Abstract

Das Spritzmischdüsenaggregat, welches sich insbesondere für Beton-Trockenspritzen eignet, ist mit Trockenbeton­ gemischeinlauf und eine um diesen angeordnete Wasserzufuhr vorgesehen. Ein Wasserdüsenring (12), auf welchen, vor­ zugsweise gleichmässig über den Ringumfang, im wesentli­ chen radial verlaufende, zur Ringlängsachse geneigte Wasserdurchgänge (28) angeordnet sind, dient dazu, den Gesamtdüsenquerschnitt (28) für das Wasser unmittelbar vor dessen Zusammentreffen mit dem Betongemisch stetig zu ändern. Bei diesem Spritzmischdüsenaggregat wird bei im wesentlichen gleichbleibender, konstanter Düsenstrahl­ geschwindigkeit die Wassermenge durch Veränderung des Düsenquerschnittes unmittelbar vor dem Wasseraustritt selbst geregelt. Dazu bedient man sich einer sehr einfach zu handhabenden, auf Verdrängerbasis arbeitenden hydrau­ lischen, handbetätigbaren Verstelleinrichtung.
