Abstract
A hydraulic fuse closes flow of hydraulic fluid in a hydraulic line upon loss of downstream fluid pressure. The hydraulic fuse includes a housing having an upstream opening and a downstream opening and a poppet slidably mounted within the housing for opening and closing fluid flow between the upstream and downstream openings. A spool is slidably mounted within the poppet for opening and closing fluid flow between first and second ends of the poppet. The spool includes a head which is positioned within the poppet and a rod which extends outwardly from the second end of the poppet and into the housing. When downstream pressure is lost, differential pressure acting on the first and second ends of the poppet will move the poppet to close fluid flow.
