Abstract
Disclosed is a breather valve for controlling a pressure of a transfer channel of a valve assembly. The valve assembly controls charging and discharging of hydrogen in a hydrogen fuel cell-based vehicle. The breather valve includes a vent ring movably received in a distal portion of the transfer channel and having a ventilation hole communicating with a main portion of the transfer channel; and a vent valve received in the distal portion of the transfer channel and screw-coupled to the transfer channel to open or close the ventilation hole.
Claims5
A breather valve for controlling a pressure of a transfer channel of a valve assembly, wherein the valve assembly controls charging and discharging of hydrogen in a hydrogen fuel cell-based vehicle, wherein the breather valve comprises:
- a vent ring movably received in a distal portion of the transfer channel and having a ventilation hole communicating with a main portion of the transfer channel;
- and
- a vent valve received in the distal portion of the transfer channel and screw-coupled to the transfer channel to open or close the ventilation hole,
- wherein the vent ring is positionally biased by a pressure of the transfer channel and thus is in close contact with the vent valve, thereby to block the ventilation hole.
