Abstract:
Apparatus (104) for dispensing material produced by a chemical reaction between a first chemical reagent and a second chemical reagent. The apparatus comprises injection means (306) configured to produce a jet of the first chemical reagent and a jet of the second chemical reagent such that the jets collide to produce the material. The apparatus further comprises a storage chamber (317) and a closing device (321). The storage chamber is arranged to provide temporary storage space for the material, and it has an inlet for receiving said material and an outlet (319) for dispensing the material. The closing device is moveable between a first position in which the material is prevented from passing through the outlet of the storage chamber, while allowing material to be received into the storage chamber through the inlet, and a second position in which the material is allowed to be dispensed through said outlet.
Abstract:
Vorrichtung zum Herstellen eines Mehrkomponentengemisches, mit einer von einer Kammerwandung (18) umgebenden Mischkammer (16), die einen Auslass (14) für das Mehrkomponentengemisch aufweist und in die wenigstens zwei Komponentenventile (15) und mindestens ein Spülventil (24) einmünden. Um auf besonders effektive und platzsparende Weise eine Temperierung, insbesondere Kühlung der Vorrichtung unter Ausnutzung von für die Rückspülung der Mischkammer vorgesehenen Wasserleitungen zu ermöglichen, ist erfindungsgemäß vorgesehen, dass das Spülventil (24) einlassseitig mit einem der Kammerwandung zugeordneten, von Wasser durchströmbaren Temperierkanalsystem (19) in Verbindung ist.
Abstract:
The present invention relates to a supply line, a foaming head and a spray head for A) a spraying device comprising - a binder solution supply device and a gas supply device by means of which a fluid binder solution and a gaseous fluid, respectively, are supplied under pressure to a mixing chamber, - a mixing chamber having a first inlet opening and a second inlet opening to which the binder solution supply line and the gas supply line, respectively, are connected, - a hose being communicatively connected to the mixing chamber, which hose opens into a mixing housing of a spray head, - a supply device for coating material, and - a horn comprising a spray nozzle of the spray head, which horn is communicatively connected to the mixing housing; and B) a method for applying a coating layer to a surface, using such a device.
