<P>PROBLEM TO BE SOLVED: To provide a fluid joint capable of attaining further pressure drop reduction by shortening a resistance-causing section of a member causing resistance in a flow path. <P>SOLUTION: The fluid joint includes, in a plug 1 and a socket 2: valves 41; springs 71 to bias the valves 41 so as to bring the valves 41 into pressure contact with valve seats 4, 10; and spring holders 61 to position and hold the springs 71. When the plug 1 is inserted into the socket 2, the valves 41 abut against each other and retreat, such that flow paths between the plug 1 and the socket 2 are connected to each other. Each of the valves 41 includes: a largest diameter portion 42 that abuts against an inner circumferential surface of the plug 1 or the socket 2 and positions the valve 41 in the axial direction thereof; and an inclined surface 43 reduced in diameter into a conic shape from the largest diameter portion 42 toward both sides in the axial direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
