US Patent:

20140059985, Mar 6, 2014
Filed:

Aug 27, 2013
Appl. No.:

14/010730
Inventors:

Benjamin L. Scheckel - Stoughton WI, US
Ashwin K. Koleshwar - Stoughton WI, US
Lee A. Peck - Stoughton WI, US
Saru Dawar - McFarland WI, US
Assignee:

CUMMINS FILTRATION IP, INC. - Columbus IN
International Classification:

B01D 45/16
US Classification:

554594
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.

US Patent:

20160290194, Oct 6, 2016
Filed:

Nov 17, 2014
Appl. No.:

15/036729
Inventors:

- Columbus IN, US
Brian W.. Schwamdt - Fort Atkinson WI, US
Arun P. Janakiraman - Stoughton WI, US
Ashwin K. Koleshwar - Stoughton WI, US
Assignee:

Cummins Filtration IP, Inc. - Columbus IN
International Classification:

F01M 13/04
F01M 13/02
Abstract:

A crankcase ventilation system having a crankcase ventilation filter and a filter drain. The crankcase ventilation filter vents blow-by gases from a crankcase and separates oil from the blow-by gases. The crankcase ventilation filter drain collects oil separated by the crankcase ventilation filter and returns the separated oil to the crankcase or another component of the engine. A nozzle is coupled to a pressurized oil supply and directs an oil jet into a mixing bore of the system, which draws the oil back into recirculation. A valve is coupled to the filter drain and is configured to prevent collected oil from reentering the crankcase ventilation filter through an opening that connects the filter drain to the filter.
