AERATING APPARATUS ABSTRACT A portable carbonating apparatus of the type comprising a pressure vessel (11) and a header tank (13) has a bottom inlet (34) and a top outlet (38) controlled by respective valve pistons (36, 39) which are rigidly connected together by a connecting rod (40). The pistons (36, 39) have equal areas exposed within the pressure vessel, so as to be pressure balanced at all times. The top value piston (39) also acts to control opening and closing of a venting port (44) to ensure venting of pressure from a head space (42) during initial opening movement of the valves. The header tank is self-valved (19) and is detachable from the apparatus.
