Inverse systems of R-closed spaces

In the present paper it is proved that a limit of an inverse system of non-empty R-closed spaces and closed irreducible bonding mappings is a non-empty space. If X = {;X_a, f_ab, A}; is an inverse system of R-closed spaces X_a with open-closed mappings f_ab then limX is R-closed.
