Definitions
- the invention has for its object to show the design and arrangement of a lubricating oil channel that can be represented and varied in a simple and cost-effective manner, can be installed in a space-saving manner in the crankcase, is easily accessible and can be dismantled together with spray nozzles, and in particular it can also be ensured that impurities of the lubricating oil duct due to chips or other processing residues.
- Fig. 1 is a fragmentary cross-sectional view of the
- the outline of the connecting rod violin is shown in broken lines.
- the arrangement of the lubricating oil channel just below the upper boundary wall 13 allows a compact construction of the engine, in which there is only a narrow space between the upper boundary wall 1 of the crankcase 5 and the engine parts rotating with the crankshaft.
- the through holes in the transverse walls cannot be too close to the critical transition area between the transverse wall and the upper boundary wall of the crankcase. Due to the design of the lubricating oil channel, the through bores in the transverse walls can be made deeper than the riser tubes 10.
