| 摘要 |
The present invention relates to an improved hydraulic coupling which forms contact seals to fluidly connect a tapered port with a tube having a threaded connecting portion. The contact seals may be metal-to-metal seals, or alternatively may include a resin polymer element. The invention provides a fluid coupling for a tube which is transverse to the port, allowing for flow redirection in the coupling similar to the flow redirection in prior art "banjo" couplings. The body of the port includes a lip which deforms on the inner tapered surface of the fitting, and the fitting also includes an inner tapered surface on which a rim of the bolt contacts, thereby providing a contact seal at both potential leak points. The lipped port may also be provided by a collar disposed between the port and the fitting. Optionally, o-rings may be added to provide additional seals. The present invention may be designed not to seal without the application of tool generated torques.
