    • The present invention relates to a conduit for conducting gasified liquid, which has a flow restrictor arranged in in-line relation therewith. The restrictor itself comprises an at least one aperture (although two or more can be used in series), with each such being adapted to pass the gasified liquid flowing through the conduit and across a pressure drop from a higher-pressure upstream side of the aperture to a lower-pressure downstream side of the aperture. The aperture is operable to moderate the rate of change in pressure over a transitional pressure drop to mitigate the formation of localized pressures below a critical pressure at which off-gassing from the carbonated liquid results in substantial foam formation. The conduit may take the form of a dispensing tube for use in dispensing an alcoholic beverage from a keg, the tube having a flexible wall deformable under the influence of a restricting actuator to control the partial collapse of the wall and thereby form the restrictor. The tube or flow diameter downstream of the restrictor only gradually or slowly increases.
    • 本发明涉及一种用于导入气化液体的导管,其具有与其成直线关系布置的限流器。 限流器本身包括至少一个孔(尽管可以串联使用两个或更多个),其中每一个适于使流过导管的气化液体和穿过孔的较高压力上游侧的压降 到孔的低压下游侧。 该孔径可操作以调节压力相对于过渡压降的变化率,以减轻局部压力的形成,该压力低于临时压力,在该临界压力下,来自碳酸液体的脱气导致大量的泡沫形成。 导管可以采取分配管的形式,用于从小桶中分配酒精饮料,该管具有柔性壁,该柔性壁在限制致动器的影响下可变形,以控制壁的部分塌陷,从而形成限制器。 限流器下游的管或流径仅逐渐或缓慢增加。
