Abstract

A cock (10) that receives and discharges the carbonated water from a nozzle (70) includes: a first flow path (4S); and a second flow path (46). A flow path transverse Closs-section has an annular shape. The second flow path has an outer diameter larger than that of the first flow path and having a flow path cross-sectional area smaller than that of the first flow path; and a shaft (50) which forms the inner circumferential surface of the second flow path. the shaft having a ring-shaped groove (52) formed over the outer circumference of the shaft in a part of the second flow path that is connected to the first flow path, wherein a longitudinal center axis line (C1) of the first flow path is nonparallel to and does not intersect with a longitudinal center axis line (C2) of the second flow path.

First claim

The invention claimed is:

1. A carbonated water cock receiving pressurized carbonated water and discharging the pressurized carbonated water from a nozzle, the carbonated water cock comprising:
a body:
a shaft;
a first carbonated water flow path formed in the body: and
a second carbonated water flow path connected to a downstream side of the first carbonated water flow path, the second carbonated water flow path extending in a direction different from the first carbonated water flow path, the second carbonated water flow path exhibiting an annular-shaped flow path cross section, wherein an outer diameter of the second carbonated water flow path is larger than an outer diameter of the first carbonated water flow path, but a sectional area of the second carbonated water flow path perpendicular to a direction of flow is smaller than a sectional area of the first carbonated water flow path perpendicular to a direction of flow; and
a longitudinal center axis of the first carbonated water flow path not being parallel to a longitudinal center axis of the second carbonated water flow path,
wherein the body has a bore configured to form the second carbonated water flow path between the bore and the shaft fixed to the body within the bore,
wherein the shaft has a ring-shaped groove formed around an outer circumference of the shaft at a part of the second carbonated water flow path that is connected to the first carbonated water flow path,
wherein the first carbonated water flow path and the second carbonated water flow path are connected so that among two lines defining a contour of the first carbonated water flow path, a line further from the center axis of the second carbonated water flow path is a tangent of a circle defining a contour of an outside of the annular shape of the second carbonated water flow path, and
wherein a sectional shape of the ring-shaped groove of the shaft is a bow shape and a total area of an area of the bow shape and an area of a rectangle formed by a chord of the bow shape and a width of the second carbonated water flow path is less than 50% of the flow path sectional area of the first carbonated water flow path.

2. The carbonated water cock according to claim 1 , wherein the total area of the area of the bow shape and the area of the rectangle formed by the chord of the bow shape and the width of the second carbonated water flow path is 33% of the flow path sectional area of the first carbonated water flow path.
