<p>PURPOSE:To obtain the compact constitution of a coupling by installing a plurality of spring receiving pats in the circumferential direction of a fluid through- hole on a valve body, positioning a seal part on the inside in the radial direction of the fluid through-hole from the projection end of the spring receiving part, and allowing fluid to flow. CONSTITUTION:On a valve body 13, a plurality of spring receiving parts 31 each of which has a projecting shape toward the inner surface of a fluid flow hole 8 are installed, keeping an interval in the circumferential direction of the fluid through-hole 8, and a seal part 18 in the contact with a valve seat 33 is positioned on the inside in the radial direction of the fluid through-hole 8 from the projection end of the spring receiving part 31, and fluid is allowed to flow from between the spring receiving part 31. Accordingly, the fluid flows from between a plurality of spring receiving parts 31 which project towards the inner surface of the fluid through-hole 8 and are arranged, keeping an interval, in the circumferential direction of the fluid through-hole 8, and the flow rate can be increased without increasing the dimension of a socket 2, and the gap between the spring receiving part 31 and the inner surface of the fluid through-hole 8 can be reduced, and the compact constitution can be obtained.</p> |
