Dry sump lubrication common drive for IC engine - has single common drive of scavenge and main lubrication pumps to assist compactness in dry sump layouts

摘要

A dry sump lubrication system for an internal combustion engine has a scavenge pump to pump drained oil from the sump tray into an oil reservoir (14). A main lubrication pump then supplies the lubricating circuits from this reservoir (14). The pumps are arranged such that they are driven from a single, common drive shaft (A). The use of meshing or vaned pumps to reduce the sump depth, and the location of a slim interconnecting shaft (18) in the crank case wall are also described. USE/ADVANTAGE - Dry sump lubrication of internal combustion engines. Compact arrangement of main and scavenge pumps driven from joint shaft.
