Hydraulic safety hose with fluid removal conduit

Claim 1

A hydraulic safety hose comprising: a first flexible high pressure hose for transmitting hydraulic liquid under high pressure; a second flexible high pressure hose surrounding and substantially coextensive in length with said first hose, said first and second hoses defining an annular hydraulic liquid passageway therebetween and being sealed together at opposing ends thereof so as to fluidly terminate said annular passageway extending therebetween; a hydraulic fluid coupling secured to each of said opposing ends of said first hose; and conduit means extending outwardly from said first and second hoses and fluidly communicating with said annular passageway for draining hydraulic liquid from said annular passageway to a remote location in the event of rupture of said first hydraulic liquid pressure hose, said conduit means including a fluid detector and an electrically connected solenoid valve for detecting hydraulic liquid flow through said conduit means and actuating said valve upon detection thereof to prevent hydraulic liquid flow from said annular passageway, and said conduit means further including a manually actuated valve for closing said conduit means to fluid flow downstream from said solenoid valve.
