Regulator for controlling the flow of carbonated beverages

A regulator for controlling the flow of carbonated beverages, provided with:

• a main body comprising at least two parts comprising a downstream part, having a cavity and a hole for the exit of the carbonated beverage, and an upstream part, having a cavity and an inlet hole for the carbonated beverage under pressure, or
• the main body comprising at least three parts comprising the downstream part, the upstream part and a central part having a cavity;
• the at least two parts or at least three parts comprise at least two attachable and detachable parts, wherein the at least two parts are equipped with frustum-shaped cavities that accommodate a double conical part,
• wherein the double conical part comprises an upstream cone portion, the diameter of which increases in the direction of the carbonated beverage flow, and a downstream cone portion, the diameter of which decreases in the direction of the carbonated beverage flow;
• wherein the cavity of the downstream part or the cavity of the central part, or both, have the shape of a frustum-cone, and have their internal walls with the same inclination, in relation to a longitudinal axis, as the downstream cone portion;
• wherein the cavity of the upstream part in the shape of a frustum-cone has its internal walls having the same inclination, in relation to the longitudinal axis, as the upstream cone portion;
• wherein an end of the downstream cone portion transfers the force exerted by the carbonated beverage pressure on the upstream cone portion, including the force exerted on a convex end of the upstream cone portion of the double conical part, to an elastomeric material that deforms depending on the pressure of the carbonated beverage;
• wherein the elastomeric material is also housed in a support coupled to the downstream part or in a movable support coupled to the downstream part;
• the carbonated beverage flows through a space formed between the movable support for the elastomeric material and the cavity of the downstream part or the central part, or at a junction between the downstream part and the central part;
• the movable support for the elastomeric material is cylindrical and is equipped with arms that project in the radial direction of the movable support and accommodate themselves in cuts of the main body;
• the arms also project in an axial direction in the direction of the flow of the carbonated beverage;
• and
• the arms are provided with guide pins being smaller in width than the arms and projecting in the axial direction, but in the opposite direction to the flow of the carbonated beverage, and the guide pins are accommodated in recesses arranged in the cuts.
