Abstract
A liquefied gas fuel filling system provided with a filling and pressure-balanced receptacle at a vehicle side combined with a filling and pressure-balanced nozzle at a station side connected with a storage tank, and an excess flow prevention valve provided in a pressure-balanced line for making the filling and pressure-balanced receptacle and a gas-phase region of a fuel tank contact each other. An orifice is provided in a pressure-balanced receptacle of the filling and pressure-balanced receptacle, thereby enabling the fuel tank to be smoothly filled with liquefied gas even when the outside air temperature rises.
