Rapid comestible fluid dispensing apparatus and method employing a diffuser

A method of dispensing a comestible fluid, comprising:

• maintaining comestible fluid under pressure in a fluid line, the fluid line terminating at a nozzle closed against flow of comestible fluid therethrough;
• opening the nozzle to permit flow of the comestible fluid through the nozzle;
• and
• reducing velocity of flow of the comestible fluid through the nozzle using a diffuser in fluid communication with nozzle portion having a larger, substantially constant diameter.

A comestible fluid dispensing apparatus, comprising:

• a nozzle;
• a dispensing outlet;
• an internal chamber located at least partially in the nozzle upstream of the dispensing outlet and in fluid communication with the dispensing outlet, the internal chamber including:
• a diffuser having walls defining an increasing internal chamber cross sectional area toward the dispensing outlet;
• and
• a section downstream of the diffuser and having a substantially constant cross sectional area toward the dispensing outlet;
• and
• a valve movable to open and close the dispensing outlet.

A method of dispensing comestible fluid, comprising:

• receiving comestible fluid in a fluid chamber;
• opening a valve at a dispensing outlet of the fluid chamber;
• passing comestible fluid into an entrance of a diffuser in the fluid chamber, the entrance having a cross sectional area;
• passing comestible fluid through the diffuser in the fluid chamber;
• discharging comestible fluid from an exit of the diffuser having a cross sectional area larger than the cross sectional area of the diffuser entrance;
• receiving comestible fluid in a portion of the fluid chamber having a substantially constant cross sectional area downstream of the diffuser;
• and
• discharging comestible fluid past the opened valve and through the dispensing outlet.
