Additionally,the valve housing 44 includes a snift aperture 96 downstream of the outlet 52,also in proximity with the discharge 82 and inlet 90.Anormally closed sniff control valve 98 is operatively associated with the sniff aperture 96 for controlling depressurization of a filled beverage contamer C.The sniff control valve 98 is attached to the lower body section 50 and also has a protruding push button which is depressed by a cam (not shown) supported on the cam rail 76 after completing the fill cycle.When the sniff control valve 98 is depressed,the pressurized gas in the neck of the beverage container C is discharged,returning the interior of the beverage container C to atmospheric pressure prior to separation from the centering bell 53.
A vent stem and valve assembly,generally indicated at 100 in FIGS.2-4,is linearly slidably disposed in the valve housing 44 for selective reciprocating movement between a closed position (FIG.3) sealing the outlet 52 and a fill position (FIG.4) for passing liquid beverage B through the outlet 52 to a beverage container C.Preferably,only one valve assembly 100 is located in each valve housing 44 and serves only one beverage container C at a time.The valve assembly 100 includes an elongated stem 102 oriented vertically and slidably disposed within both the vent 60 and liquid 54 chambers by the stem bushing 62.The stem 102 is hollow and forms a bypass through the liquid chamber 54 for venting pressurized gas from the beverage container C to the vent chamber 60 during the filling operation.
