In this paper I study stationary, spherically symmetric accretion of fluidsonto a charged black hole in the presence of the cosmological constant. Forsome isothermal equations of state it is possible to obtain analytic solutions.In the case of a radiation fluid I point out a connection between locations ofthe horizons and the sonic (critical) points. In specific cases the solutionsform closed, binoculars-like trajectories in a phase diagram of the velocityvs. radius.
