SYSTEME DE COMMANDE D'UNE VALVE A TIROIR A DEBIT CONTROLE

摘要

The slide valve control system has an energy feed source and security means for valve closure and opening with an emergency reservoir and selective connection of the reservoir to the valve control motor. The emergence energy reservoir (C) is loaded from a charge pump carrying an inductance (L). The reservoir circuit is loaded from the inductance energy freed whilst the excitation current is cut.
