Abstract:
An oil filtration system includes an oil chamber inlet. Also included is a first screen defining a first chamber volume that receives an oil flow from the oil chamber inlet, the first screen having a first mesh coarseness. Further included is a second screen surrounding the first screen to define a second chamber volume surrounding the first chamber volume, the second screen having a second mesh coarseness that is greater than the first mesh coarseness. Yet further included is at least one exit nozzle having an exit cross-sectional area that is greater than or equal to a cross-sectional area of apertures of the second screen. Also included is a bypass valve disposed in a first position during a first pressure condition within the first chamber volume and in a second position during a second pressure condition within the first chamber volume.
