INFUSION NOZZLE

摘要

PROBLEM TO BE SOLVED: To properly carry out both of fine adjustment for gradually decreasing the flow rate of a liquid flowing out through a nozzle and fine adjustment for gradually increasing the flow rate. SOLUTION: A tubular part 10 of a connector body 1 to be inserted into a supply pipe P of a liquid W is gradually tapered in the inner diameter toward the tubular tip end 10a in the insertion side into the supply pipe P. An adjuster body 2 has a shaft part 20 to be inserted into the tubular part 10 of the connector body 1. The shaft part 20 of the adjuster body 2 is gradually tapered in the outer diameter toward the shaft tip end 20a in the insertion side in to the tubular part 10 of the connector body 1. The axial part 20 is so composed as to have a proper thickness to form a fine gap S for forming a flow path of the liquid W between the inner circumferential face 10c of the tubular part 10 of the connector body 1 and the outer circumferential face 20b of the shaft part 20 in the longitudinal direction of the tubular part 10.
