Valved quick-disconnect coupling

Abstract

Abstract THE SPECIFICATION AND DRAWINGS DISCLOSE A QUICK DISCONNECT TUBE COUPLING WHICH INCLUDES A FEMALE BODY MEMBER WITH AN AXIALLY EXTENDING BORE DEFINING A FLOW PASSAGE AND AN INTERNAL VALVE CHAMBER. A RESILIENT SLEEVE MEMBER IS POSITIONED WITHIN THE CHAMBER AND FORMS AN ANNULAR VALVE SEAT. A MALE BODY MEMBER IS ASSOCIATED WITH THE FEMALE BODY MEMBER AND INCLUDES A CYLINDRICAL STEM PORTION OF REDUCED DIAMETER AND A FLOW PASSAGE EXTENDING AXIALLY THROUGH THE STEM. THE DIAMETER OF THE STEM IS SIZED SO AS TO BE CLOSELY RECEIVED WITHIN THE BORE OF THE FEMALE BODY PORTION. POSITIONED WITHIN THE VALVE CHAMBER AND BIASED TOWARD THE SEAT AND THE STEM IS A PLUG VALVE MEMBER OF STEPPED DIAMETER WITH A REDUCED DIAMETER PORTION THAT EXTENDS THROUGH THE VALVE SEAT. THE DIAMETER OF THE PLUG''S REDUCED DIAMETER PORTION IS SUBSTANTIALLY LESS THAN THE DIAMETER OF THE VALVE SEAT AND THE DIAMETER OF THE END OF THE STEM. THE END OF THE STEM IS PROVIDED WITH FLOW PASSAGE OPENINGS WHICH ARE LOCATED RADIALLY OUTWARD AT A DISSTANCE GREATER THAN THE MAXIMUM DIAMETER OF THE REDUCED DIAMETER END PORTION OF THE PLUG MEMBER.
