Carbonator and liquid level control

Abstract From the Canadian patent

A carbonator has a pressure vessel a nozzle for introducing, water and carbon dioxide into the vessel water level control including, a reed switch and a magnetic float for sensing the level of water and operating the reed switch; a novel housing encloses the level control and provides a unidirectional fluidically affected delay in sensing and control response to a rising water level during filling of the carbonator; the housing has a water chamber which encloses the level sensing float a, water inlet into the water chamber near the level of a maximum desired water level in the vessel, a water outlet from the bottom of the water chamber, and a check valve in the water outlet for allowing …
