Abstract

Pompe à liquide comportant une vis sans fin en matériau inflexible entraînée rotativement, un blindage non rotatif matériau flexible entourant la vis sans fin et pourvu d'un taraudage, où le nombre de spires du pas de la vis sans fin et le nombre de spires du taraudage du blindage ont un rapport entre eux de 1 à 2. Le filetage de la vis sans fin et le taraudage du blindage sont conçus coniquement vers le côté de refoulement de la pompe et la vis sans fin ainsi que le blindage sont axialement réglables entre eux. La pompe peut être utilisée pour l'application de plâtre.Liquid pump comprising an endless screw of inflexible material driven in rotation, a non-rotating shielding flexible material surrounding the endless screw and provided with a tapping, where the number of turns of the pitch of the endless screw and the number of turns of the The shield thread have a ratio of 1 to 2. The worm screw thread and the shield thread are designed conically towards the discharge side of the pump and the worm and the shield are axially adjustable between them . The pump can be used for plaster application.
