Abstract

resumo patente de invenção: "pistão para motor de combustão". a presente invenção se refere a um pistão (10) para um motor de combustão, com um cabeçote de pistão (11) e uma haste de pistão (12), sendo que o cabeçote do pistão (11) possui um fundo de pistão (13), uma seção anelar (16) circundante, bem como, na região da seção anelar (16), possui um canal de refrigeração fechado circundante ou um compartimento oco (18) fechado, sendo que um lado interno (12) do pistão (10) possui duas faces inferiores (34a, 34b), as quais, na região do eixo central do pistão (m), convergem continuamente em uma face arqueada (35), sendo que a haste do pistão (21) possui cubos de pistão (22), providos de perfurações de cubos (23),os quais, através da faces de deslocamento (24,25) estão interligadas.apresentando faces internas (32a,32b), voltadas na direção do interior do pistão, caracterizado pelo fato de que partindo da livre extremidade da haste do pistão (21), no interior do pistão, no lado da pressão (ds) e/ou no lado contrário da pressão (gds), uma face interna (32a,32b) de uma face de deslocamento (24,25), converge, continuamente, em uma face condutora (33a,33b) para o frigorígeno, a qual, por sua vez, converge, continuamente, em uma face inferior (34a, 34b).
