The invention relates to an oiler that can be used as an exchangeable, elongated cartridge parallel to the compressed air flow into a compressed air duct. wherein the cartridge has a housing, the side wall of which is penetrated by holes. l-Jeaia ssaehfolgoKsd spoken by compressed air, so therefore sum Auadruaek is gsbrasht that Preßluftmaschinen! ©! ^ d®r invention represent the ifaiuptaHiweiidiHiigsfe © ^ ©, Di © invention is ab®i? ssaiäürlisfe can also be used on all other rait-like Drackmifctölß aiag © tr! levels Maschiuan.

wall of the cartridge should travel with it. The pressure of the compressed air builds up through the holes also inside the cartridge housing, a pressurized air cushion forming over the unused liquid oil. During operation, the compressed air penetrating the cartridge from the outside inwards interferes with the escape of oil and as a result the oil release to the compressed air coming to the compressed air line is too low. In shutdown of Preßluftzufutir However, the opposite effect occurs because of the shutdown of the pressure outside of the cartridge is less than in the same and the Oilers now that he .not more to oil begins to strong oil ,, until a pressure balance betw la ah ® η the interior and Xu'3eron the cartridge is made. This leads to undesirably high oil losses. Another disadvantage of the known oiler is that the cartridge is very difficult to refill when the oil it contains has been used up. Since the cartridge © contains liquid oil, the holes in the wall of the cartridge housing must be relatively small and, as a result, it is extremely difficult to fill the interior space with oil.

The object of the invention is to avoid the disadvantages outlined. Erfindungegemäß this object is achieved in an oiler of the type specified characterized _s that the interior of the housing and an old cotton is filled in the contact rod wick completely with durohtränkter oil cotton

and that the end of the wick passes through an opening in the downstream side At the end of the housing to the outside.

According to the invention, the oil pi-trono does not use oine f.Ii) oil filling. «Ondorn drvr. Oi i3t zvi.ichen v / atie or the like finely divided. As a result, sic'-i cannot build up a closed air cushion over a closed body of liquid inside the cartridge, but air and oil are both evenly and finely distributed over the entire interior of the cartridge.

It can be demonstrated by experiments that the oil is released solely at the end of the wick that protrudes through the end of the cartridge on the abatromus side. These phenomena are evidently a consequence of the fine distribution of the air inside the cotton-wool-oil mixture, which is probably also responsible for the fact that the pressure equalization between the interior of the cartridge, which is under higher pressure, and the outside of the cartridge, which is under lower pressure after switching off the compressed air supply practically without

The (the exact physical connections of these ErseheIrjungoii are not fully clarified, but it can be proven by testing with the 01, that the oil is only released through the end of the wick and over long periods of time and many on-hold and off-hold operations remains largely uniform.

The retrieval of the used cartridge is also extremely easy with the cartridge according to the invention, since it only has to be removed from the compressed air duct and placed in oil for some time. The cotton wool sucks in the oil extremely quickly through the holes in the side wall, which seems to have the same physical reasons as the above-described rapid pressure equalization between inside and outside, which does not affect the oil content of the cotton wool.
