Abstract
A dispensing head for use in a heated water and chilled water dispensing system operated at atmospheric pressure has a valve body having a connecting means for attaching the dispensing head at a point of use generally remote from the dispensing system, said valve body has a common discharge spout for the heated water and chilled water delivered thereto from the dispensing system, a first control valve assembly having an inlet in communication with the heated water section of the dispensing system acts to control delivery of the heated fluid through a first cross-over passage in communication with the discharge spout, a second control valve assembly having an inlet in communication with the chilled water section of the dispensing system acts to control delivery of the chilled water through a second cross-over passage in communication with the discharge spout, vent means is formed in the dispensing head for venting the hot water section of the dispensing system to atmosphere, and a check valve is operatively associated with said common discharge spout to prevent any unwanted mixture of heated water and chilled water during operation of the system. Additionally, the combination of said dispensing head as above described with a heated water and chilled water dispensing system operated at atmospheric pressure includes, a first assembly for heating and storing heated water to be dispensed from said system, a second assembly for chilling and storing chilled water to be dispensed from said system, a first conduit connecting the first control assembly to said heating and storing assembly for heated water, a second conduit for connecting the second control assembly to the chilling and storing assembly for the chilled water, and a connecting conduit to provide communication between the heated water section of the dispensing system and the vent means in the dispensing head.
