Abstract

For the distribution of lubricating oil, a duct is arranged in the crankcase 13 of a piston-operated internal-combustion engine and extends through several transverse walls 11, 12. The sections of the duct between two transverse walls 11, 12 are composed of an insert pipe 23 and of a socket pipe 24 which are constructed to be axially slidable and clampable with respect to one another. The free ends of the insert pipe 23 and of the socket pipe 24, in a sealed manner, extend in the bored transverse-wall passages 14, 15 of the duct. The arrangement results in a simplified tooling of the crankcase 13 in the area of the duct.
