FIELD: pneumatic control. SUBSTANCE: jet diode comprises coaxial inlet 1 and receiving 2 tubes. Bell 3 and return flow deviation elements are connected with internal surface of bell 3 and are made in the form of radial longitudinally-passable hollows 4 in internal surface of bell 3. EFFECT: return flow deviating elements do not protrude into the flow which reduces aerodynamic resistance of diode. 2 dwg
