Pressure regulation device for supply system of e.g. ion propulsion engine of geostationary telecommunication satellite, has unit controlling valves to increase energy dissipated by valves when measured temperature is less than threshold

摘要

The device (PRG) has electromagnetic actuator valves (5, 6) and a relaxation unit (7) arranged between a high pressure ionizable gas container (1) and a low pressure container (2). A measuring unit measures temperature at the relaxation unit. A control unit (53) controls the valves to increase energy dissipated by the valves when the temperature is lower than threshold temperature, where the threshold temperature is greater than critical temperature of ionizable gas. An insulating enclosure (102) encloses the valves and the relaxation unit. An independent claim is also included for a method for controlling an electromagnetic actuator valve.
