Abstract
Pompe à engrenage destinée à disperser un gaz dans un liquide au moyen, notamment, d'un dispositif de mélange améliorant l'uniformité de la dispersion. Ce dispositif de mélange comprend plusieurs trous borgnes, fixes et peu profonds, débouchant dans la chambre de pompage, entre les orifices d'admission et de sortie du liquide, de manière à être << balayés >> par les dents des pignons lorsque ces derniers tournent. La mise en communication intermittente des trous avec les espaces interdentaires des pignons provoque une turbulence du mélange de gaz et de liquide contenu dans lesdits espaces interdentaires, ce qui améliore l'uniformité de la dispersion du gaz dans le liquide. Domaine d'application : production de mousse d'adhésif fondant à la chaleur.
