Abstract
Abstract A tapping cock for mixed drinks which comprises a feeding conduit each for fruit syrup and for carbonated water. Both said conduits are disposed in a cock housing. A discharge valve is operable from the outside in each of the conduits and opening and closing, respectively, the conduits. An outlet mouth piece receives the conduits. A control valve is disposed in the cock housing between the feeding conduit for fruit syrup and the discharge valve coordinated thereto holding constant the passing quantity thereof, independently from the pressure, temperature and viscosity, and the control valve having outlet openings disposed adjacent to the corresponding discharge valve.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A tapping cock for mixed drinks, comprising a feeding conduit each for fruit syrup and for carbonated water, both said conduits being disposed in a cock housing, a discharge valve for each conduit operable from the outside of said conduits and opening and closing said conduits, an outlet mouth piece receiving said conduits, a control valve disposed in a cylindrical bore in said cock housing between said feeding conduit for fruit syrup and said discharge valve coordinated thereto, said control valve comprising a hollow piston equipped with an end wall pierced centrally in a direction towards said feeding conduit for fruit syrup, and a cylinder bushing, fitted in said cylindrical bore and having outlet openings, and said hollow piston slidably guided in said cylinder bushing, an adjustable abutment, said hollow piston supporting itself operatively on said abutment by means of a pressure spring, said outlet openings of said cylinder bushing being disposed adjacent to said corresponding discharge valve.
Claim 2
Dependent Claim
158 words
A tapping cock for mixed drinks, comprising a feeding conduit each for fruit syrup and for carbonated water, both said conduits being disposed in a cock housing, a discharge valve for each conduit operable from the outside of said conduits and opening and closing said conduits, an outlet mouth piece receiving said conduits, a control valve disposed in a cylindrical bore in said cock housing between said feeding conduit for fruit syrup and said discharge valve coordinated thereto, said control valve comprising a hollow piston equipped with an end wall pierced centrally in a direction towards said feeding conduit for fruit syrup, and a cylinder bushing, fitted in said cylindrical bore and having outlet openings, and said hollow piston slidably guided in said cylinder bushing, an adjustable abutment, said hollow piston supporting itself operatively on said abutment by means of a pressure spring, said outlet openings of said cylinder bushing being disposed adjacent to said corresponding discharge valve.
Claim 3
Dependent Claim
72 words
The tapping cock, as set forth in claim 1, which includes a cylindrical stopper received in said cock housing and having a longitudinal bore, said feeding conduit for fruit syrup is disposed in said bore cylindrical stopper, the backside of said cock housing defining a cylindrical bore extending beyond one half of the length of said cock housing, and said cylindrical stopper and said control valve are disposed in said cylindrical bore.
Claim 4
Dependent Claim
43 words
The tapping cock, as set forth in claim 1, wherein the cross-section of the opening of said end wall of said hollow piston is dimensioned such, that it reaches at best to said feeding conduit for fruit syrup disposed opposite and spaced apart.
Claim 5
Dependent Claim
31 words
The tapping cock, as set forth in claim 3, wherein said abutment comprises a plate with a sealing ring engaging said cylindrical bore and a threaded pin adjustable from the outside.
Claim 6
Dependent Claim
140 words
The tapping cock, as set forth in claim 1, further comprising valve rods in each conduit cooperating with said discharge valves, both said conduits change within the range of said valve rods into downwardly directed channels, whereby said channel feeding carbonated water terminates laterally in said outlet mouth piece, and said channel feeding syrup has an extension piece projecting into a central bore of said outlet mouth piece, said outlet mouth piece has an open annular space to be fed through said channel feeding carbonated water, a wall drawn upwardly towards said central bore has longitudinal slots, said outlet mouth-piece is screwable to the bottom side of said cock housing by means of an annular collar, and said outlet mouth-piece is securable to the bottom side of said cock housing by means of an annular collar by a clamping means.
