Abstract
A home carbonated beverage dispenser includes a transfer valve for conducting carbonated liquid from a carbonation reservoir to an outlet spout. A characterizing feature of the device and of the valve resides in the provision of complemental arcuate guide surfaces on the relatively movable surfaces of the valve which are brought into registry in the dispensing condition of the valve, whereby fluid flow through the valve is effected with a minimum of turbulence. A restrictor orifice is formed at the port, the orifice being defined by arcuate surfaces which mate with and provide a smooth continuation with elements of the movable valve components, thereby further to minimize turbulence and assure minimal loss of carbonation.
