Abstract: A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element, and in a toroidal vortex ring created in the annular space. The area and geometry of the helical path, the conical cavity, and the inner and outer tubes is optimized to provide efficient separation at varying gas flow rates and at varying liquid loads.

These particle exits are so located that they are in line with the transport direction of the particles by the secondary flows.

Abstract: A vortical-type separator for removing from the gas stream suspended particulates present in the gas stream has an internally generated scavenging gas flow and a pulse jet system for cleaning scavenging gas filter elements. The separator has two or more conduits that are coaxially positioned with an annular clearance at their ends. A gas swirl device creates a swirling motion, causing heavier particulates to be discharged out the annular clearance or ejection port into a scavenging gas plenum. A flow path is created between the scavenging gas plenum and the outlet of the separator, with the pressure differential between the outlet and the ejection port causing scavenging gas to flow to the outlet. A frame is mounted in the flow path over which a bag filter is secured. The dust-laden scavenging gas flows through the bag filter and out the outlet. A nozzle is positioned at the mouth of the bag filter for periodically discharging a pulse of clean gas into the bag filter reverse to the flow of the scavenging gas.

Abstract: An air introduction assembly for a vehicle engine located with respect to a roof mounted air deflecting member to perform an air cleaning or contaminant separating function. The air inlet is placed in a plane substantially parallel to the surface of the deflector over which air flows during vehicle movement and opens normally to the direction of the air flow. Air passing thereover which enters the inlet must be diverted in an arcuate path which causes contaminant particles to pass the inlet. The air inlet is partially defined by a forward peripheral edge portion offset outward from the surface of the air deflector so that a moving contaminant-laden layer of air immediately adjacent the deflector surface is excluded from entering into the inlet. Leading from the inlet is an air passage which tangentially introduces the air entering the inlet into a cylindrical separator chamber.

Also described is an embodiment including a pump having a rotor disposed in the filter housing such that the hydrocyclonicly flowing water also drives the pump.
