Abstract
Official abstract text for this publication.
A suction method that sucks inside of a filling nozzle used for supply of hydrogen by using a suction nozzle that is engaged with the filling nozzle, the suction method comprising: evacuating a vacuum chamber by using a vacuum pump; and sucking inside of the suction nozzle by using the evacuated vacuum chamber.
First claim
Opening claim text (preview).
What is claimed is: 1 . A suction device that sucks inside of a filling nozzle used for supply of hydrogen, the suction device comprising: a suction nozzle configured to be engaged with the filling nozzle; a vacuum chamber configured to suck inside of the suction nozzle; and a vacuum pump configured to evacuate the vacuum chamber. 2 . The suction device according to claim 1 , wherein at least either the vacuum chamber or the vacuum pump is located in a place that does not require hydrogen explosion protection. 3 . The suction device according to claim 1 , wherein suction of the suction nozzle by the vacuum chamber is performed in response to an operator's instruction and is then performed again after a predetermined time interval. 4 . The suction device according to claim 1 , further comprising a mechanism configured to change and set a depression angle of the suction nozzle. 5 . The suction device according to claim 4 , wherein the mechanism sets the depression angle to face the suction nozzle upward during suction by the vacuum chamber, compared with a state that the suction nozzle and the filling nozzle are not engaged with each other. 6 . The suction device according to claim 4 , wherein the mechanism sets the suction nozzle to face in a horizontal direction when suction by the vacuum chamber is performed. 7 . The suction device according to claim 4 , wherein the mechanism sets the depression angle to 45 degrees when suction by the vacuum chamber is not performed. 8 . The suction device according to claim 1 , comprising a plurality of the vacuum chambers. 9 . The suction device according to claim 8 , wherein during suction of the suction nozzle by one of the plurality of vacuum chambers, another of the plurality of vacuum chambers is evacuated by the vacuum pump. 10 . The suction device according to claim 1 , wherein suction power by the vacuum chamber is higher than suction power by the vacuum pump. 11 . A suction method that sucks inside of a filling nozzle used for supply of hydrogen by using a suction nozzle that is engaged with the filling nozzle, the suction method comprising: evacuating a vacuum chamber by using a vacuum pump; and sucking inside of the suction nozzle by using the evacuated vacuum chamber.
