The invention relates to a device for mixing fluids and for producing a fluid mixture, including, a mixing chamber having a first inlet opening via which a first fluid can be introduced into the mixing chamber, a second inlet opening via which a second fluid can be introduced into the mixing chamber, and an outlet opening via which the fluid mixture including the first fluid and the second fluid can be discharged; a first supply unit, which is fluidically connected to the mixing chamber via the first inlet opening and is designed to carry the first fluid along a first fluid flow direction into the mixing chamber; and a second supply unit, which is fluidically connected to the mixing chamber via the second inlet opening and is designed to carry the second fluid along a second fluid flow direction into the mixing chamber. The first supply unit includes a fluidic component, including an outlet opening, which is fluidically connected to the first inlet opening of the mixing chamber, and at least one means for specifically changing the direction of the first fluid that flows through the fluidic component, in particular in order to cause an oscillation in space of the fluid at the outlet opening.
