Abstract
A priming valve device for a beverage machine. The device includes a casing assembly including a water inlet, a water outlet, and a drain and venting portion for discharging water or air during priming and a valve assembly associated with the casing assembly. The valve assembly includes a valve member which is moveable to a closed position which closes the water outlet by elastic return when the pressure in the water inlet decreases under the elastic return pressure of the valve member.
