<p>PROBLEM TO BE SOLVED: To prevent blocking of an air feed route and limiting of a feed of supply air due to icing of a moisture content in supply air by effecting cooling from the air exhaust route side, when an air feed route and an air exhaust route for compressed air are positioned adjacent to each other. SOLUTION: An air feed route 29 and an air exhaust route 45 are formed in a female type socket 11 adjacent to each other. A valve element 28 for closing an outlet from the deep side is positioned in the vicinity of the outlet of an air feed route 29 and a coil spring 34 for energizing the valve element 28 toward the outlet side is situated in the air feed route 29. A heat insulation tube 32 for interrupting heat conduction to the valve element 28 is located between the air feed route 29 and the air exhaust route 45.</p> |
