Abstract

L'invention concerne un dispositif pour doser des produits à deux composants devant être mélangés dans un rapport de mélange prédéterminé. Ce dispositif comprend deux chambres (1 et 2) disposées l'une derrière l'autre dans le sens axial et qui contiennent des tubes (3 et 4) placés de manière concentrique dans lesdites chambres. Ces tubes peuvent coulisser de manière télescopique l'un dans l'autre et comportent au niveau de leurs extrémités avant et arrière, des ouvertures (5 et 6) permettant l'acheminement des composants liquides à l'intérieur des tubes, jusqu'à l'ouverture de prélèvement. Ces dispositifs se présentent de préférence sous forme de cylindres, dont les dimensions extérieures sont choisies de manière qu'un pistolet à cartouche standard puisse être utilisé pour exprimer les produits à deux composants hors de ce dispositif.
