Abstract: A filter cartridge in accordance with the present disclosure has a longitudinal axis and comprises a housing, a filter element, and a collar. The housing has a generally cylindrical sidewall and defines an open first end, an axially opposite second end, and a flange projecting radially away from the axis at the first end. The filter element has a ring of filter media circumscribing the axis and extending between first and second end caps. The first end cap has a generally cylindrical wall extending axially between first and second peripheral rims. The wall defines first and second seal glands adjacent the first and second rims which receive first and second seal members, respectively. A ledge projects radially outwardly from the cylindrical wall. The collar has an annular sidewall having a shoulder projecting from an inner surface. The ledge and the shoulder radially overlap and retain the flange therebetween.

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.

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: A draw latch retainer is used to secure a filter cartridge to a filter head. A cam actuated retainer extends from the head to engage a keeper in the top of the cartridge. Rotation of the cam draws the retainer and cartridge axially toward the head into an installed position. The retainer extends through an aperture in the upper portion of the cartridge to apply a retention force against the bottom side of the keeper. The keeper and upper portion of the cartridge supporting the keeper are configured to transmit the retaining force laterally across the top of the cartridge. A pair of axial conduits project from the cartridge and mount O-ring seals for implementing an axial sealing interface with passages in the head.
