<p><P>PROBLEM TO BE SOLVED: To secure durability and to prevent fluid leakage during separation and low pressure in a coupler comprised by respectively attaching a poppet valve to a nose and a body. <P>SOLUTION: A poppet 14 is arranged in the nose 12 so it can be moved by a spring 18. In the poppet 14, an annular groove part 15 is formed on a protrusive part 14A, and a seal member 24 made of rubber is burned in the groove part 15. Sealing is carried out by contacting the seal member 24 to a protruding part 22. A poppet 34 is arranged in a recessed insertion part 50 of the body 32 so it can be moved by a spring 38, and a seal member 44 made of rubber is burned in a groove part 35 formed on a protrusive part 34A of the poppet 34. Sealing is carried out by contacting the seal member 44 to a protruding part 42. By this, detachment of the seal members 24 and 44 due to gouging and deterioration is prevented, and fluid leakage is prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
