This type of oil-sealing piece is already known (Special Publication in 1983).
-147850), and has been completely proven. However, since oil seals of this type traditionally form a closed frame, the replacement of these oil seals requires that the new oil seal be assembled in order to
This is difficult in that the main parts of the drive block must be disassembled and the drive block must be removed from the tank. Another drawback is
Different oil sealing pieces are required for internal combustion engines with different dimensions in the longitudinal direction of the crankshaft, and therefore for example 6-cylinder engines and 4-cylinder engines, for example, by appropriately shortening the same oil sealing piece for different numbers of cylinders. It also lies in the fact that it cannot be used in internal combustion engines.

The object of the present invention is to improve the oil sealing piece mentioned at the outset by relatively simple means so that a significant reduction in assembly costs is achieved and its use in internal combustion engines with different longitudinal dimensions of the crankshaft is achieved. The goal is to make it possible.

In order to solve this problem, according to the invention, the oil-tight piece is separated at at least one point,
The ends of the sealing pieces that abut one another can be connected by means of a thin elastic strip that contacts the bellows inner surface of the oil-tight sealing piece and the side surface of the lug adjoining this bellows inner surface.

According to the invention, the oil-sealing piece does not form a closed frame but is separated at at least one point, so that a damaged sealing piece can be easily replaced by a new oil-sealing piece. In other words, this new oil seal can be manufactured without dismantling the internal combustion engine by running the ends of the oil seal along the grooves of the reservoir and drive block, and then pushing the protrusion of the oil seal into the groove. Because you will get it. However, despite the separation of the oil-sealing piece, at the point where the ends of the sealing piece meet,
A complete seal is ensured by the strip. This is because when the oil sealing piece is pushed into the groove, the area of its bellows is in close contact with the joint strip, and the thin seaming strip, due to its elasticity, absorbs all the sealing movement of the bellows of the oil sealing piece. This is because there is no risk of the vibration of the drive device block being transmitted to the tank at the abutting point. Since the side surface of the protrusion adjoining the outer surface of the bellows is exposed without contacting the joint strip, this side surface of the oil-sealing piece that is pushed in can be pressed against the corresponding groove wall and act as a seal.

In a further development of the invention, the sleeve has edge lugs bent at an acute angle over the projecting side facing towards the groove bottom, the width of these edge lugs exceeding the groove width. These edge tabs act in a reverse hook-like manner within the groove and thus reliably prevent the sleeve from becoming unintentionally loosened within the groove. When the tabs reach these edge tabs, a snap-fit connection is created between the tabs and the sleeve. This is because the edge tab, which is bent at an acute angle, partially engages onto the tab.
