Abstract

<B>Patente de Invenção de " "MECANISMO PARA PREVENçãO DE ROTAçãO E APARELHO PARA DESLOCAMENTO DE FLUIDO DO TIPO-ESPIRAL"<D>. Em um mecanismo para prevenção de rotação em que uma esfera (26) é disposta entre um par de pistas (24, 25) cada uma tendo uma superfície de entalhe de rolamento (24c, 25c) recebendo a esfera, a superfície de entalhe de rolamento tem uma porção inferior (24c3, 25c3) de um raio de curvatura que é maior do que cada um daqueles de uma porção periférica externa (24c1, 24c2) e uma porção periférica interna (25c1, 25c2). Cada um dos raios das porções periférica externa e periférica interna é próxima a e maior do que o raio da esfera. As pistas são fixadas a um alojamento frontal (10b) e um elemento espiral móvel (30) que realiza movimento orbital ao longo de uma órbita predeterminada com relação ao alojamento frontal. A superfície de entalhe de rolamento tem um formato anular correspondendo à órbita predeterminada.
