Abstract

A coupling member 21 has a tubular member 70, 80 with a fluid passage 72, an 5 annular valve seat 102 provided on the tubular member, a valve member 76 that engages or disengages from the valve seat, and a valve support member 74 that supports the valve member. The valve support member has a valve accommodating recess 97. The valve member has a first valve part 98 and a second valve part 94. The first valve part has a front surface with an annular engaging surface engageable with the valve seat 10 a through-hole 96 communicating between the interior of the valve accommodating recess (back-pressure chamber) and the outside of the valve support member, and a communicating passage G communicating between the fluid passage 72 of the tubular member and the back-pressure chamber. The first valve part is subjected to the fluid pressure in the fluid passage 72. The second valve part 94 closes the through-hole 96. 1 5 when the second valve part is moved to open the through-bole, the fluid pressure in the back-pressure chamber reduces, and the first valve part is pushed inward in the valve accommodating recess to separate from the valve seat by the fluid pressure in the fluid passage applied to the first valve part. Consequently, it is possible to maintain the force with which the valve member of the coupling member is pressed against the valve 2 0 seat, and yet the valve member can be opened with a minimal force. Most illustrative drawing is figure 1.
