Abstract

"ANEL DE SEGMENTO PARA MáQUINAS DE MOVIMENTO ALTERNATIVO". A invenção refere-se a um anel de segmento fendido (1) para êmbolos de motor de combustão interna ou compressores, tendo um rebaixo periférico (9) (um chamado anel recolhedor) que se estende até próximo à fenda (2) na periferia externa (3) do êmbolo oposta à câmara de combustão. O objetivo da invenção é reduzir o consumo de óleo e a quantidade de gás de fuga de tal êmbolo. Para isto, o rebaixo está configurado de modo a estender-se de uma zona (10) diametralmente oposta à fenda, partindo de uma altura máxima (12) que diminui gradualmente até zero (13) na direção da fenda ou próximo à fenda.
