Abstract
The invention relates to the construction of a lubricating oil channel (12), by way of which lubricating oil is conducted to spray nozzles (2) for the cooling of the pistons of an internal combustion engine. The spray nozzles (2) are connected with spray nozzle holders (3) that are secured at cross walls (4) in the crankcase (5). Passages (7) formed-in into the spray nozzle holders (3) which adjoin through-bores (9) in the cross walls (4). Plug-in pipes (10) are arranged between the passages (7) of two mutually oppositely disposed spray nozzle holders (3) secured at different cross walls (4) which complete the lubricating oil channel. A simple and cost-favorably representable lubricating oil channel is indicated therewith. A particular advantage is that the components of the lubricating oil channel are finish-machined prior to the installation and thus contaminations by machining residues are controllable prior to the installation. The lubricating oil channel is adapted to be laid out space-savingly in the crankcase (5) and again disassemblable for servicing.
