| 20080276580 | Oil Mist Removal Device with Oil Fill - An oil mist removal device, with oil fill, is provided for an internal combustion engine. A housing has first and second passages, and a separator therebetween. An oil fill port in the first passage is provided for adding oil to the engine. | 11-13-2008 |
| 20090025662 | Crankcase Ventilation System with Pumped Scavenged Oil - A crankcase ventilation system for an internal combustion engine has a jet pump suctioning scavenged separated oil from the oil outlet of an air/oil separator and pumping same to the crankcase. | 01-29-2009 |
| 20090050121 | Two Stage Drainage Gas-Liquid Separator - A two stage drainage gas-liquid separator assembly includes an inertial gas-liquid impactor separator having one or more nozzles accelerating a gas-liquid stream therethrough, and an inertial impactor in the path of the accelerated gas-liquid stream and causing liquid particle separation from the gas-liquid stream, and further includes a coalescer filter downstream of the inertial gas-liquid impactor separator and effecting further liquid particle separation, and coalescing separated liquid particles. | 02-26-2009 |
| 20090090669 | DRIPLESS FILTER ASSEMBLY AND METHOD FOR SERVICING A FILTRATION APPARATUS WITH THE SAME - A fluid filter assembly of a filtration system is described. The filter assembly described includes a cover member and a filter cartridge having at least one filter element and a plate member. The plate member includes a seal surface on one side facing the cover member, and a seal surface on another side facing away from the cover member. The seal surface facing the cover member is configured to seal with the cover member, and the seal surface facing away from the cover member configured to seal with another component of the filtration system. The assembly provides a structure that can retain a seal between sealing surfaces of the cover and the filter cartridge, at least while the fluid filter assembly is being serviced, so as to at least minimize fluid dripping and leakage. | 04-09-2009 |
| 20090193972 | Separator with Transfer Tube Drainage - A dual stage coalescer includes a separator in a separator chamber separating gas and liquid by inertial impaction, and a coalescer filter element in a coalescer chamber separating gas and liquid by coalescence. A transfer tube extends between the separator chamber and a downstream subchamber in the coalescer chamber at the downstream face of the coalescer filter element, and supplies pre-separated liquid from the separator chamber through the transfer tube to the noted downstream subchamber as driven by pressure differential between the separator chamber and the downstream subchamber, to eliminate a dedicated housing drain outlet from the separator chamber. The coalescer may provide a crankcase ventilation filter for an internal combustion engine having blowby gas containing an air-oil mixture. | 08-06-2009 |
| 20100024366 | Gas-Liquid Separator with Dual Flow Impaction and Coalescence - A gas-liquid separator assembly has dual flow first and second split partial paths. The first path is an impaction separation path effecting liquid particle separation from a gas-liquid stream by inertial impaction. The second path is a coalescence-separation path effecting liquid particle separation from the gas-liquid stream by coalescence. | 02-04-2010 |
| 20100043734 | Crankcase Ventilation System with Engine Driven Pumped Scavenged Oil - A crankcase ventilation system for an internal combustion engine has an engine driven pump pumping scavenged separated oil from the oil outlet of an air-oil separator to the crankcase, preferably using engine generated pulsating oscillatory positive and negative relative pressure pulses. | 02-25-2010 |
| 20100101425 | Inertial Gas-Liquid Separator with Axially Variable Orifice Area - An inertial gas-liquid separator removes liquid particles from a gas-liquid stream and has a variable orifice area variable along an axial direction and dependent upon axial movement of a plunger relative to a housing sleeve. | 04-29-2010 |
| 20100107883 | Multistage Variable Impactor - An inertial gas-liquid separator and method is provided, including variable orifice jet nozzle structure having a variable orifice area dependent upon axial movement of a plunger relative to a housing sleeve, and in another embodiment having first and second flow branches, with the first flow branch being continuously open, and the second flow branch having a variable flow controller controlling flow therethrough. | 05-06-2010 |
| 20100175642 | Crankcase Ventilation System with Pumped Scavenged Oil - A crankcase ventilation system for an internal combustion engine has a jet pump suctioning scavenged separated oil from the oil outlet of an air/oil separator and pumping same to the crankcase. | 07-15-2010 |
| 20100258493 | Filtration Sealing System - A filtration sealing system is provided for sealing a filter element in a housing at a mating interface therebetween. The sealing system includes a keyed interface. A replacement filter element is provided for such filtration sealing system, with the replacement filter element including a keyed interface. | 10-14-2010 |
