Abstract
A fluid management system for an automotive propulsion system is provided. The fluid management system includes a conduit system configured to deliver hydraulic fluid. A housing defining a sump is configured to collect a volume of hydraulic fluid and gaseous fluid. At least one intake valve is disposed in selective fluid communication with the conduit system and the sump. The intake valve(s) is/are configured to allow the passage of the hydraulic fluid from the sump to the conduit system and to substantially prevent the passage of the gaseous fluid from the sump to the conduit system. Thus, hydraulic fluid that is substantially free of air is provided to hydraulic system components downstream of the intake valve(s).
