Abstract
A non-aerating fluid dispensing nozzle for dispensing fluid into a receiving tank has a vapor control and containment mechanism for vapors formed in the receiving tank. The mechanism has a chamber disposed within the housing of the nozzle and a gas passage that has a first end connected to the chamber and a second end connected to an intake aperture disposed near the distal end of the discharge nozzle. A pump is disposed in fluid flow communication with the chamber for pumping gases from the fluid receiving tank into the chamber through the gas passage during fluid flow through the nozzle.
