PROBLEM TO BE SOLVED: To prevent a liquid from dripping from the tip of a nozzle 6 after filling is completed. SOLUTION: There are provided a valve housing 4 having a liquid passage 2 formed inside and the nozzle 6 formed to connect with the end of the valve housing. A first valve element 20 capable of seating on a first valve seat 22 on an internal surface of the valve housing 4 opens/closes the liquid passage 2, and in addition a second valve element 36 provided on a rod 34 liftably inserted into the first valve element 20 is inserted into the nozzle 6, so that a liquid passage 10 can be opened/closed below the first valve element 20. After the first valve element 20 is seated on the first valve seat 22 and the second valve element 36 is inserted into the nozzle 6 to have the liquid passages 2 and 10 closed, and thus the filling is completed, the second valve element 36 is slightly moved up. Capacity on an outlet of the nozzle 6 increases to have remaining filler liquid sucked, preventing it from dripping. COPYRIGHT: (C)2011,JPO&INPIT |
