Abstract

Patente de Invenção: "SISTEMA HIDRáULICO DE TRANSMISSãO DE CURSO". Em um sistema hidráulico de transmissão de curso, particularmente para um bico de injeção de um sistema de injeção de combustível, com um corpo básico (10), um êmbolo de entrada (24), uma cavidade de ligação (38) preenchida com um fluido hidráulico e um êmbolo de saída (14), é assegurado por um lado, uma ventilação da cavidade de ligação e pelo outro, uma transmissão livre de perdas de um movimento do êmbolo de entrada para um movimento do êmbolo de saída. Para esta finalidade, está previsto um êmbolo intermediário (20) deslocável entre uma posição de repouso, na qual a cavidade de ligação está aberta para fora através de uma abertura de ventilação (40), e uma posição de trabalho, na qual a abertura de ventilação e assim a cavidade de ligação estão fechadas.
