Abstract
A ventilator for use with an internal combustion engine includes an oil sump located at the lower end of the vertically extending outlet tube of the ventilator, a check valve disposed at the bottom of the sump for allowing fluid to flow from the sump toward the pressure chamber of the ventilator, and an outlet port extending out through the side wall of the outlet tube. The outlet tube is in communication with an intake manifold via the outlet port. The oil sump cooperates with the check valve to prevent oil from flowing into the intake manifold through the outlet port.
