Filed: 1991-10-02
Abstract: PURPOSE:To prevent a liquefied gas from leaking outward by projecting a filling pipe toward an inlet hole of a nozzle-receiving mouthpiece when a nozzle body is drawn to the side of the nozzle-receiving mouthpiece, and releasing a main valve when the filling pipe is projected to reach a final amount of projection. CONSTITUTION:When an engaging arm 22 is engaged with the part to be engaged of a reservoir to be gass-filled, and a nozzle body 20 is drawn to the side of a nozzle connecting mouth of the reservoir, an abutting tool 35 abuts on the nozzle-receiving mouthpiece 6, and a filling pipe 36 is projected from a piston part 32. Further, when the filling pipe is projected from the piston part 32 a specified amount or more detecting units 45, 48 detect the amount of projection to release a main valve 51.
