ABSTRACT:
A vented inlet including a lower pipe to be mounted generally vertically within a tank and an upper pipe supported above and generally axially aligned with the lower pipe to define a vent space therebetween. The internal diameter of the upper pipe is smaller than the internal diameter of the lower pipe, so that liquid flowing downwardly through the upper pipe falls through the vent space, into the lower pipe, and consequently into the tank; however, compressed air flowing through the upper pipe is vented through the vent space to the air surrounding the inlet.
