Abstract
A pressure relief valve assembly includes a housing, a diaphragm assembly separating the housing into a sensing pressure section and a tank pressure section, the sensing pressure section configured to sense both atmospheric pressure and the pressure in the tank pressure section and the tank pressure section is configured to only sense the pressure in the tank pressure section, an orifice disposed between the sensing pressure section and the tank pressure section allowing fluid to flow in through the orifice when the pressure in the sensing pressure section is less than the pressure in the tank pressure section fluid to flow out through the orifice when the pressure in the sensing pressure section is greater than the pressure in the tank pressure section.
