A spatially flat Friedmann model of the Universe filled with the perfect liquid with a nonlinear homogeneous time-dependent equation of state is discussed. A gravitational equation of motion is solved. It is shown that in this case, there can result a periodic Universe rerunning cycles of space acceleration of the phantom (non-phantom) type with occurrence of cosmological singularities.
