Device for dispensing effervescent beverages and a three-way valve

A three-way cock comprising a hollow cylinder-shaped housing (26) with two inlet or outlet ducts (27) and (28) and one outlet or inlet duct (29) and a means installed inside the housing with a control lever (30) for switching on or switching off one of the inlet or outlet ducts (27 and 28) with the outlet or inlet duct (29), wherein the hollow cylinder-shaped housing (26) of the cock has three consecutively arranged annular compartments (31, 32, and 33), the inlet or outlet ducts (27) and (28) being connected to the first compartment (31) and the third compartment (33) and the outlet or inlet duct (29) being connected to the second (middle-positioned) compartment (32);

• the means for switching on and switching off the outlet or inlet ducts (26) and (27) contains two valves (34) and (35) with elastic face seals (36) and (37) having axial ducts with elastic annular seals (38) and (39) arranged in the second compartment (32) of the housing of the cock and positioned in the saddles of the valves (34) and (35) with an option of an axial reciprocating movement thereof;
• and a stem (40) arranged inside the housing (26) with an option of an axial reciprocating movement thereof, one end (41) of the stem going out the housing through the end wall thereof and kinematically connected to the control lever (30) and the other end (42) thereof positioned in the first compartment (31) of the housing and sealed to the wall thereof by means of an annular elastic seal (43), passes through the axial ducts of the valves (34) and (35) with annual elastic seals and is kinematically connected thereto by means of a spring (44) which is located around the stem (40) between the annular valves (34) and (35) and presses to the saddles of these valves formed by ledges (45) and (46) made in the wall of the housing (26) between the first, second, and third compartments (31, 32, and 33) thereof and annular ledges (47) and (48) made on the stem (40);
• and further the end (42) of the stem on the side opposing the lever has an axial duct (49) with an open end having a length matching the size of the first compartment (31) of the housing and communicating with this compartment via radial through holes (50) made in the stem (40) in front of the plugged end of the axial duct (49) of the stem, wherein the first compartment (31) and the third compartment (33) are hermetically isolated from the second compartment (32) by means of the aforementioned valves (34 and 35) which are pressed by the spring (44) in the axial direction to the saddles of these valves.

An apparatus for a manual dispensing of foaming and/or carbonated beverages to uncovered container comprising a housing (52) with a stage (53) for positioning an uncovered container (54) thereon and a filling pipe (55) mounted thereon for feeding a beverage, one end of the pipe (55) being arranged above the place where the uncovered container (54) is positioned, wherein the apparatus is equipped with a cap (56) which is hermetically fastened to the stage, with an option of being disconnected, under which there are the filling pipe (55) and the place where the uncovered container (54) is positioned;

• a unit for fastening the cap and supplying or removing the container (54) from under it;
• and a unit for supplying under pressure a beverage or gas to underneath the cap (56) and removing the gas therefrom containing a flow switch (59), through which the inlet end of the filling pipe (55) is connected to a beverage supply pipeline (60) for supplying the beverage from the isobaric storage and a gas supply pipeline (61) for supplying the gas from the gas cylinder;
• and a pipe (62) having one end thereof connected to the internal space of the cap and the other connected with the atmosphere through the flow switch (59), wherein the flow switch (59) is embodied in the form of two three-way cocks (63 and 64) equipped with control levers (5 and 30);
• an outlet duct (4) of the first cock (63) is connected to the filling pipe (55);
• two inlet ducts (3 and 2) are connected with, respectively, the gas supply pipeline (61) for supplying the gas from the gas cylinder and the beverage supply pipeline (60) for supplying the beverage from the isobaric capacity;
• and the second cock (64) contains an inlet duct (28) connected via a pipeline to the end of the pipe (62) for removing the gas from under the cap (56) and two outlet ducts (29 and 27) for gas release, one being connected to the second cock (64) via a throttle (66) for controlling the leaving gas flow rate from the removable cap (56).
