their functioning in these figures.
  • 1A to 1C and 2A to 2C illustrate a collar 19 on the housing 13 which the axial displaceability of the sealing ring 5 in the direction pointing away from the body 2 to be sealed Direction limited.
  • the fulcrum of the body 2 is designated by the reference number 20.
