Anchor seal assembly

Patent ·
OSTI ID:5358218
An anchor seal assembly is shown of the type used to anchor tubing within the bore of a surrounding conduit to provide a seal between the conduit bore and the tubing. A threaded connector circumscribes a portion of the exterior of the tubing. The threaded connector has external threads for matingly engaging a threaded interior surface within the bore of the surrounding conduit. The threaded connector is slidingly received within a recess provided within the exterior surface of the tubing. The tubing recess has a shoulder area at one end thereof for contacting an end of the threaded connector and has a ramp area at the opposite end for contacting the opposite end of the connector. Movement of the tubing in one direction relative to the conduit bore causes the threaded connector to contact the tubing recess shoulder area thereby causing the connector to ratchet into engagement with the threaded interior surface within the bore of the surrounding conduit. Movement of the tubing in the opposite direction relative to the conduit bore causes the threaded connector to contact the tubing recess ramp area forcing the threaded connector radially outwardly into tighter engagement with the conduit threaded interior to further anchor the seal assembly within the conduit.
