Abstract

"PINO DE PISTãO PARA MOTOR DE COMBUSTãO INTERNA". Caracterizado pelo fato de que, em um motor de pistão, o jogo ou deslocamento do pino do pistão pode ser evitado sem um encurtamento indevido do pino. No projeto mais simples (figura 4) um pino de pistão com comprimento integral pode possuir uma superfície esférica na extremidade com espaçamento de intervalo próximo com relação à superfície da câmara de combustão, de forma que qualquer tendência do pistão para se deslocar ao longo do eixo do pino é sofre uma imediata reação pelo contato entre uma superfície esférica da extremidade e a superfície da câmara de combustão. A área de cada superfície esférica é suficiente para evitar desgaste ou arranhadura da superfície da câmara de combustão. Um projeto alternativo de pino de pistão de comprimento integral incorpora coberturas ou capas esféricas de chapa metálica posicionadas no local das extremidades (figura 2) as quais fixam o pino (e as coberturas) evitando que entrem em contato com a parede do orifício do cilindro.
