Tap for dispensing carbonated beverages

Claim 2

A tap for dispensing carbonated beverages, comprising: a tap body having a chamber therein extending through an outer surface of the body; a supply passage in said body extending laterally from said chamber; a valve member slidable in said chamber and extending outwardly of said body through said outer surface and having an outer end; a dispensing passage in said valve member extending inwardly from its outer end then curving smoothly laterally toward said supply passage, said supply passage and all of said dispensing passage being of the same uniform cross section; a control member pivotally carried by said body and linked to said valve member for sliding said valve member in said chamber between a first position wherein said curved portion of said dispensing passage is aligned with said supply passage and a second position wherein said dispensing passage is displaced from said supply passage; said chamber being provided with a circular inwardly extending rib, between said supply passage and said outer surface, surrounding said valve member, a groove around said valve member adjacent the inner end thereof and a sealing ring in said groove sealingly engaging said rib when said valve member is in said second position; and said chamber and valve member being provided with cooperating stop shoulders limiting movement of said valve member to said first position.

Claim 3

A tap for dispensing carbonated beverages, comprising: a tap body having a chamber therein extending through an outer surface of the body; a supply passage in said body extending laterally from said chamber; a valve member slidable in said chamber and extending outwardly of said body through said outer surface and having an outer end; a dispensing passage in said valve member extending inwardly from its outer end then curving smoothly laterally toward said supply passage, said supply passage and all of said dispensing passage being of the same uniform cross section; a control member pivotally carried by said body and linked to said valve member for sliding said valve member in said chamber between a first position wherein said curved portion of said dispensing passage is aligned with said supply passage and a second position wherein said dispensing passage is displaced from said supply passage; said chamber being provided with a circular inwardly extending rib, between said supply passage and said outer surface, surrounding said valve member, a groove around said valve member adjacent the inner end thereof and a sealing ring in said groove sealingly engaging said rib when said valve member is in said second position; and means linking said control member to said valve member and being pivotally connected to said valve member laterally of the center line thereof whereby to tend to tilt said valve member and first lift one side of said sealing ring from said rib.

Claim 4

A tap for dispensing carbonated beverages, comprising: a tap body having a chamber therein extending through an outer surface of the body; a supply passage in said body extending laterally from said chamber; a valve member slidable in said chamber and extending outwardly of said body through said outer surface and having an outer end; a dispensing passage in said valve member extending inwardly from its outer end then curving smoothly laterally toward said supply passage, said supply passage and all of said dispensing passage being of the same uniform cross section; a control member pivotally carried by said body and linked to said valve member for sliding said valve member in said chamber between a first position wherein said curved portion of said dispensing passage is aligned with said supply passage and a second position wherein said dispensing passage is displaced from said supply passage; said chamber being provided with a circular inwardly extending rib, between said supply passage and said outer surface, surrounding said valve member, a groove around said valve member adjacent the inner end thereof and a sealing ring in said groove sealingly engaging said rib when said valve member is in said second position; and means linking said control member to said valve member and being pivotally connected to said valve member laterally of the center line thereof whereby to tend to tilt said valve member and first lift one side of said sealing ring from said rib.
