  • Filter assembly with a pressure actuated valve assembly that permits air flow into a rotary vessel
    Patent number: 10981094
    Abstract: A filter assembly has a housing with a housing inlet and a drain. A rotary vessel is rotatably mounted within the housing and has a rotary vessel inlet and a rotary vessel outlet. Fluid exiting the rotary vessel outlet exits the housing through the drain. A valve assembly moveable between a closed and an open configuration is provided. When closed, the valve assembly fluid-tightly seals rotary vessel inlet from housing inlet. When open, the rotary vessel inlet is in fluid communication with the housing inlet such that fluid flowing into the housing inlet passes into the rotary vessel inlet. The valve assembly is moveable from closed to open configuration when a pressure of fluid flowing into the housing inlet exceeds a threshold pressure. The filter assembly has a fluid passageway permitting air flow into the rotary vessel through the rotary vessel inlet when the valve assembly is closed.
