<p>PURPOSE: To provide a coupler for high pressure fluid, namely, a coupler capable of decreasing pressure loss of fluid to pass in the coupler. CONSTITUTION: A coupler is composed with a body 21, a nose 22 and a collar 23 for connecting them to each other, and in which poppet valves 241 , 242 are mounted on the body and the nose, and pressure loss of fluid is decreased by fitting straightening rings 1 on the back surfaces of the poppet valves. Accordingly, pressure loss can be decreased by mounting the straightening rings on the back surfaces of the poppets, and the effect is large, particularly, in connecting of couplers in series.</p> |
