We study a new minimal scalar-tensor model of gravity with Brans-Dicke factor \(\omega(\Phi)\equiv 0\) and cosmological factor \(\Pi(\Phi)\). The constraints on \(\Pi(\Phi)\) from known gravitational experiments are derived. We show that almost any time evolution of the scale factor in a homogeneous isotropic Universe can be obtained via properly chosen \(\Pi(\Phi)\) and discuss the general properties of models of this type.
