The process of cosmic ray acceleration in the turbulent medium is studied. It is supposed that charged particles are obtaining the energy in a limited space region and are leaving the acceleration region as a result of spatial diffusion induced by cosmic ray scattering in turbulent magnetic fields. Analytical solutions of cosmic ray transport equation are obtained and equilibrium spatial-energetic distributions of high-energy particles in and outside the acceleration region are investigated.
