Abstract: The apparatus includes a swirl vanes device for reducing the velocity of exhaust fumes fed into an enclosed container with the accompanying direction and volume changes enhancing the separation of the exhaust into gas, liquid, and solid components. Solids and liquids collect in the container and gas passes out through a demister filter. With engines having a pressurized crankcase exhaust and an air box outlet, an eductor assembly employing a spring-biased check valve is used to control the entrance of crankcase exhaust into an inlet chamber having a low pressure created by the volume expansion of inlet air box exhaust. A liquid overflow system has a floatable ball valve to remove liquid from the container under conditions of high liquid levels. An inlet and outlet manifold houses a spool valve for the selective control and isolation of the inlet and outlet openings of the container so that the container may be pressurized to remove the liquid collected therein.

Abstract: The apparatus separates exhaust fumes of an internal combustion engine into gas, liquid, and solids and comprises a container having an internal wall for substantially reducing the velocity of fumes fed into the container and allows the liquid and solids to collect in the bottom thereof with the fumes then passing through a demister filter to further separate same. A liquid level sensor connects to the container and senses when a maximum level is reached. The sensor may be of a float type and also can control a spring loaded valve in the fumes inlet passageway and/or a gauge connected by vertically spaced passageways through the side of the container, the latter gauge also could include an audible or visible alarm. A valved outlet is attached to the container for forcing the collected liquid in the container therethrough by the pressure of the incoming fumes when a plate covers the gas outlet above the filter.
