Patent ID: 8590733

Claim:
A filter housing comprising: a vessel portion; a lid being sealingly matable to said vessel portion; an arm secured to said lid and movably engaged with said vessel portion, said arm including a slot for receiving a pin that is selectively fixed with respect to said filter housing, said slot being substantially aligned with a longitudinal axis of said arm for a portion of its length, said arm including external threads; and a rotational member for having a threaded part including threads for engaging said threads on said arm, said rotational member rotatable with respect to said vessel portion and restrained from longitudinal movement with respect to said vessel portion, so that rotation of said rotational member relative to said arm causes longitudinal movement of said arm and separation of said lid from said vessel portion, whereby said pin riding in said slot restricts rotational movement of said arm with respect to said housing when said pin is fixed with respect to said vessel portion, said pin being insertable through said rotational member and through said slot, so that said rotational member may impart rotation of said arm with respect to said vessel portion.
