TANK SAFETY VALVE

摘要

A fuel tank protection valve is provided. The valve consists an all-metal diaphragm suitable for operating at low temperatures. The valve includes a tank duct connected to the fuel tank and a second duct connected to a filter. A sealing device is connected to the diaphragm adapted to open and close a passage between the tank duct and the second duct. The valve further includes a one-way, mushroom type valve to allow gas flow from the filter to the gas tank. A clamp cover with air passage openings is included to allow equalization of the pressure between the ambient air and the air pressure within the cover space.
