Abstract
A filter assembly includes a slidable tubular member which in a first position provides for flow communication from an inlet passage through a filter element to a filter chamber outlet. Upon removal of the filter housing and filter element the tubular member is biased to a second position to effect a flow shut off between the inlet passage and the tubular member. The filter assembly may further include an outlet passage in flow communication with the inlet passage, and a valve seat is axially aligned with the tubular member and disposed between the inlet passage and outlet passage. A valve member on the end of the tubular member is engageable with the valve seat to preclude flow between the inlet passage and outlet passage when the tubular member is in the first position and providing for flow communication between the inlet passage and the filter chamber outlet.
