1. A dosing device for generating a gas flow with a finely dispersed active substance in said gas flow as a result of a negative pressure applied to a mouthpiece of the dosing device, said dosing device comprising a first gas flow channel and a dosing chamber, which is situated at least sometimes in the region of the first gas flow channel, as well as a dosing chamber release mechanism which has a separating element which can be displaced between a closed position and an open position, wherein, in the closed position of the separating element, the separating element seals off the dosing chamber, where in the closed position, the first gas flow channel and/or a connection between the first gas flow channel and the dosing chamber is blocked and, in the open position of the separating element, the separating element no longer seals off the dosing chamber, where in the open position, the first gas flow channel and/or the connection between the first gas flow channel and the dosing chamber is released, and further comprising a slide guide element wherein the separating element or the slide guide element is provided at least in the sliding contact region with a slide element that influences the sliding friction properties.
