Carbonated beverage water is prepared on flow demand by a process that combines respective flow streams of water and carbon dioxide in a mixing venturi. Downstream of the venturi, the mixture of water and carbon dioxide is passed through a static mixer prior to dispenser discharge.

Tankless beverage water carbonation process and apparatus

A line strainer for screening fluid flow in a small diameter conduit is constructed with an integral housing of clear or transparent thermoplastic polymer. A fluid flow channel through the housing center is terminated at opposite ends by sonically welded end fittings. Internally of the housing, a screen chamber is separated from a flow meter chamber by a screen support hub with flow diversion passages. The screen chamber confines a conically formed screen mesh for passing substantially all flow through the housing. The flow meter chamber has conically tapered walls that support radial fins projecting from the walls inwardly to a cylindrical void that confines the metering ball to displacement along the housing axis. A spring bearing against the metering ball resiliently biases the ball toward the flow restriction passage and against the fluid flow direction. The spring bias and conically tapered meter walls cooperate with the flow stream and metering ball to stabilize at a position along the housing axis that is proportional to the flow rate through the screen. As the screen mesh fills to increase flow stream resistance, the metering ball approaches the flow restriction passage signaling a reduced flow rate. The degree of plugging or filling of the screen mesh is therefore indicated by the relative position of the metering ball for a substantially constant pressure source. Additionally, pump performance or system blockage could also be detected by the ball position in the flow meter chamber.

A moderately high pressure, sliding vane pump is fabricated from low modulus plastic by routing high pressure fluid away from the central pump perimeter and into a bearing gland chamber for discharge porting. Port fittings are push socket connections that are sealed by O-rings and held in place against fluid pressure ejection by a saddle plate that cross-pins to the port boss.
