Abstract

"PULVERIZADOR DE ARREFECIMENTO DE PISTãO". Pulverizador de arrefecimento, de acordo com a invenção, permite o arrefecimento do pistão de um motor à combustão interna. O pulverizador compreende um corpo de pulverizador (1) de parte penetrante conformada para se encaixar em uma perfuração do motor e para receber o fluido de arrefecimento. O pulverizador compreende uma válvula interna constituída de um pistão (6) orientado com deslizamento em uma perfuração de orientação (9) do corpo de pulverizador (1). O pistão (6) comporta uma cabeça de obturação (10) orientada para cima e vindo se colocar contra uma sede anular de obturação (11). O pistão é empurrado em direção à sede anular de obturação (11) por uma mola helicoidal de compressão (13). Fabrica-se assim um pulverizador de arrefecimento com válvula interna que apresenta maior resistência para os circuitos de arrefecimento de motor à alta pressão.
