Abstract

a presente invenção refere-se a uma bomba de anel líquido que inclui um alojamento estacionário definindo um espaço interno e um eixo de acionamento montado de modo giratório dentro do alojamento estacionário. o eixo de acionamento define um eixo geométrico rotacional. um impulsor (rotor) inclui uma pluralidade de pás se estendendo radialmente para frente em relação ao eixo geométrico rotacional, e cada pá inclui uma base e uma ponta, de modo que uma curva contínua se estende a partir da ponta de cada pá ao longo da base da pá e cruza o eixo geométrico rotacional.
