Abstract

MáQUINAS HIDRAULICAS DE PìSTOM LONGO. Motores/bombas hidráulicos menores e mais leves fornecem eficiência volumétrica extraordinariamente aperfeiçoada com pistões tendo porções de corpo substancialmente tão longas quanto o comprimento axial dos cilindros respectivos em que eles reciprocam. Uma pluralidade de canais de lubrificação respectivos, formados circunferencial e radialmente atravessando as paredes de cada cilindro, cada uma é posicionada para ser quase completamente fechada em todos os momentos pelo corpo cilíndrico axial de cada pistom respectivo durante todo o seu percurso. Cada canal de lubrificação é interconectado, um ao outro , para formar uma passagem de lubrificação simples, contínua inteiramente dentro do bloco cilíndrico e nao conectado tanto pelas passagens de "entrada" de fluido quanto pelas passagens de "saída de fluido, sendo reabastecida somente por um fluxo de fluido mínimo que entra da extremidade da válvula de cada cilindro e passa entre cada parede cilíndrica respectiva de cada cilindro e o corpo cilíndrico axial de cada pistom respectivo. Diversas midalidades são descritas em combinação com várias montagens de sujeição de mola de propensão.
