Abstract

"ANEL DE óLEO PARA MOTOR DE COMBUSTãO INTERNA". Compreendendo um corpo anelar (10) a ser montado em torno de um pistão (P) reciprocante no interior de um cilindro (C) do motor, dito corpo anelar (10) apresentando faces extremas opostas (11), uma face interna (12) para assentamento de um expansor elástico (M) e uma face externa de contato (13) assentável contra a face interna do cilindro (C) e apresentando uma altura (h) substancialmente menor do que a altura (H) da face interna (12) . Cada face lateral (11) é definida por uma ou mais porções de face lateral (11a, 11b) configuradas para prover uma redução do momento de inércia do corpo anelar (10), conferindo-lhe melhor conformabilidade. Preferencialmente, mas não exclusivamente, o anel apresenta canais axiais (15, 16) estendidos por pelo menos parte da altura do anel e radialmente recuados em relação à face externa de contato (13).
