Abstract
A dual air-oil separator which separates two air-oil mixtures of differing proportions in a single unit having first and second chambers for the separate mixtures. The two chambers are separated by a perforated partition wall. The air-oil mixture, high in air is separated as it passes from the first chamber through the perforated wall and into the second chamber. The second chamber directly receives the air-oil mixture, low in air, for separation and combination in its sump with the oil from the first chamber.

A duplex air-oil separator for separating two air-oil mixtures of differing proportions from and engine crankcase vent and a turbo-charger oil drain comprising:
- a housing;
- a first perforated partition wall located within the housing defining first and second separator chambers each having upper portions and sumps at the bottom thereof;
- a first conduit means from the engine crankcase vent communicating with the first separator chamber to transmit the air-oil mixtures high in air to the first chamber for separation, a second conduit means from the turbo-charger oil drain communicating with the second separator chamber to transmit air-oil mixtures low in air to the second chamber for separation, an exhaust vent conduit communicating the upper portion of the second chamber to atmosphere, and a sump drain conduit connected to the sump area of the second chamber.
