Abstract

"CONJUNTO DE CABEçOTE DE PISTãO PARA MOVIMENTO ALTERNATIVO EM UM CILINDRO, E, PROCESSO PARA FABRICAçãO DE UM CONJUNTO DE CABEçOTE DE PISTãO". Um conjunto do cabeçote de pistão (10), para movimento alternativo em um cilindro (12), uma folga (25) entre o pistão e o cilindro sendo tal que a diferença de diâmetros seja menor do que 0,254 mm. O pistão inclui um flange (11), sobre o qual uma vedação (22), feita de poliuretano, com uma dureza mínima de 80 Shore A, é montada de uma maneira removível. A vedação inclui uma virola (24), que se estende além do diâmetro da parede do cilindro, e uma raiz (23). Uma saliência (23a) é formada na raiz (23), quando a vedação é formada, de maneira a impedir que ligeiras depressões se formem ao redor da raiz, quando a vedação se resfria.
