摘要： A process and apparatus are described for the production of a flowable reaction mixture from at least two flowable reactive components which may be difficult to mix, which components react with one another to form a solid or a foam material. The components are injected into a mixing zone where the components are mixed in a continuous flow. The mixture flowing from the throttling zone is divided into two sub-streams which flow around a piston and which recombine opposite the division point.

摘要： In order to keep the reversing times from circulation of the reaction components to mixing and vice versa as short as possible for the purpose of good mixing in the initial and end phases in the preparation of flowable reaction mixtures by high-pressure mixing, the holding pressure applied to the flow reversing element is maintained by a releasable non-return valve until the full hydraulic reversing pressure has built up on the opposite side, and only then is the non-return valve released.

摘要： Hydraulically coupled injection nozzles (5,28) and return nozzles (15,38) are used in an apparatus for producing a reaction mixture of fluid components forming foam or a solid material. These nozzles (5,15,28,38) comprise control pins (11,20,34,43) which are designed to be inserted into the openings (6,17,29,40) of the nozzles (5,15,28,38). The ratio between the distances which the control pins (11,20,34,43) travel outside and inside the orifices (6,17,29,40) is adjusted in such a way that, when the nozzles (5,15,28,38) are switched from "mixing" to "circulation" or vice versa, there is a time interval during which all the nozzles (5,15,28,38) are closed.
