Shown is a horizontal model of a continuous flow motorless carbonator, which carbonates water from a pressurized source as it is drawn, with a pivoted float element connected mechanically to a gas inlet valve assembly and having an extended arm to receive impact of inlet water, the net force due to impact and weight of the float less its displacement of water, being conveyed to the gas inlet valve to control the flow of inlet gas directly, and the flow of inlet water indirectly, so that the flow rate of water equals the flow rate of carbonated water out and a constant liquid level is maintained during a draw. A vertical model with dual water inlets and a float member resting directly on a gas inlet valve and in position to receive water impact from one of the dual inlets is also shown, employing the same basic principles.

A continuous flow carbonator for mixing inlet carbonating gas and inlet water continously while carbonated water is being dispensed, the inlet flow rate of gas and water being equal to the outlet flow rate of water and gas mixture, said inlet water having an inherent capacity to produce an impact force of magnitude F, equal to the product of its mass flow rate and velocity, on a surface normal to its velocity, said carbonator comprising a tank, a float assembly in said tank responsive to the level of liquid in the tank and a surface on the assembly receptive to and responsive to the impact of at least a portion of said inlet water, regulator means in said tank, including an orifice and closure, for controlling the flow of said inlet gas and the static pressure in the tank responsive to a resultant force delivered to said regulator means to bias said closure against said orifice, the greater the force the greater the restriction and the less said static pressure, said force being the resultant of a weight force due to float weight less the weight of water it displaces and of an impact force due to impact of inlet water on said surface of the float assembly, and mechanical connecting means for delivering said resultant force from said float assembly to said regulator means, said impact force being diminished in its delivered amount to said regulator means to an amount less than magnitude F, and said weight force being undiminished in its delivered amount to said regulator means.
