Abstract
A device for controlling a spacecraft by gating gas, the device comprising a nozzle, a gas feed duct, a gate having a seat and a plunger interposed between the feed duct and the nozzle, and control means for opening and closing the gate in order to put the feed duct selectively into communication with the nozzle. The seat of the gate is secured to the nozzle and the nozzle is movable such that the gate is opened and closed by displacement of the nozzle, which displacement is driven directly by the hot gas, without calling on an auxiliary fluid.
