Abstract: A system for providing air to an internal combustion engine comprises a crankcase ventilation unit that receives unrefined blowby gas from a crankcase, separates oil from the unrefined blowby gas, and discharges refined blowby gas. A conduit delivers the refined blowby gas to an air cleaner housing. The air cleaner housing comprises a first chamber that receives intake air through a first port, a second chamber that receives intake air from the first chamber and refined blowby gas from the conduit through a second port, and a third chamber that receives a mixture of intake air and refined blowby gas from the second chamber and discharges the mixture through a third port. A primary filter element filters the intake air as it passes from the first chamber to the second chamber. A secondary filter element filters the mixture as it passes from the second chamber to the third chamber.

Abstract: A mounting assembly is described that has an interface designed to increase the stress margin of at least the module side of the assembly, for example in a liquid filtration module, and to increase ease of assembling its mounting components. The interface reduces the failure of the mounting assembly at least on the module side, so that if failure of the mounting assembly occurs, such an occurrence is less likely to be at the interface and on the module side, thereby reducing the need to replace more complex and expensive components that may be on the module side. Generally, the mounting assembly includes a mounting interface and a mounting bracket connectable to the mounting interface. A retention component is configured to maintain connection of the mounting interface to the mounting bracket.

Abstract: A filter cartridge is provided. The filter cartridge includes a first end plate connected to a first end of a filter media, a second end plate connected to a second end of the filter media and a centering device. The centering device is located towards the second end of the filter media for aligning a pin of the first end plate into a hole of a filter housing. The centering device also includes first ribs at first opposing ends of the centering device and second ribs at second opposing ends of the centering device, the first and second ribs protruding inwardly toward the center of a centering device hole. The length of the first ribs towards the center of the centering device hole and the length of the second ribs towards the center of the centering device hole are designed to align with a cross-sectional shape of the standpipe hole.

Abstract: In an inside-out flow filter, a transition pressure recovery member is provided at the inlet and has structured contoured guide surfaces guiding fluid flow therealong into the hollow interior of an annular filter element to minimize transition pressure loss from the inlet to the hollow interior. The transition pressure recovery member includes transition flow deceleration surfaces gradually decelerating flow of fluid into the hollow interior and minimizing pressure drop.

Abstract: A gas-liquid rotating coalescer includes first and second sets of one or more detent surfaces on a rotary drive member and a driven annular rotating coalescing filter element which engagingly interact in interlocking mating keyed relation to effect rotation of the coalescing filter element by the rotary drive member. Designated operation of the coalescer requires that the coalescing filter element include the second set of detent surfaces. A coalescing filter element missing the second set of detent surfaces will not effect the noted designated operation.

Abstract: Improvements to “no filter, no run” fluid filtration systems are described. In one example, a filter includes a movable pin cage that has a first pre-installation position adjacent the bottom end plate and is temporarily connected thereto by a snap connection system, and a second position adjacent the upper end plate where it performs a valve interaction function. In another example, a filter includes non-centered valve pins that are rotatable relative to an upper end plate of the filter.

Abstract: An inertial separation air precleaner system includes a replaceable insert removably mounted to the precleaner and altering air flow velocity through the precleaner by changing flow area of the flowpath through the precleaner housing. The replaceable insert is replaceable with a different insert for the same precleaner housing, which different insert provides a different flow area through the precleaner housing, enabling a selectable precleaner efficiency vs. restriction trade-off as chosen by a user for a particular application, enabling tuning of precleaner performance by the user.
Abstract: A gas-liquid rotating separator has first and second sets of magnetically permeable members magnetically interacting with each other to effect rotation of a separator element. A nonauthorized replacement separator element missing the second set of magnetically permeable members will not effect designated operation, thus ensuring, at maintenance servicing, installation of an authorized replacement separator element.

Abstract: A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.
