In a valve assembly receivable in an outwardly projecting neck in a keg, for normally sealing the keg and for cooperation with a detachable coupler by which the keg is tapped, the cylindrical spring retainer of the assembly has at its axially inner end deflector surfaces so liquid flowing inward along that cylindrical wall during filling of the keg through the gas passage of the valve assembly is deflected radially across the inner end edge of that wall as a sheet-like jet. This prevents upward spray out of the annular space between the siphon tube and the spring retainer, thus preventing overcarbonation, excessive foaming and underfilling of the keg.
