Beschreibung
Zusammenfassung:	Valve designed for large flow rates and high pressures, and a rocket engine comprising such a valve, the valve comprising a valve body (11), having a first path (I) and a second path (II), a movable shut-off member (40) configured to adjust the flow cross section between the first path (I) and the second path (II), and an electrical actuator (50) configured to adjust the position of the shut-off member (40), wherein the shut-off member (40) is able to move linearly between a first position and a second position, wherein the actuator (50) comprises a rotor (51) installed in a service cavity (15) of the valve body (11), the service cavity (15) being in fluidic communication with the first path (I) or the second path (II), and wherein the actuator (50) is configured to move the shut-off member (40) via a rotary-linear transmission member (60).
