Abstract

"ESTATOR PARA UMA BOMBA ESPIRAL EXCêNTRICA OU UM MOTOR HELICOIDAL EXCêNTRICO QUE OPERA NO PRINCìPIO DE MOINEAU". A invenção refere-se a um estator para uma bomba espiral excêntrica ou um motor helicoidal excêntrico apresentando um estator, que inclui um tubo externo que é provido com um revestimento de borracha ou um material similar à borracha e que apresenta um espaço oco, na forma de uma espiral dupla ou múltipla, para acomodar um rotor rígido que se apresenta também na forma de uma espiral, por meio do que a espiral do estator apresenta uma espiral a mais do que o motor. Para prover um estator que também permaneça funcional sob condições onde a conexão fixa entre o revestimento e o tubo externo seria destruída, por exemplo, devido a influências químicas ou a altas temperaturas, a invenção propõe que um tubo interno provido com aberturas seja disposto no revestimento, e que tiras de espaçamento sejam dispostas entre o tubo externo e o tubo interno.
