Air-cooled oil sump with fins for receiving oil in a heat exchange relationship

摘要

A sump for internal combustion engines, having external fins for flow of cooling air thereover, the sump receiving hot oil returned from the engine and having internal passages in heat exchange relationship with the finned surface, the returned oil being pressurized within the sump and forced through the internal passages for efficient cooling before being again circulated through the engine. The sump is usable without modification on engines with the axis either vertical or horizontal or at any angle therebetween.
