<p>PURPOSE: To prevent liquid leak from a coupling by fitting and detaching a coupling by pressing, rotating, and rotational drawing out, and separating from a seat or seating mutual mating means (valve bodies) by a cam means at rotating. CONSTITUTION: When one embodiment 13 of a coupling 11 is pressed against the other embodiment 15 so as to insert a pin 87 into the groove 93 of a skirt part 91, one projection 55 is fitted into the other socket 57 while keeping both mating means 43, 45 in the closed state. Next when the embodiment 13 is rotationally moved so as to put the pin 87 in a groove 89, the projection 55 is moved upward in a socket 57 by a cam means 53, both the maiting bodies 43, 45 respectively open opening parts 35, 37 against springs, and liquid is led from an inlet 23 to an outlet 25. When the coupling 11 is separated, rotational drawing out opposit to the above-stated is executed. In this way, at fitting and detaching the coupling, liquid can be prevented from leaking.</p> |
