Definitions

  • the invention relates to a cylindrical rotary valve with a seal for piston engines which has, - at least one opening running transversely to its longitudinal direction and a circumferential groove for each sealing ring on each side thereof, at least one groove on the wall of the bore receiving the rotary valve is provided, in each of which a seal is arranged, which can be pressed with an end face by spring force against the outer surface of the rotary valve.
  • valves which effect the gas exchange.
  • a complex mechanism is required, which generally consists of a camshaft with a drive, tappets, rocker arms, valves and valve springs.
  • valve overlap both valves are slightly open at the same time - is off there is sufficient space for the valve disk.
  • valve disk Therefor wells are superiors in the piston crown see ', the edges but overheated and can give rise to such ignitions.
  • the measures just described hit the valve disc against each other and thus render the engine unusable.
  • the aim of the invention is therefore to provide a rotary slide valve with a seal, which provides both a perfect seal and also prevents the slide valves from jamming in their bores and avoids the deficiencies of the known constructions.
  • the cylinder 1, the piston 2 with connecting rod 3 and the cylinder head 4 with spaces 5 for the coolant are shown in a simplified manner.
  • 6 is the inlet channel
  • 7 is the outlet channel.
  • 8 means a threaded hole for inserting an injection nozzle or a spark plug.
  • the two rotary valves are designated 9 and 10, 9 being the inlet rotary valve and 10 the outlet rotary valve.
  • the directions of rotation of the two sliders are indicated by arrows.
  • a chain can be provided to drive the rotary valve, which is placed over a sprocket on the crankshaft and over a sprocket on each rotary valve.
  • the rotary valves are driven by the crankshaft in a 4: 1 ratio, which means that they only run at a quarter of the crankshaft speed.
  • the rotary valves 9, 10 consist of solid material, e.g. 1 and 2 have an opening 12 running transversely to their longitudinal or rotational axis.
  • a beveled or poorly heat-conducting material e.g. ceramic material to use.
  • other material e.g. Sintered material to use.
  • the material can also be hardened or coated.
  • cylindrical bores 14, 15 are provided for receiving a rotary valve each. These bores 14, 15 are connected to the combustion chamber 13 via channels 16, 17, which are kept very short to keep the overall combustion chamber small.
  • the two bores 14, 15 are somewhat larger than the associated rotary slide valve, so that it cannot rest against the inner wall of the bore.
  • Each of the channels 16, 17 is surrounded by a circular groove 18 and 19, which starts from the respectively associated bore 14 and 15 for the respective rotary valve.
  • a sealing ring 20 or 21 is inserted, which has a flat end face 22 in FIG. 1 and one after one Has cylindrical surface corresponding to the lateral surface of the rotary valve extending end face 23 (see also Fig. 3, 4).
  • springs not shown in FIG. 1
  • the sealing rings 20, 21 are pressed against the lateral surface of the associated rotary valve in the area of the opening 12 thereof.
  • a rotary valve is shown in view. It consists of a full cylindrical body 30 with the transverse opening 12. A circumferential groove 31 is provided on each side of the opening 12 for receiving a piston ring-like, split sealing ring 32, which has the task of dissipating the heat from the rotary valve to the housing. A ball bearing 35, 26 is seated on each of two journals 33, 34. With these bearings, each rotary valve is supported in the bore 14 or 15.
  • the pin 34 is extended and carries a driving sleeve 37 which is connected in a rotationally fixed manner to the rotary valve by means of a spring 38.
  • a sprocket 39 is seated on the elongated pin 34, which is connected to the driving sleeve 37 by a dowel pin 40 in a rotationally fixed manner.
  • the parts __3ß, 37 and 36 are held against the body of the rotary valve by a nut 41 via a washer-42.
  • the sealing ring 20 (or 21) also shown in FIG. 2 and shown enlarged in FIGS. 3 and 4 has, as already mentioned, an end face 23 which is adapted to the jacket of the associated rotary slide valve and which extends after a cylinder Running layer be coated, as well as the jacket of the rotary valve with such an abrasion-resistant and low-friction coating can be seen.
  • the other end face 22 of the diaphragm ring 20 (21) is flat and, in the example shown, has four axially parallel Saok bores 44 which serve to accommodate helical compression springs 45 (FIG. 2), which are supported at the bottom of the groove 18 and 19 and press the diaphragm ring against the associated rotary valve.
  • Another blind bore 46 serves to receive a pin, not shown, held in the base of the groove 18 (19), which ensures the correct insertion of the sealing ring into the groove.
  • annular groove can be provided in the flat end face 22 for receiving a wave spring made of wire. It is also possible to have an annular wave spring act directly on the surface 22. Of course, other suspensions can also be provided.
  • FIG. 5 Another type of formation of the rotary valve is shown in FIG. 5.
  • a solo rotary valve 9 (or 10) has two, possibly also a plurality of, openings 12, 12 'of different cross-sectional shape and cross-sectional size and can be axially displaced from the outside by means of a device, not shown, even when the engine is running. It is thus possible to have another of the openings 12, 12 'come into effect by axially adjusting the rotary slide valve.
  • a groove 31 with a sealing ring 32 can also be provided between two of these openings; such an embodiment is in Figure 5 illustrates.
  • two, possibly also several, mutually concentric sealing rings are provided instead of the single sealing ring.
  • Each of these. Rings is held in its own groove. It is also possible, for example, to arrange a sealing ring on the inlet side, on the exhaust side, which is much stronger, above all thermally highly stressed, to attach two or more concentric diaphragm rings.
  • the arrangement of several concentric sealing rings is particularly important for large motors, i.e. in connection with rotary valves of larger dimensions.
  • the contact pressure for each individual ring can be smaller than it would be if only one ring was arranged. It is also possible to make the contact pressures of the individual rings of different sizes, for example the largest for the innermost ring and ever lower for each further ring lying on the outside. This measure can be achieved in a very simple manner in that all pressure springs for the rings of different sizes are of the same strength and are present in the same number.
  • the grooves with the sealing rings located therein can also be provided at other points in the bore receiving the rotary slide valve, ie they do not have to surround the channels running between the rotary slide valve and the combustion chamber.
  • they can be arranged around the channels leading away from the rotary valves; they can also be used between the channels mentioned above lying places, and also at opposite points. In such a case, the sealing rings would be pressed against the rotary valve from above and from below using the illustration according to FIG. 1.
  • roller bearings for the rotary slide valves provided in the exemplary embodiments described
  • plain bearings can also be used as well.
  • the springs, which are used to press the sealing rings against the rotary valve can also be used by others directions to be replaced; it can be provided that the sealing rings are pressed against the rotary valve by oil pressure.
  • each of the sealing rings 20, 21 a circumferential sealing ring 20A or 21A is provided, which sits in a groove 18A or 19A of the outer wall 18B or 19B of the sealing ring 20 or 21.
  • a circumferential sealing ring 20A or 21A is provided, which sits in a groove 18A or 19A of the outer wall 18B or 19B of the sealing ring 20 or 21.
  • several coaxial circumferential sealing rings 20A or 21A can also be assigned to each sealing ring 20 or 21.
  • Each of the sealing rings mentioned can also be provided with at least one circumferential sealing ring on the outside or on the inside or on both sides when concentrically arranged. There is also the possibility that only some of the sealing rings can be provided with at least one circumferential sealing ring of the arrangement according to the invention.
