Patent ID: 6840292

Claim:
A vapor storage system for compressing and air or vapor mixture from a fuel storage containment system to reduce the pressure in the fuel storage containment system when the fuel storage containment system is over-pressurized, comprising: a pressure sensor that measures the pressure level in the fuel storage containment system; a controller, wherein said controller is electrically coupled to said pressure sensor to receive the pressure level in the fuel storage containment system; and a compressor pump electrically connected to said controller and under control of said controller wherein said compressor pump is fluidly coupled to the fuel storage containment system; a storage vessel fluidly coupled to said compressor pump; said controller activates said compressor pump to draw the air or vapor mixture from the fuel storage containment system when the pressure level from said pressure sensor exceeds a first threshold pressure level and said compressor pump stores the compressed air or vapor mixture in said storage vessel.
