<p>A current invention provides a low pressure loss type fluid coupling having a valve holder which has a large effective opening area and never drops the strength thereof. In the fluid coupling for connecting the fluid passages of the plug and the socket, a valve, a valve holder and a spring disposed in a compressed state between the valve and the valve holder are accommodated inside each of a plug and a socket to be connected to each other liquid-tightly, and when the plug is inserted into the socket, the valve of the plug and the valve of the socket make contact with each other so that the valves are retracted resisting an urging force of the spring. This fluid coupling further includes conical members (32,82,51,65) which form a conical external shape along a line connecting the outside diameter portion of the valve and the outside diameter portion of the valve holder when the valve of the plug and the valve of the socket make contact with each other, so that the springs are compressed between the valve and the valve holder.</p> |
