ABSTRACT:
The filter assembly employs a closure portion having fluid inlet and outlet ports integral therewith enabling in-line use of the assembly. Associated with such closure is a spring biased valve handle, whereby rotation of the handle along a prescribed course of travel enables simultaneous closing of the inlet and outlet ports thusly permitting free movement of the filter assembly body from the closure. A vent is provided in the closure which acts to relieve internal pressure within the assembly thereby further enabling easy removal of the filter body.
