Abstract

BOCAL PULVERIZADOR PARA ÊMBOLO. A presente invenção refere-se a um bocal pulverizador para êmbolo (12, 112) para a refrigeração de um êmbolo (10) de um motor de combustão interna por meio de um jato de líquido (20, 120) que é dirigido para uma câmara de refrigeração (14) do êmbolo (10). De acordo com a presente invenção é previsto que no centro da abertura de saída (15, 115) do bocal pulverizador para êmbolo (12, 112) é disposto um corpo (16, 116) com uma seção transversal circular que dá ao jato de líquido (20, 120) que sai uma forma essencialmente tubular. O bocal pulverizador para êmbolo de acordo com a presente invenção produz um jato de liquido em feixe, laminar cuja forma fica em alto grau mantida até o encontro com a superfície de refrigeração (14).
