Abstract

MÁQUINAS HIDRÁULICAS. Uma máquina hidráulica (1) é provida de uma pluralidade de pás estacionárias (10) alinhadas em uma direção circunferencial, e uma pá guia girável (20) arranjada sobre o lado interno de cada pá estacionária (10. Um nodo de saída (11) de cada pá estacionária (10) é tangente a um círculo de referência compartilhado (12). Cada pá guia (20) inclui uma superfície de pá do lado da pressão (21) e uma superfície de pá do lado da pressão negativa (22), e tem uma linha de curvatura (25) unindo os centros de círculos inscritos (24) tangente a ambas as superfícies de pás, Quando cada pá guia (2) está em um grau máximo de abertura, um ponto central (O) de um maior círculo inscrito (24m) tendo o maior diâmetro dos círculos inscritos (24) da pá guia (20) é posicionado sobre o lado de saída da pá guia (20) a partir de um ponto de interseção (32) entre a linha de curvatura (25) e uma linha reta constituindo de distância mais curta entre o nodo de saída (11) da pá estacionária (10) e a superfície de pá do lado da pressão negativa (22) da correspondente pá guia (20).
