Claims
- 1. A beverage filling machine for containers of carbonated beverage comprising a plurality of fill stations where individual containers are filled with carbonated beverage from a supply of beverage at a first predetermined pressure, each fill station having a valve associated therewith and being operable to connect a container at said associated fill station to said supply of beverage, said valves each being provided with a rotor journaled for rotation within a valve chamber maintained at a second predetermined pressure, between a plurality of selected positions to control the filling of said containers, and drive means responsive to eccentric loads applied thereto for causing rotation of said rotor to said selected positions, said drive means including a shaft extending from said chamber through said rotor and being journaled in spaced bearings with one bearing on each side of said rotor, thereby isolating said rotor from said eccentric loads.
- 2. A beverage filling machine for containers of beverage comprising a plurality of fill stations where individual containers are filled with carbonated beverage from a supply of carbonated beverage at a first predetermined pressure, a valve associated with each fill station operable to connect a container at said associated fill station to said supply of beverage, said valve providing housing means defining a closed chamber maintained at a second predetermined pressure approaching said first predetermined pressure, said valves further being provided with a rotor journaled for rotation within said chamber between a plurality of selected positions to control the filling of said containers, said rotor being supported in said chamber by a shaft extending from said chamber, through said rotor and into said housing means and being journaled in spaced bearings with one bearing on each side of said rotor, said second predetermined pressure within said chamber causing a reduction in the differential pressure, with respect to said first predetermined pressure, thereby reducing the tendency for said valve to leak.
- 3. A beverage filling machine as set forth in claim 2, wherein said second predetermined pressure is higher than said first predetermined pressure, and therefore, reduces the tendency for said beverage to leak into said chamber.
- 4. A beverage filling machine as set forth in claim 2, wherein a drain is provided to drain beverage from said chamber without contaminating adjacent portions of said machine.
