Limiting the pressure in the ORVR vent line if fuel tank overfilled or if gasoline pump nozzle faulty (does not switch off).

Pressure relief valve design

Housing with internal diaphragm which seals off the line to the pressure relief valve by means of a spring.

Pressure relief valve function

The diaphragm lifts off at a pressure of approx. 60 to 90 mbar. The fuel overflow line to atmosphere opens. Air is admitted to the diaphragm chamber.
