VAPOR VALVE FOR STORAGE TANK

摘要

A tank assembly including a tank for storing fluid, the tank having a fluid refill path. The assembly includes a blocking valve coupled to the tank, the blocking valve being positioned in the fluid refill path and configured to selectively generally seal the fluid refill path. The assembly further includes an overfill valve in fluid communication with the fluid refill path and configured to generally block the fluid refill path when sufficient fluid is in the tank. The blocking valve is positioned to prevent vapors which are introduced into the fluid refill path via the overfill valve from escaping from the tank.
