Abstract
An actuator assembly includes an actuator and an actuator housing. The actuator includes a main body portion and an actuator shaft. The actuator housing encloses the main body portion of the actuator. The actuator housing includes an outer layer, an inner ceramic fiber layer, an interior chamber that is bounded by the inner ceramic fiber layer, one or more inflow vents for receiving a first fluid, and one or more outflow vents for discharging the first fluid from the actuator housing.
Claims20
An actuator assembly comprising:
- an actuator including a main body portion and an actuator shaft;
- and
- an actuator housing that encloses the main body portion of the actuator, the actuator housing including:
- an outer layer;
- an inner ceramic fiber layer;
- an interior chamber that is bounded by the inner ceramic fiber layer;
- one or more inflow vents for receiving a first fluid;
- and
- one or more outflow vents for discharging the first fluid from the actuator housing.
A valve actuation system, the valve actuation system comprising:
- a valve arranged in a fluid flow path, the valve being movable between an open position and a closed position;
- an actuator including:
- a main body portion;
- and
- an actuator shaft that is coupled to the valve such that the actuator is configured to move the valve between the open position and the closed position;
- and
- an actuator housing that encloses the main body portion of the actuator, the actuator housing including:
- an outer layer;
- an inner ceramic fiber layer;
- an interior chamber that is bounded by the inner ceramic fiber layer;
- one or more inflow vents for receiving a first fluid;
- and
- one or more outflow vents for discharging the first fluid from the actuator housing.
A method of thermally insulating an electric actuator, the method comprising:
- constructing an actuator housing, the actuator housing including:
- an outer layer;
- an inner ceramic fiber layer;
- an interior chamber that is bounded by the inner ceramic fiber layer;
- one or more inflow vents for receiving a first fluid;
- and
- one or more outflow vents for discharging the first fluid from the actuator housing;
- enclosing a main body portion of the electric actuator within the actuator housing;
- and
- connecting the actuator housing to a valve housing.
