Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

Abstract: A liquid filter suitable for motor vehicles which includes a filter head (11), a vessel (12) and a filter element (16) disposed within the vessel (12) sealingly separating an inlet (14) from an outlet (15) such that liquid from the inlet must flow through the filter element to reach the outlet. The filter element (16) has guide projections (27, 28) positioning the filter element (16) within the vessel (12). Prior to installation, the filter element (16) is preassembled into the vessel (12) and fixed in position by pushing the filter element (16) into an element guide (29), after which the preassembly is screwed onto the filter head (11). When the vessel (12) is unscrewed from the filter head (11), the filter element (16) slides out of the element guide (29) and moves axially upwardly to free a volume V. Liquid flowing into the vessel (12) from the higher regions of the liquid filter (10) can flow into this volume, thus enabling drip-free replacement of the filter element.
