    摘要： An apparatus for reducing crankcase emissions generated by an engine is described. The apparatus generally includes a separator that removes particulate matter from the crankcase emissions and a treatment component that removes odor and gases from the crankcase emissions. The apparatus is configured where the treatment component is disposed downstream of the separator, the separator first removes particulate matter from the crankcase emissions and the treatment component then removes odor and certain gases from the crankcase emissions.

    摘要： A cleanable backflushable re-usable dual full-flow and bypass filter includes a full-flow filter element providing filtered primary flow therethrough, a bypass filter element providing filtered secondary flow therethrough, a bypass tube conducting flow therethrough from said bypass filter element to said full-flow filter element, a venturi creating a low pressure zone aiding secondary flow through the bypass tube to assist in pulling the secondary flow through the more restrictive bypass filter element, wherein fluid, whether main fluid flow in the filtering direction or backflushing cleansing fluid flow in the opposite direction, flowing from the bypass tube changes direction at the venturi. During a backflushing cleaning cycle, a backflush deflector at the outlet end of the bypass tube in the venturi creates the directional change by changing axial flow of cleansing fluid through the bypass tube to radial flow at the outlet end of the bypass tube in the venturi and prevents straight-through rectilinear flow of cleansing fluid from the bypass tube to the filter outlet. Jets are provided, jumping the cleansing fluid across a radial gap between the bypass tube and the venturi throat to a region outside of the venturi and within the hollow interior of the full-flow filter element, to disperse and backflush the full-flow filter element.
