Abstract

"ESTATOR PARA UMA BOMBA HELICOIDAL EXCêNTRICA OU UM MOTOR SEM-FIM EXCêNTRICO OPERANDO NO PRINCìPIO MOINEAU". A presente invenção refere-se a um estator para uma bomba helicoidal excêntrica ou um motor sem-fim excêntrico, incluindo um tubo externo que é provido com um forro de borracha ou um material semelhante à borracha e tem um espaço oco ou cavidade, na forma de uma espiral dupla ou múltipla, para acomodar um rotor rígido que é também na forma de uma espiral, por meio disso o estator tem uma espiral a mais do que o motor. De modo a que o estator também permaneça funcional sob condições onde a conexão fixa entre o forro e o tubo externo possa ser destruída, por exemplo, devido às influências químicas ou altas temperaturas, a invenção propõe dispor dois tubos internos que têm aberturas no forro.
