DEFINITION

Classification: 48/13

Apparatus in which no valve is employed to regulate the feed of water to the generator. It includes means for displacing water, a flexible tube, a siphon or tilting vessel operated by the gasholder.

(1) Note. In this subclass the feed of water is controlled by the gas-pressure in the generator or holder acting upon the column of water to be fed. It also includes means carried by the gas-holder not otherwise classified under the subclasses of "Valveless feed".
