Abstract

Patente de Invenção: <B>BOMBA PERISTáLTICA''<D>. Bomba peristáltica para propelir líquido, através de um segmento de tubo flexível. A bomba possui um eixo de came suportando uma pluralidade de cames, cada um possuindo uma superfície de acionamento. Estas superfícies de acionamento, de cames adjacentes estando espaçadas de maneira reciprocamente angulada, em torno do eixo de came. A bomba possui ainda uma pluralidade de seguidores de came, os quais são recíprocos em uma direção comum, perpendicular ao eixo do eixo de came. Cada seguidor de came possui uma superfície montada sobre a superfície de acionamento do came e uma superfície de engate de tubo, para engatar o segmento de tubo flexível. Pelo menos um dos seguidores de came é um seguidor de came de restrição, do qual a superfície de engate de tubo engata o segmento de tubo flexível por um período de tempo mais longo do que o de outros cames. A bomba também possui um motor para rotação do eixo de came, através do qual os cames fazem com que os seguidores de came de cada engatem e obstruam o segmento de tubo flexível, a fim de formar uma onda de propagação depressiva no segmento de tubo flexível para propelir líquido. Os seguidores de came de restrição impedindo o refluxo do líquido.
