Abstract:

The present invention provides a fluid coupling that can prevent fluid leakage without fail and can reduce manufacturing costs and manufacturing time. A fluid coupling (1) is provided with the following: a socket body (12); a stationary valve (21); a guide (30) that is linked to the stationary valve (21) and is energized so that it is pressure bonded to the interior surface of the socket body (12); a socket (11) that has a spring (49) that energizes the guide (30); and a plug (51) that has a plug body (52), a moveable valve (61), a spring (68), and a valve holder (71) that supports the moveable valve (61) and a spring (62). The fluid coupling is such that when the plug (51) is inserted into the socket (11), the guide (30) retracts in resistance to the energizing force of the spring (49), and a fluid channel between the plug (51) and the socket (11) is connected, and wherein a coupling unit (35) is provided on the end of the guide (30) for coupling with the tip of the plug (51) and first sealing members (40, 41) are provided between the coupling unit (35) and the tip (55) of the plug (51).
