We present a modification of the method for reconstructing the stellar velocity ellipsoid (SVE) in disc galaxies. Our version does not need any parametrization of the velocity dispersion profiles and uses only one assumption that the ratio σ_z/σ_R remains constant along the profile or along several pieces of the profile. The method was tested on two galaxies from the sample of other authors and for the first time applied to three lenticular galaxies NGC 1167, NGC 3245 and NGC 4150, as well as to one Sab galaxy NGC 338. We found that for galaxies with a high inclination (i > 55° - 60°) it is difficult or rather impossible to extract the information about SVE, while for galaxies at an intermediate inclination the procedure of extracting is successful. For NGC 1167 we managed to reconstruct SVE, provided that the value of σ_z/σ_R is piecewise constant. We found σ_z/σ_R = 0.7 for the inner parts of the disc and σ_z/σ_R = 0.3 for the outskirts. We also obtained a rigid constraint on the value of the radial velocity dispersion σ_R for highly inclined galaxies, and tested the result using the asymmetric-drift equation, provided that the gas rotation curve is available.
