A connector for connecting a carbon dioxide cylinder (200) to a carbonation apparatus includes a female part having a cylindrical recess (218) for receiving a male part (232) carried by the carbonation apparatus. An axially movable actuator (260) extending through the male part projects through a central passage (226) at the bottom of the cylindrical recess to engage a valve member (208) for opening the valve. The actuator (260) is in three parts (262, 280, 282) and the centre part (280) itself forms a valve which is closed when the actuator is depressed for supplying carbon dioxide from the cylinder (200) to a carbonation chamber but which, when the actuator is released, may open in response to pressure in the carbonation chamber for supplying carbon dioxide therefrom to another part of the apparatus, such as a concentrate supply device. |
