Abstract

In a device for dosing two-component products of a predetermined mixing ratio, the dispensing accuracy has been improved in conjunction with simple design and uncomplicated operation. According to the invention, two chambers are provided which are put under pressure by means of two pistons that are displaced simultaneously in opposite directions from a starting point. A mixer means is arranged at the closed longitudinal end of a first chamber, while the closed longitudinal end of the other chamber is connected to the mixer means over a component line that leads centrally through the first chamber.
