Abstract

CILINDRO COM MEIO PARA RECEBIMENTO DE LUBRIFICANTE. A presente invenção refere-se a um cilindro (1) para um motor a pistão que inclui um meio (5) para o recebimento de lubrificante. O cilindro inclui uma superfície deslizante (7) para um pistão (2), a superfície deslizante apresentando uma zona morta superior (8) e uma fileira de fendas de lavagem (6) disposta no cilindro. Esta superfície deslizante (7) apresenta uma pluralidade de rebaixos na forma de fenda (5), com os rebaixos na forma de fenda apresentando um comprimento (9), uma largura (10) e uma profundidade (11), com a profundidade (11) abrangendo mais de 0,4 mm. Os rebaixos na forma de fenda (5) são providos abaixo de uma região na forma de anel da superfície do cilindro (12) que apresenta um comprimento de até 15% do comprimento (13) da superfície deslizante (7) medido a partir de sua zona morta superior (8).CYLINDER WITH MEDIUM FOR RECEIVING LUBRICANT. The present invention relates to a cylinder (1) for a piston engine including a means (5) for receiving lubricant. The cylinder includes a sliding surface (7) for a piston (2), the sliding surface having an upper dead zone (8) and a row of wash slots (6) disposed on the cylinder. This sliding surface (7) has a plurality of slit-shaped recesses (5), with the slit-shaped recesses having a length (9), a width (10) and a depth (11), with depth (11). ) covering more than 0,4 mm. Slot-shaped recesses (5) are provided below a ring-shaped region of the cylinder surface (12) having a length of up to 15% of the length (13) of the sliding surface (7) measured from its surface. upper dead zone (8).
