ABSTRACT:
A carbon dioxide fill manifold which is designed to provide an end-user with an uninterrupted supply of carbon dioxide gas, while at the same time eliminating the necessity of transporting individual, conventional pressurized bottles to be refilled. The carbon dioxide fill manifold includes a fill line having a fill line valve therein for introducing liquid carbon dioxide into the system, one or more liquid chambers communicating with the fill line for receiving and storing liquid carbon dioxide, a liquid transfer line extending from the fill line to an atomizer, a service line connected to the atomizer and fitted with at least one vapor container for receiving gaseous carbon dioxide generated in the atomizer and a service line valve provided in the service line for servicing the end user with gaseous carbon dioxide. In an optional embodiment a bleeder valve line and bleeder valve are also connected to the atomizer, in order to determine when the system is filled with liquid and gaseous carbon dioxide and an in-line pressure relief valve, located in the liquid transfer line, serves to periodically replenish the supply of gaseous carbon dioxide to the vapor container(s) responsive to a selected pressure differential at the pressure relief valve.
