- the outlet valve 5 has a valve seat 6 which cooperates with a valve seat provided in the region of the outlet opening 4 and which is attached to the lower end of a spindle-shaped valve stem 7.
- An outlet channel 8 adjoins the outlet opening 4 and is open with respect to the combustion chamber 3 when the outlet valve is lifted from the associated seat and vice versa.
- the exhaust valve 5 is associated with a mounted on the cylinder head 2 exhaust valve housing 9, which contains the exhaust passage 8. Attached to the valve housing 9 is a seat ring 9a which engages in the cylinder head 2 and which contains the valve seat which delimits the outlet opening 4.
- the valve housing 9 further includes a shaft 10 of the outlet valve 5 associated with the guide bushing 10. This is coaxial with the outlet opening 4 and extends from the puncture of the valve stem 7 through the upper wall portion of the outlet channel 8 to the upper portion of the valve housing 9.
- the guide bush 10 passes through the upper wall region of the outlet channel 8, so that the annular gap 11 between the mutually facing guide surfaces of the guide bushing 10 and the shaft 7 of the exhaust valve 5 is accessible from the outlet channel 8 ago.
- the valve stem 7 passes through the guide bushing 10 and protrudes with its guide sleeve 10 projecting portion into a received on the valve housing 9 structure 12, which includes an outlet valve 5 associated actuator for effecting the opening and closing movement.
- the actuating device contains a feed device designed as a hydraulic unit and a resetting device designed as an air spring.
- the structure 12 has a two-part housing, the upper part 12a of which the hydraulic unit forming the feed device and the lower part 12b of which contain the air spring forming the return device.

- the provided below the hydraulic unit, acting as a return spring air spring comprises a penetrated by the valve stem 7, on this fixed piston 15, which encompasses a work space 17 enclosed by a collar 16 integrally formed on the lower part 12b and which can be acted on with compressed air via a compressed air line 18 connected to a compressed air source. To reduce excess pressure in the working space 17, this is provided with an outlet, to which an adjustable safety valve 19 is assigned, which opens at a set pressure.
- the leakage oil escaping from the hydraulic unit located above the intermediate space 20 enters the intermediate space 20, from which an unpressurized return line 21 can exit. This expediently adjoins the bottom of the region of the intermediate space 20 that surrounds the collar 16.
- the acted upon by compressed air working chamber 17 is sealed relative to the annular gap 11 between the facing guide surfaces of the valve stem 7 and guide bush 10 by a sealing ring 22 at least one sealing device.
- the sealing device may be formed as a stuffing box containing at least one sealing ring 22.
- a sealing ring 22 is provided in the embodiment according to Figures 1 and 2.
- sealing rings 22, 23 arranged one above the other are provided.
- annular gap 11 between the mutually facing guide surfaces of the valve stem 7 and guide bush 10 is open to the outlet channel 8, there is a risk that combustion residues penetrate into the annular gap 11, which leads to damage of foundedsfizzen and in particular the sealing ring 22 and the lower that is, the sealing channel 22 facing the outlet channel 8 can lead to the sealing device.
- the annular gap 11 is pressurized with oil from above. This can emerge at the lower end of the annular gap 11 in the outlet channel 8, where it can burn.
- the leakage oil escaping from the pressure chamber 14 of the hydraulic unit primarily serves to feed the oil reservoir 24.
- the aforementioned leak oil drips, as already mentioned above, into the intermediate space 20 and at least reaches it partially on the top of the piston 15 of the air spring assembly. From here, the leakage oil reaches the working space 17 in the region of the circumferential piston surface, where it can collect on the bottom side and form the oil reservoir 24, as can be clearly seen in FIG.
- a supply line 25 which opens into the lower region of the pressure chamber 17.
- the supply line 25 may be associated with an external oil source. But it would also be possible to simply divert the oil supplied via the supply line 25 from the oil supplied to the pressure chamber 14 of the hydraulic unit.
- the working space 17 can also be charged with oil mist.
- the compressed air line 18 may be associated with an oil mixing device 26. The entrained by the compressed air oil is sprayed in the form of an oil mist in the working space 17. The oil mist precipitates on the walls and drips off into the oil reservoir 24.
- the safety valve 19 controls a flow path leading from the oil reservoir 24 to an oil return line 21.
- the safety valve 19 is associated with a projecting into the oil reservoir 24 overflow pipe 27, the upper end forms an overflow edge and accordingly sets the height of the oil level in the oil reservoir 24.
- the safety valve 19 can be set in this embodiment, regardless of the height of the oil level in the oil reservoir 24 to a fixed pressure, which facilitates the setting. Nevertheless, the oil reservoir 24 results in a constant oil level.
- the overflow edge formed by the upper end of the overflow pipe 27 is of course higher than the sealing ring 22 so that it is reliably flooded with oil.
- the sealing ring 22 receiving the guide bushing 10 is supported with an upper flange 10 a on the valve housing 9.
- the sealing ring 22 is inserted into an upwardly open annular groove of the flange 10 a, which is overlapped by a cap 28. This is provided in a below the oil level of the oil reservoir 24 and above the sealing ring 22 located area with radial fürgangsaus principle 29, which accordingly lead from the oil reservoir 24 to above the sealing ring 22 located portion of the annular gap 11, whereby a flooding of the sealing ring 22nd is favored with oil.
- the radial recesses 29 may be formed as bores or cutouts, etc.
- the supply line 33 like the supply line 25 of the embodiment according to FIG. 1, can be connected to an external supply Oil source etc. may be connected, again in the example shown is leak oil, as already mentioned, for feeding the oil reservoir 32 use.
- This drip edge 34 is here underlined by a collecting channel 35, from which the supply line 33 goes off.
- the oil groove 32 containing annular groove 31 extends to the top of the cap 28, the upper side accordingly forms an overflow edge, through which a constant oil level in the oil reservoir 32 is ensured.
- the overflowing oil enters the region of the bottom of the working space 17, from where the controlled by the safety valve 19 flow path, can be removed via the excess oil.
- the safety valve 19 can be adjusted without regard to the oil level in the oil reservoir 32, which simplifies the setting. An overflow pipe upstream of the safety valve 19 is not required in this embodiment, which is often advantageous for reasons of space.
- two sealing rings 22, 23 arranged at a distance from one another are provided.
- the limited by these two sealing rings 22, 23 portion of the annular gap 11 is applied to form an oil reservoir 36 with oil.
- the oil is applied in continuous operation.
- the said annular gap section is accordingly connected to a supply line 37 and a disposal line 38.
- the supply line 37 may be connected to an external oil source.
- the disposal line 38 can open into a non-pressurized oil return line.
- the sealing ring facing the outlet channel 8 in this case the lower sealing ring 22, ie the lower sealing ring of the sealing ring arrangement, is reliably flooded with oil, whereby the annular gap 11 is reliably supplied with oil.
- the Zwangssbeetzschiagung the oil reservoir 36 results in a particularly high reliability.
- the application of the annular gap 11 to the oil entering via the sealing ring 22 prevents a reliable penetration of combustion residues into the annular gap 11.
- the Ringspalti 1 are additionally acted upon with compressed air, which is suitably fed below the sealing ring 22, as indicated in Figure 1 by a positioned below the sealing ring 22, the annular gap 11 leading line 39 is indicated. It would also be conceivable to supply oil mist and / or additional oil via such a line.
- the oil flow through the annular gap 11 may be comparatively low and may be about one liter per day in a two-stroke large diesel engine.
- the escaping from the hydraulic unit leak oil is about 10 liters per day in such an engine and therefore can easily cover the oil consumption to supply the annular gap 11 of the.
- the oil supply to the annular gap 11 takes place on the sealing ring 22 and can be influenced by its geometry. It can be assumed that between the sealing ring 22 and the valve stem 7, a hydrodynamic lubricating film is formed, the thickness of which depends essentially on the geometry of the sealing ring 22 and other fixed parameters such as the relative speed. A wedge-shaped inlet of the gap between the relatively moving surfaces favors the formation of a lubricating film. Likewise, the width of the contact surface adjoining the inlet influences the thickness of the lubricating film.
- the sealing ring 22 has a symmetrical to a horizontal plane of symmetry cross section with wedge-shaped inlet 41 on both sides and a broad contact surface 40.
- the wedge shape of the inlet has a comparatively large wedge angle.
- the contact surface 40 is wide and extends over almost the entire height of the sealing ring 22.
