<p>A bottle filling apparatus (10) is provided in which a non-contact choke valve (62) is employed. The choke valve (62) comprises a disc (58) having an outer cylindrical wall (76) which is received within a valve seat (68) having an inner cylindrical wall (70). The cylindrical walls have a close tolerance fit, preventing flow therebetween by molecular action and surface tension. Additionally, the bottom surface min 78) of the seal (58) and the top surface (80) of the seat (68) have similar tapers such that, with the seat below the seal in a normal dispensing operation, beverage flow is directed into the bottle without turbulence and the resultant foaming action. <IMAGE></p> |
