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 water drain assembly for draining water from a filter assembly comprises a conduit, a water canister, and a venturi. The conduit fluidly connects a bottom portion of the filter assembly to a bottom portion of the water canister. The venturi comprises a first venturi inlet that allows fluid to flow from the fuel tank and into the venturi, a second venturi inlet that allows fluid to flow from the water canister and into the venturi, and a venturi outlet that allows fluid to flow from the venturi and into the filter assembly. The second venturi may comprise a capillary.

Abstract: Various arrangements of a turbine for a rotating coalescer element of a crankcase ventilation system for an internal combustion engine are described. In some arrangements, the turbine is an impulse turbine, which is also known as a pelton turbine or a turgo turbine. The turbine is used to convert hydraulic power from a stream of pressurized fluid to mechanical power that is used to drive the rotating element. The turbine includes a non-wetting surface (e.g., an oleophobic or hydrophobic surface) that repels the pressurized fluid. The non-wetting surface may be achieved through plasma coating, fluoropolymer coating, micro-topography features, and the like. The non-wetting surface increases the power transmission efficiency from the stream of pressurized fluid to the turbine, thereby increasing the rotational speed of the rotating element compared to wettable surfaced turbines, which in turn increases the efficiency of the rotating element.

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: Systems and methods for detecting a missing coalescing element in a CV system are described. In some arrangements, the described systems and methods prevent the assembly and/or re-assembly of the CV system without an appropriate coalescing element positioned within the CV system housing (e.g., during a coalescing element service operation). In some arrangements, the coalescing element depresses a spring-loaded component of a shaft that provides flow of bypass gases to the CV system. If the spring-loaded component is not depressed, significant restriction is introduced to the CV system, and an on-board-diagnostic system may detect high-crankcase pressure through existing crankcase pressure sensors and de-rate the internal combustion engine. In other arrangements, a spring-loaded mechanism within the shaft prevents a housing cover (e.g., a lid to the housing of the CV system) from being repositioned when a coalescing element is not installed within the housing.

Abstract: Fuel filtration systems having an automatic drain assembly for water that accumulates in the filter housing are described. The filtration system includes a filter media that is configured to remove particulate matter and dispersed water contained within the fuel. The water is drained to a drain reservoir within the filter housing where the water collects. When the water reaches a threshold level, a controller initiates a warning to the engine operator, such as a dashboard light, that instructs the operator to shut the engine off. When the engine is shut off, the collected water is drained through a valve of the automatic drain assembly. In some arrangements, the automatic drain assembly can be retrofitted to existing fuel filtration systems thereby reducing the cost of fitting the automatic drain assembly to existing internal combustion engines.

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 separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine positioned within the housing and positioned so as to be contacted by the fluid expelled from the jet. The fluid causes the turbine to rotate about a center rotational axis within the housing. The turbine comprises a first axial end, a second axial end, and a plurality of vanes extending axially relative to the center rotational axis from the first axial end to the second axial end. The plurality of vanes defines axially-extending channels between each of the plurality of vanes. The first axial end is axially open such that fluid can flow unblocked axially through the first axial end and into the channels. The jet is positioned such that at least a portion of the fluid enters into the turbine through the first axial end.

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: A filter assembly includes a drain port comprising a top portion and at least one surface modification along the top portion. The drain port defines an aperture therein and is alignable with an outlet port. The outlet port includes a seal member that is attachable to an end portion of the outlet port. A portion of the aperture of the drain port is sealable to the seal member when the drain port and the outlet port are aligned such that the at least one surface modification of the drain port does not abut the seal member of the outlet port, thereby creating a sealed connection between the drain port and the outlet port.
