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 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: A connection between a fluid filter and a head is described that permits quick connection/disconnection between the two without requiring disconnection of fluid lines from the head. The head includes a lock to connect inlet and outlet fluid lines to a fluid filter using a non-threaded attachment method. The lock that retains the head to the fluid filter is flexible to allow for connection and disconnection. The head has fluid inlet and outlet ports to which fluid lines attach to flow unfiltered fluid into and filtered fluid out of the fluid filter when the head is connected to the fluid filter. The head closes the fluid filter, which has a protrusion with adjacent passageways that guide and separate unfiltered from filtered fluid.
