Abstract
Patente de Invenção: <B>''ROTORES DE PARAFUSOS GEMINADOS PARA A COLOCAçãO EM MáQUINAS DE DESLOCAMENTO PARA MEIOS COMPRESSìVEIS''<D>. Nas execuções conhecidas de máquinas de deslocamento para meios compressíveis, rotores de parafusos geminados com uma entrada, com passo diminuindo continuamente, trabalham para a obtenção de uma compressão interna. Em alguns casos, este efeito é reforçado ou substituído mediante variação dos perfis de frente. A exigência por bombas compactas com rotores tão curtos quanto possível, assim como a freq³ente exigência devido ao processo por uma desmontagem rápida da caixa para fins de limpeza, no entanto põe limites para os ângulos de enrolamento e para a variação dos perfis de frente, respectivamente, o que por sua vez leva a condições de passo extremas ou a taxas de compressão insuficientes. A presente invenção soluciona estes problemas através de utilização de rotores de parafusos (2) com decurso do passo (<30>W~ 1~, <30>W~ 3~) otimizado, não monótono, e variação do perfil de frente facultativa com diâmetros constantes. Com a mesma necessidade de espaço, a capacidade de sucção é melhorada, e com somente quatro enrolamentos obtêm-se facilmente taxas de compressão de 3,0 e mais. Máquinas de deslocamento equipadas com rotores de parafuso geminados deste gênero oferecem condições ótimas referente à necessidade de energia, temperatura, espaço de construção, serviço com possibilidade de utilização na química e na técnica de semicondutores.
