An oil seal for a locking differential mechanism. The seal assembly includes a generally flat plate with a first generally circular oil seal adjacent an outer margin of the flat plate, a circular inner margin defining an opening in the flat plate with a second oil seal surrounding the inner margin, an oil outlet opening lying in an otherwise imperforate area between the first and second margins, and a cover for the flat plate with the cover and plate defining between them a passage for oil extending from a point radially outside the first seal to at least a point adjacent the oil outlet. The seal takes in a supply of oil from the differential sump and supplies it through the oil outlet to a multi-plate clutch which is activated only when the two axles undergo rotation relative to each other and thereby actuate a Gerotor type oil pump.

[ What is claimed is:] [1.] A plenum seal assembly, comprising, in combination, a generally flat plate assembly with radially inner and outer margins and including a first oil seal body adjacent said outer margin thereof, and a second oil seal assembly adjacent said inner margin thereof, an oil outlet opening in said plate lying between said inner and outer margins, said plate including a portion extending radially outwardly beyond said outer margin, and a cover for said plate, said cover extending generally from a locus radially outwardly of said outer diameter seal body to a point generally adjacent said oil outlet opening and cooperating with said plate to define an oil passage and an oil inlet opening, said cover being sealed in substantially fluid-tight relation to said flat plate except for said inlet and outlet openings, thereby providing an assembly for picking up oil from a sump lying outside said outer diameter margin and supplying said oil to a mechanism having an oil inlet lying radially between said seal bodies.
