Manner and device null in order conservation the propulsion catalytic converter floor from the degradation with passing the fuel

摘要

Method and device for protecting a catalytic bed (4) from deterioration due to the impurities in a propellant fuel. …??The method consists, by briefly and periodically interrupting the supply of fuel by means of the solenoid valve (1), in creating abrupt pressure oscillations in the injection chamber (3) which expel the impurities in the pasty or possibly solid state towards the nozzle (6). …??Application to space vehicles. …IMAGE…
