PURPOSE:To regulate outflow of liquid, where occasion demands and to ensure operation, by a method wherein, when a gripping force is exerted on a radial displacement member, an axial movement member and a valve seat approach each other to open a valve. CONSTITUTION:When a gripping force is exerted on a threadform member 11, an axial movement member 4, a valve seat 5, and a rear shaft 12 are pulled to a position where, with a spring 10 contracted, the tip of a slide pipe 9 is forced into contact with the rear end of the axial movement member 4. In which case, a valve 6 is relatively moved backward from the valve seat 5 to provide a gap. Ink flows between the valve 6 and the valve seat 5, and flows through an ink introduction hole 7a to a leg 7. The ink is induced by an ink induction core 2 and flows to a point 1. When a gripping force applied on the threadform member 11 is returned to its original state, the valve 6 is closed to shut off the passage of the ink. |
