<p><P>PROBLEM TO BE SOLVED: To provide a combined system gradually adaptable to super high pressure. <P>SOLUTION: A valve element for each of low and high pressure couplers 1, 2 is arranged on a supply side A of a partition wall 11 in the state of being energized to a closing direction. To the valve element 12, a stem 13 is joined which passes through an opening portion and protrudes to a reception side B. The partition wall 11 has a cylinder portion 18 formed on the reception side B. A locking means 22 is provided near the end thereof. A movable sleeve 23 having an annular protruding portion 26 is provided inside the cylinder portion in the state of being energized to an unlocked position of the locking means 22. Low and high pressure plugs 3, 4 each have an annular protruding face 34 engageable with the annular protruding portion 26, a flange 33 for engaging with the end of the cylinder portion 18, and an engaging portion engageable with the locking means 22. A distance a1 from the locking means 22 of the high pressure coupler to the end of the stem 13 is longer than a distance a2 from that of the low pressure coupler. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
