Abstract: A filter element for filtering a fluid that comprises a pleated filter media and a support structure. The pleated filter media comprises pleats that define an upstream gap along an upstream surface of the pleated filter media and a downstream gap along a downstream surface of the pleated filter media. The support structure extends along the downstream surface of the pleated filter media and supports the pleats. The support structure is folded into two layers comprising a first layer and a second layer within the downstream gap. The first layer inner surface and the second layer inner surface are positioned adjacent to each other within the downstream gap. The support structure comprises at least one spacer that increases a distance between the first layer outer surface and the second layer outer surface such that the differential pressure drop through portion of the support structure that is within the downstream gap is decreased.

Abstract: Inertial particle separators having an axially translating or a deformable poppet component are described. The poppet component axially translates to accommodate a wide range of flowrates through the inertial particle separator. In some arrangements, the poppet component is biased by a spring towards a closed or restricted position. The variable flowrate and constriction provided by the poppet maintains a substantially constant pressure drop and separation efficiency during operation across a wide range of flowrates through the separators.

Abstract: A no filter no run bidirectional pin element is disclosed. A shell housing is removably coupled to a filtration housing, a removable no filter no run attachment, and a filter element. The filter element comprises a filtration media and a bidirectional pin element. The bidirectional pin element comprises a center tube formed as a single piece with a bidirectional pin. The installation of the filter element and the shell housing into the filtration system results in the bidirectional pin entering a pin aperture of the removable no filter no run attachment and the bidirectional pin preventing the operative engagement of a blocking element with a divider inside the no filter no run attachment.

Abstract: Various embodiments relate to an air intake duct. The duct includes louvers forming an air inlet to a housing. Each louver includes an inlet section and an angled section, the angled section inclined with respect to the inlet section. The duct includes the housing positioned downstream of the louvers in an air flow direction. The housing includes a drain configured to permit separated water from an intake air passing through the louvers and into the housing to be drained from the housing. The duct includes an inner inlet duct that provides the intake air to a component. The inner inlet duct extends into the housing and positioned downstream of the louvers in the air flow direction. The inlet duct extends above the drain by a distance thereby forming a well in the housing between a top of the inner inlet duct and the drain.

Abstract: A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

Abstract: Filter housings that have housing wall surface irregularities are described. The surface irregularities are positioned on the inner walls of the housings and/or axial ends of the housing walls. The surface irregularities may be, for example, grooves, ribs, bumps, and the like. The surface irregularities provide an engine integrity protection (EIP) feature by preventing non-approved replacement filter elements from forming seals against alternative sealing surfaces of the housing wall inner surfaces or axial ends.

Abstract: Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a contact seal to seal a gap between a static side of a housing and a rotating coalescer inlet. The rotating coalescer may be driven mechanically, electrically, hydraulically, or the like. The contact seal can be formed via a soft solid or a liquid film created by oil. Accordingly, the contact seal is a hydrodynamic soft seal. The contact seal prevents the blowby gases from bypassing the filter element of the rotating coalescer. At the same time, the contact seal may be broken during positive blowby gas recirculation circumstances because the contact seal is a hydrodynamic soft seal.

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.
