What distinguishes double lip oil seals from single lip oil seals?

The rim seal chamber of the single lip seal is open to the mainstream and has a rectangular cross-sectional area. Because the double lip seal has an upper seal lip, its rim seal cavity is about 20% smaller than that of the single lip seal.

Do lip seals have direction?
