Abstract
Patente de Invenção: "êMBOLO REFRIGERADO PARA MOTORES DE COMBUSTãO INTERNA". Com o intuito de obter um melhoramento da dissipação do calor no caso de um êmbolo para motores de combustão interna, com um canal de refrigeração (2) circundante em forma de anel na cabeça do êmbolo (1), o qual, em sua extremidade aberta em direção do fuste do êmbolo, é fechado por meio de uma parte de parede (3), formada de maneira correspondente e dividida pelo menos uma vez de maneira radial, a parte de parede (3) deve ser provida com várias paredes transversais (6), dispostas de maneira aproximadamente radial, distribuídas ao longo de sua circunferência, as quais se estendem de maneira axial para dentro do canal de refrigeração (2).
