Abstract
A hydrogen gas charging device (1) is provided with a gas supply pipeline (5), a hose (6), a nozzle (7), a breakaway coupling (31) and a speed reduction mechanism (41). The breakaway coupling (31) is provided between the gas supply pipeline (5) and the hose (6) and separates the gas supply pipeline (5) and the hose (6) from each other in an emergency. When the breakaway coupling (31) is separated to a nozzle-side coupling (31A) and a counter nozzle-side coupling (31B), the speed reduction mechanism (41) reduces a speed of the separated nozzle-side coupling (31A). The speed reduction mechanism (41) is provided with a hose guide (41A) and a buffer member (41B) provided in the hose guide (41A).
Claims4
A fuel gas supply device comprising:
- a gas supply pathway for supplying fuel gas to a tank;
- a nozzle that is provided on the side of one end of the gas supply pathway to be connected to the tank;
- and
- a breakaway coupling that is provided in the middle of the gas supply pathway to separate the gas supply pathway to one side that is on the side of the nozzle and the other side that is on the opposite side to the nozzle side, characterized by including:
- a speed reduction mechanism located closer to the side of the nozzle than the breakaway coupling in the middle of the gas supply pathway, wherein the speed reduction mechanism, when the breakaway coupling is separated to a nozzle-side coupling and a counter nozzle-side coupling, reduces a speed of the separated nozzle-side coupling.
