<p><P>PROBLEM TO BE SOLVED: To simplify a valve mechanism built in a fluid coupling and reduce a load during connection. <P>SOLUTION: In a socket body 31 of a socket coupling 30, a bypass flow path 36 is formed for communicating a supply flow path 32 with a supply flow path 34. In a valve chest 70 where the bypass flow path 36 intersects the supply flow path 34, the valve mechanism 80 is provided for closing one of the supply flow path 34 and the bypass flow path 36. The valve mechanism 80 has a spherical valve element 82 turnably supported. Joint members 130, 150 mounted in screw holes 35b of the supply flow paths 32, 34 have valve elements 134, 135. The valve elements 134, 135 are separated from a valve seat member 136 and opened with a plug coupling 40 inserted into the joint members 130, 150. Besides, the valve element 135 has a thrust portion 135b whose front end thrusts the spherical valve element 82. Thus, the spherical valve element 82 is turned counterclockwise around a shaft 88 and separated from a valve seat 34a to close the bypass flow path 36. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
