Abstract
"êMBOLO REFRIGERADO PARA UM MOTOR DE COMBUSTãO INTERNA". Em um êmbolo refrigerado (1) para um motor de combustão interna, com um canal de refrigeração (2) circulando em forma de anel na altura da parte anelar, que em sua extremidade aberta para a haste do êmbolo está fechado por uma parte elástica (8) correspondentemente moldada e no lado de periferia dividida ao menos uma vez radialmente, provida de entrada de óleo de refrigeração (5), uma melhor derivação de calor em função do local das partes especialmente quentes do êmbolo (1) é obtida pelo fato de que no canal de refrigeração (2) está disposto um anel distribuidor de óleo (3) circulante, que divide o canal de refrigeração (2) no lado da periferia simetricamente da entrada de óleo de refrigeração (5) para a saída de óleo de refrigeração (6) em segmentos (4) de distintos volumes de canal de refrigeração.
