Air valve device having flush closing nozzle

In an air valve including a tubular valve body presenting an input end and an output end, means supporting said valve body for selective movement thereof in order to vary the direction of air output from said output end, a shiftable valve member located at least partially within said body and being selectively movable between a valve closed position blocking air flow through the body, and a valve open position permitting air flow through the body, the improvement comprising:

• said valve body output end including structure defining an outer wall, a planar, annular end wall transverse to said outer wall, and an inner wall located radially inward of said outer wall and adjacent said end wall, a part of said inner wall defining a sealing surface;
• and
• said valve member being supported for shiftable movement relative to said valve body and including an elongated shank having a sealing surface that seats against the valve body sealing surface in the valve-closing position of the valve members, the shank including a planar end surface disposed parallel to said valve body end wall,
• said end surface being coplanar with the valve body end wall and presenting a substantially continuous flat surface when said valve member sealing surface is seated against the valve body sealing surface.
