Abstract
A device for regulating pressure and/or mass flow of a gaseous or liquid fluid conveyed through a line in a space propulsion system includes a first, piezoelectrically actuatable regulating valve and at least two second, magnetically actuatable regulating valves. The regulating valves are connected to each other and to a line input in such a way that in a nominal mode the pressure and the mass flow of the fluid can be set by the first regulating valve, and a connection or isolation of the first regulating valve with or from the line input can be produced by the second regulating valves. In an emergency mode the pressure and the mass flow of the fluid can be set by the second regulating valves.
