Abstract

Apparatus for dispensing cold drinks comprising a cold water supply line in which cold water is flowing continuously, a valve comprising a valve body having passaging, an inlet for delivery of cold water from a first point along said supply line to the passaging, a main outlet for dispensing of cold water from the passaging, a valve member for the main outlet, and an auxiliary outlet for return of cold water from the passaging to a second point along the supply line downstream from the first point, and a Venturi in the supply line for causing a pressure differential in the cold water between the first and second points along the supply line for continuous flow of the cold water from the supply line through the passaging and the auxiliary outlet back to the supply line when the valve member is closed, thereby to assure having cold water on tap in the passaging for being dispensed when the valve member is opened. In a second embodiment the valve body has a syrup passage for flow of syrup to the main outlet and a syrup valve, the syrup passage being in heat-exchange relation with the continuously flowing cold water.
