<p>A fluid distribution and control valve for respiratory gas delivery systems. The valve has a body which is defined by four internal zones. Each zone is connectable to an external fluid circuit and a mobile structure. The mobile structure can move into four positions. The different positions of the mobile structure determine which of the zones are in fluid communication with each other. The valve may also be used to in a pilot's mask to supply oxygen to the pilot from a main source or from a secondary source.</p>
