A filter assembly for fluid filtration having a push-activated lock and
release mechanism. The filter housing has a sump for enclosing the filter
media, a filter head, and at least one standoff protruding outwards for
use in securing the filter head to a filter manifold. The filter manifold
supports the filter housing with a filter locator. A filter guide having
a rotator actuating mechanism secures and holds the filter head in place
when the filter head is axially inserted. The rotator actuating mechanism
has tabs and slots that rotate upon a transverse axial force from the
standoff and from tabs on an internal shutoff. The internal shutoff has
an inlet extension and an outlet extension with apertures for fluid
ingress and egress. The internal shutoff tabs slidably contact and align
the rotator actuating mechanism to secure and remove the filter head.
