Abstract
A micro-leakage regulating valve, in which a metal block has a through hole and a tapped hole extending from one side of the metal block and communicating with the through hole at the center thereof. The through hole has inserted therethrough a capillary metal tube. At one end of the through hole a sealing member provides a seal between the outer peripheral surface of the capillary metal tube and a surrounding wall surface of the metal block. An adjusting screw is screwed into the tapped hole, to crush the capillary metal tube to a desired degree, setting a desired flow rate.
