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.

[ It is claimed:] [1.] In an apparatus for dispensing material in at least a partially frozen state, said apparatus having a container for storing the material under pressure; a valve mounted with said container for controlling the dispensing of the material, said valve having a valve body with a bore communicating with an interior of said container; closure means disposed in said bore and being adapted to close said bore to prevent the material from passing therethrough when said closure means is in a first position; actuating means for moving said closure means to a second position wherein material is allowed to pass through said bore; and a conduit depending from said valve body, said conduit having an internal passageway through which the material is dispensed when said closure means is in said second position, wherein the improvement comprises:diffusion means for diffusing the material generally outwardly from a central longitudinal axis of said passageway and upwardly within said passageway, said diffusion means including a diffusion member located in said passageway and having an open top, a closed bottom and at least one wall extending between said top and said bottom, said at least one wall defining a chamber within said diffusion member, said chamber communicating with said bore through said open top, whereby material flows under pressure into said chamber when said closure means is in said second position, said diffusion member having an interior bottom surface which is sloped upwardly toward said at least one wall and said at least one wall having at least one port extending outwardly and upwardly through said at least one wall from said chamber to said passageway, whereby material flowing under pressure into said chamber when said closure means is in said second position is directed outwardly and upwardly within said passageway.
