Appl. No.:

US Classification:

Abstract:

A quick-disconnect, the nipple portion of which has a pressure relief path and a coupler portion of which has a safety lock. The nipple portion is provided with a spring-loaded sleeve which covers the relief flow path when not engaged. The sleeve is hand driven against the spring load to expose the flow relief passage. Any pressure in the quick-disconnect is then discharged to atmosphere. The coupler portion incorporates a piston that is pressure activated to block the motion of a disconnecting sleeve. The piston is moved to the unlocked position by a wave spring when the pressure is removed. These features are packaged in a small volume for use in systems where space is limited. The quick-disconnect is designed and fabricated with materials that can withstand a proof pressure of 20,000 PSI. Such capabilities are especially useful in aircraft systems with a supply pressure of up to 5,000 PSI. The pressure relief assures the quick-disconnect can be relieved of any residual pressure up to 5,000 PSI before it is uncoupled and the lock assures that it can not be uncoupled without pressure relief.
