Abstract: A pleated filter media comprises a plurality of pleats comprised of pleat segments extending in an axial direction between first and second axial ends and extending in a transverse direction that is perpendicular to the axial direction between first and second sets of pleat tips at least partially defined by first and second sets of bend lines. Axial flow channels are defined between the pleat segments in the lateral direction and the plurality of pleats has a width in the transverse direction that varies along the axial direction.

Abstract: The combination of a gas-pressure-driven pump jet nozzle or alternatively Coanda effect nozzle with an impactor nozzle(s) in an air-oil separator for separating oil from blow-by gasses from a crankcase of an internal combustion engine, or for separating liquid aerosol from gas, in general. Such combination enhances impaction efficiency and enables operation at higher pressure differentials (or pressure drop) (“dP”) without causing excessive backpressure in the air-oil separator.

Abstract: A gas-liquid separator comprises a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. An impactor nozzle structure is supported by the housing and situated downstream of the inlet. The impactor nozzle structure receives the gas-liquid stream and accelerates the gas-liquid stream through an orifice that extends through the impactor nozzle structure. An impaction surface is supported by the housing and situated downstream of the orifice. The impaction surface receives the accelerated gas-liquid stream and causes separation of liquid particles from the gas-liquid stream so as to produce the gas stream, and a baffle situated downstream of the impaction surface modifies a flow of the gas stream so as to reduce carryover of liquid particles in the gas stream. A shroud for an inertial impactor gas-liquid separator is disclosed. A method for separating liquid particles from a gas-liquid stream is disclosed.

Abstract: A gas-liquid separator has a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A nozzle structure in the housing has a plurality of nozzles that receive the gas-liquid stream and accelerate the gas-liquid stream therethrough to create a plurality of gas-liquid jets. An inertial collector in the housing causes a sharp directional change of the gas-liquid jets, causing separation of liquid particles from the gas-liquid stream to produce the gas stream. The inertial collector has a porous collection substrate. According to the present disclosure, at least one of the following three conditions is met: (a) the porous collection substrate comprises fibers of small diameter and has low packing density; (b) the porous collection substrate comprises oleophobic fibers; and (c) the nozzle structure and the inertial collector are configured to allow for full expansion of the plurality of gas-liquid jets.
