ABSTRACT:
A jerrycan holds liquid fuel. A cap for the jerrycan includes an air vent valve assembly having an umbrella-shaped check valve. The check valve is sensitive to a pressure differential between an interior of the jerrycan and the atmosphere. As fuel is dispensed from the jerrycan, a volume of an air chamber within the jerrycan increases, thereby decreasing the pressure in the jerrycan and creating a vacuum. The vacuum causes the rate at which fuel is dispensed from the jerrycan to decrease. The check valve dislodges when the pressure within the jerrycan becomes less than the pressure of the atmosphere and additional air is introduced into the jerrycan. The air fills the expanded volume of the air chamber, thereby increasing the pressure, eliminating the vacuum and causing the rate at which fuel is dispensed to increase.
