Valve for a rocket engine

A valve, comprising a valve body, including a first fluidway and a second fluidway,

• a movable shutter, configured to adjust a flow area between the first fluidway and the second fluidway,
• two seals, a first seal being mounted in the second fluidway, ahead of a point of confluence between the first fluidway and the second fluidway, and a second seal being mounted in the second fluidway, behind the point of confluence between the first fluidway and the second fluidway, and
• an actuator, of electrical type, configured to adjust a position of the movable shutter,
• wherein the movable shutter is able to move linearly between a first position, in which it is completely inserted between the first fluidway and the second fluidway, bringing the flow area between the first fluidway and the second fluidway to zero, and a second position, in which the flow area between the first fluidway and the second fluidway is brought to a maximum value,
• wherein the actuator comprises a rotor installed in a service cavity of the valve body, said service cavity being in fluid communication with the first fluidway or the second fluidway, and
• wherein the actuator is configured to drive movement of the movable shutter by way of a rotary-to-linear transmission member.
