Compiled equations describing the experimental data of the liquid-vapor phase equilibrium in binary mixtures of helium with nitrogen, oxygen and argon. Equations represents the dependence of liquid or vapor pressure from temperature and composition. At their compiling selected automaticaly most significant coefficients of equation. Standard deviations of the experimental values of the pressure from calculated are equal from 3,5 to 4,5 %. Equations permits to determine the composition or temperature of phases at known values of  other parameters of the phase equilibrium.
