Abstract
Based on 123 high-resolution CCD spectra carried out in 40 nights and previ ously published data, a refined period P = 21.6878 +/- 0.0001d and a new or bit solution for the Wolf-Rayet star HD 193928 were obtained. In light of t he newly derived mass function of the system, and taking into consideration the recent results of Marchenko et al. (1998a), the probable spectral clas s and minimum mass of the companion are briefly discussed.
