Abstract

resumo patente de invenção: "pistão". a presente invenção refere-se a um pistão (1) para um motor de combustão interna com furos de pino para recepção de um pino de pistão, sendo que os furos de pino (2) estão formados de modo transversalmente oval ao eixo longitudinal do pistão (1). é essencial para a invenção que os furos de pino (2) em ?=0? (zênite) e em ?=180? (nadir) estejam formados cilindricamente com base circular e em ?=90 e ?=270? (equador), de modo oval, com um volume de retenção de óleo, sendo que uma transição entre o equador e o zênite ou entre o equador e o nadir estende-se continuamente e de modo diferenciável, isto é, sem cantos. desse modo, pode ser produzido um pistão (1) de modo eficiente em custos, com boa capacidade de carga e bem lubrificado.
