Description

Device for checking the oil level in motor vehicle engines So far rooted for the brisk. Regularly required check of the oil level in the engines of Motor vehicles so-called oil measuring sticks are used, which are inserted into an opening in the engine housing or an oil filler neck. z. B. by simply plugging in or screwing in, are housed. To check the oil level, the oil dipstick must be in proportion awkwardly pulled or screwed out of the opening, from which during the When the engine is running, oil film distributed over the entire length of the rod, e.g. B. with a rag cleaned, eiyefiilrt completely into the opening and removed again for examination will. This is the only way to accurately check the oil level. Just as cumbersome must be used when refilling or refilling the cules in the container process. at With these many manipulations there is always the danger that by touching the 5lstick with the engine compartment inner wall of the latter dirt is detached and into the opening the oil container can get; even an unclean rag can cause it to be wiped off the 5les from the dipstick up (read, leave dirt behind and so contaminate the lubricating oil which is a considerable risk for the bearing points in the engine, in particular brings about a reduction in their service life.

It is also already known to separate an additional one from the oil pan provide a transparent oil container from which when the oil level drops in the Oil pan is automatically supplied again oil below a certain level of the oil pan. This facility allows in the simplest way to check the Otstandes in additional oil tank. However, it does not allow a reliable examination of the actual the oil level in the oil pan. In addition, this facility requires one high effort.

In order to avoid these disadvantages, it has already been proposed that the oil be in the range of the normal oil level a transparent or translucent oil level tube made of celluloid should be provided. These However, setup requires additional fittings and machining on the engine and therefore could not prevail over the simple oil measuring sticks.

Based on the last-named facility, the Invention of a device for testing the oil level in motor vehicle engines with a transparent top closed by a releasable lock Oil level pipe made of plastic on the oil pan of the engine, according to the invention it is proposed that the oil level pipe is designed as a filler neck, that also the plastic elastiscli is and the olefin filler neck with a pipe socket of the oil pan through Simply pushing one part onto the other is connected, with the seal through sufficient internal tension of the Plastic is achieved. The inventive Facility thus offers the possibility of testing the Ütstandes in motor vehicle engines after opening the engine compartment cover at a glance without any further action perform. Openings to the oil reservoir only need to be opened when changing the oil beb, bringing the risk of contamination of the moto. oil to the minimum possible is reduced.

Another essential advantage of the device according to the invention it should also be mentioned that due to the simple test possibility without any Experience has shown that the risk of soiling the person checking is less of a risk this oil level check is neglected than with the previously used ones, mostly unclean oil dipsticks is the case, the operation of which is often a certain Requires overcoming or the use of gloves or rags.

This in itself is an advantage to the known execution through the invention with the least amount of material and processing on the engine achieved by raucll from the well-known properties of modern plastics (lel) made and a simple and robust oil level indicator device is proposed otherwise required effort for fastening the oil filler cap on the motor housing is saved.

To identify the required oil level, in Ausgcsta. According to the invention of the oil filler neck with preferably in the manufacturing process attached Oil level brands, e.g. B. Elevations o (ie! R depressions on the outer surface, provided be.

In an embodiment of the invention, the oil filler neck can also have in the manufacturing process, attached ventilation pipe and fastening devices The oil filler neck should also go over the pipe neck of the Olwaime be gestüipt and so the connection of the oil filler neck with the inside of the container in the manner of communicating vessels.

Finally, the oil filler neck with a one-piece cap made of preferably red plastic to close oil-tight. the ül a collar provided at the opening of the Oleinffillstutzens is turned over.

In the drawing, the invention is based on an exemplary embodiment shown, namely the same shows an oil filler neck for a motor vehicle engine in view.

The oil filler neck 1 is together with the loading or. Vent pipe 2 and the fastening tab 3 from one piece @ made of transparent or translucent Made of plastic. On its outer surface are to fix the normal oil level Oil level marks 4 in the form of horizontally arranged, bead-like Queir strips attached in the manufacturing process, so that to check the oil level in the full container A quick glance at the oil filler neck is enough to make sure there is. the Oil level 5 at the height between the two oil level marks 4; stands and thus sufficient 01 available for engine lubrication. The connection of the oil filler neck 1 at the lower horizontally directed end with the one made of sheet metal, plastic or other Material existing pipe socket 6 of the oil tank and the ventilation pipe 2 with the pipe socket 7 is done by simply looking at a part others, with a tight connection due to sufficient internal tension in the material of the two parts is achieved.

Serves to complete the Oleinfüllstutzens 1 on its filling hole a cover 8, also made of plastic, which has a cover on the oil filler neck executed collar 9 is turned inside out and a tight seal due to its tension manufactures. The cover 8 is, in order to the usual measure, all lubrication points red to mark enough to do, executed in red plastic. The lid 8 can like the entire oil filler neck 1 can be provided from plastic without any processing and is therefore particularly cheap like this one.

The appropriate training is in particular on motor vehicles engine compartment open at the bottom and side access, such as B. in small vehicles or also sub-urban trucks and buses, advantageously applicable.
