Abstract:
A full-flow failsafe, comprising:a filter element for filtering entrained particles from a flowing fluid stream; a shell having apertures at each end thereof for enabling said fluid stream to flow therethrough, a first one of said apertures being coupled to said filter element; a sealing plug movably positioned within said shell, said sealing plug being oriented in a first position during normal operation of said filter element to permit fluid flow through said shell, and being moved by increased fluid velocity to a second position wherein said sealing plug forms a sealing contact with a second one of said apertures, upon failure or breakage of said filter element; and at least one locking mechanism supporting said sealing plug in said first position, and being moved to a locking position for securing said sealing plug in said second position in response to said movement of said sealing plug.
