DEFINITION

Classification: 48/4

Structures whereby water is fed to the carbid. The water is fed by gravity and controlled by the pressure of the gas in the generator or by the operation of the gas-holder. It also includes structures for feeding the water to the carbid by capillary attraction. This subclass includes generators in which water is fed by gravity to the top of the carbid and automatically regulated by the gas-pressure in the generator. A hand-valve is employed to turn on and off the water-feed.
