<p>PROBLEM TO BE SOLVED: To provide a quick disconnect coupling capable of separating a female component from a male component without causing damage of a connecting line and leakage of hydraulic fluid. SOLUTION: This flat quick disconnect coupling includes the female component 1 and the male component 20, cylindrical members disposed radially outside the female component 1 are connected to the front part of a cylindrical sleeve 25, and an opposite side end of the cylindrical sleeve 25 is connected to an end connecting piece 26 connected to a collector of the hydraulic fluid. A valve body 34 having a valve pin 38 is disposed axially movably in a chamber partitioned by the cylindrical sleeve 25, the valve body 34 is fixed to a second cylindrical member 22, the second cylindrical member 22 extends longitudinally, and a circumferential groove for receiving a constraint ball is finished in a first cylindrical member 21 disposed at its end.</p> |
