Patent ID: 7530505

Claim:
A catching nozzle for a powder conveying device, the catching nozzle comprising: an upstream catching nozzle section; a downstream catching nozzle section, the downstream catching nozzle section configured to receive a hose socket of the powder conveying device that is pushed over the downstream catching nozzle section; a shoulder arranged between the upstream catching nozzle section and the downstream catching nozzle section, and a first cylindrical guide surface adjacent the shoulder and arranged in the upstream catching nozzle section, the shoulder and the first cylindrical guide surface for defining a radial position of the catching nozzle in the powder conveying device; a tubular powder flow duct within the upstream nozzle section, downstream nozzle section and shoulder; a duct that passes through the shoulder and the first cylindrical guide surface for connecting dosage air from an exterior of the upstream catching nozzle section to an exterior of the downstream catching nozzle section; and another duct for leading dosage air along the exterior of the downstream catching nozzle section to the downstream end of the catching nozzle.
