Improved frozen drink dispensing apparatus includes a container for storing a beverage under pressure in at least a partially frozen state, a normally closed dispensing valve mounted with the container and a manually operable lever for operating the dispensing valve. The dispensing valve has a longitudinal bore communicating with the interior of the container. A conduit depends from the dispensing valve for dispensing the beverage when the valve is in an open position by operation of the lever. A diffusion member is located in the conduit for diffusing the beverage material generally outwardly from a central longitudinal axis of the conduit and upwardly within the conduit, thereby substantially reducing the pressure under which the beverage is dispensed. The diffusion member has an internal chamber communicating with the valve bore and an interior bottom surface, which is sloped upwardly toward an inner wall of the diffusion member. The inner wall of the diffusion member has plural ports through which the beverage flows from the chamber into a dispensing passageway within the conduit. The ports are angled upwardly and cooperate with the interior bottom surface of the diffusion member to direct the material generally outwardly from a central longitudinal axis of the passageway and upwardly within the passageway. Each port is oriented along an axis which is offset laterally relative to a radial axis for imparting a swirling motion to the beverage as the beverage passes through the ports.
