Abstract: 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.

Abstract: 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.

Abstract: 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.
