Patent number: 7117891Abstract: The invention is directed to a pressure bleed device for a hydraulic coupling which includes a male component that comprises a body, a flow passage which extends generally axially through the body, a valve seat which is formed proximate one end of the flow passage, and a valve element which is biased into sealing engagement with the valve seat to thereby close the flow passage. The pressure bleed device includes a bleed passage which extends through the body and communicates with the flow passage, and a valve for selectively opening the bleed passage when an internal pressure within the flow passage is greater than an external pressure outside the body. Thus, when the flow passage is closed, excess internal pressure within the flow passage is vented outside the body through the bleed passage.Type: GrantFiled: September 9, 2004Date of Patent: October 10, 2006Assignee: FMC Kongsberg Subsea ASInventors: Heyn Halfdan Magnus, Petter Støvset
