A cantilevered conduit connection including a connecting block circumscribing a conduit and mounting to a fluid component where an anti-cantilever fastener mounts to a back surface of the connecting block. The anti-cantilever fastener includes a cusp portion bent toward and in contact with the back surface and induces a positive bending moment across the back surface of the connecting block for urging the connecting block flat against the fluid component and for positioning the conduit squarely within the fluid component. A device for fastening the anti-cantilever fastener and connecting block to the fluid component is also provided.

Anti-cantilever fastener for a conduit connection

A pressure vessel including a mounting block for supporting and retaining an inlet and an outlet tube to the pressure vessel. The mounting block includes a valve that communicates with an interior of the vessel and fastens the mounting block to a top of the pressure vessel. The mounting block enables access to the interior of the housing for accessories such as the valve, a sight glass, or a pressure switch, and the accessories can be either permanently or removably attached to the pressure vessel at the top or sides thereof. The mounting block may accommodate more than one valve.

Tube-to-vessel connection using a fastening valve

An accumulator deflector connection is used in an accumulator including a deep drawn can connected to a puck having an inlet passage and an outlet passage. The outlet passage includes a counterbore having a cylindrical bushing received therein, the deflector has a cylindrical extension received within the passage of the cylindrical bushing and the outlet end of the outlet tube is received within the passage of the cylindrical extension of the deflector and the cylindrical bushing is crimped to create a mechanical lock. In an alternate embodiment, the outlet end of the outlet tube includes knurling thereon and is located in the passage of the cylindrical extension of the thermoplastic deflector and the thermoplastic deflector is melted into the knurling during the welding of the can to the puck. In a further alternate embodiment, the outlet end of the outlet passage includes a radial channel located at the crimp of the connection to create a stronger mechanical lock between the cylindrical bushing, the deflector and the outlet tube.
