Air vent valve for beverage makers

An air vent valve assembly for a tank assembly of a beverage maker for aircraft, comprising:

• a vent valve body having an interior chamber and an outlet flow passage in fluid communication with the interior chamber;
• a valve adapter that sealingly mates with the vent valve body, the valve adapter being adapted to be attached to the tank assembly of the beverage maker, the valve adapter having an interior flow chamber connected in fluid communication with the interior chamber of the vent valve body, and a flow inlet connected in fluid communication with the interior flow chamber of the valve adapter;
• a tubular collar having a lumen disposed within the interior chamber of the vent valve body;
• a planar valve seat member disposed within the interior chamber of the vent valve body between the tubular collar and the outflow passage of the vent valve body, the planar valve seat member having a surface defining a central flow aperture;
• and
• a float valve element movably disposed within the lumen of the tubular collar, the float valve element having a first valve seating position abutting and closing the central flow aperture of the planar valve seat member, and a second unseated position spaced apart from and opening the central flow aperture of the planar valve seat member, and wherein the valve adapter has an interior support surface including a plurality of radially projecting outer flow passages configured to support the float valve element when said float valve element is in said second unseated position and to retain the float valve element within the tubular collar without permitting the float valve element to become stuck in the bottom of the valve adapter when the float valve element is at the bottom of the tubular collar.
