[en] On an example of calculating vector and pseudovector mass spectra self-consistency of the superconductive quark model (the quark loop model) is proved. By fixing the mass difference of u, s-quarks and u, d-quarks from the mass difference of rho-, phi-mesons and decay ω → π⁺π^- width it is possible to describe correctly both the vector and pseudovector meson mass spectrum, as well as such a subtle effect as the mass difference of K⁰- and K⁺-mesons. Besides, a correct value is found for the difference of decay constants of π- and K-mesons (Fsub(π) and Fsub(K))
