Abstract
A relatively small, lightweight valve actuator assembly that can withstand relatively high levels of vibration and shock includes a motor, a position sensor, and a drive belt mounted on an actuator housing assembly. The position sensor is preferably disposed within a sensor housing that is mounted on a side of the actuator housing assembly. As a result, the overall center-of-gravity (CG) and weight of the actuator assembly is significantly reduced, as is the overall size envelope.
Claims20
A valve actuator assembly, comprising:
- an actuator housing assembly;
- a motor mounted in the actuator housing assembly, the motor adapted to receive valve position command signals and configured, upon receipt thereof, to supply a drive force;
- a position sensor rotationally mounted in the actuator housing assembly and operable to supply a position signal that is at least representative of a rotational position of the motor;
- and
- a drive belt coupled between the motor and the position sensor and configured to couple the drive force to the position sensor.
A valve actuator assembly, comprising:
- an actuator housing assembly;
- a motor mounted in the actuator housing assembly, the motor adapted to receive valve position command signals and configured, upon receipt thereof, to supply a drive force;
- an actuator output shaft rotationally mounted in the actuator housing assembly, the actuator output shaft coupled to receive the rotational drive force from the motor and configured, upon receipt thereof, to rotate to a rotational position;
- a position sensor rotationally mounted in the actuator housing assembly and operable to supply a position signal that is at least representative of the rotational position of the actuator output shaft;
- and
- a drive belt coupled between the actuator output shaft and the position sensor and configured to couple the drive force to the position sensor.
A valve actuator assembly, comprising:
- an actuator housing assembly having a motor end, an output end, and one or more sidewalls therebetween;
- a motor mounted in the actuator housing assembly proximate the motor end, the motor adapted to receive valve position command signals and configured, upon receipt thereof, to supply a drive force;
- an actuator output shaft rotationally mounted in the actuator housing assembly and extending at least partially from the output end, the actuator output shaft coupled to receive the rotational drive force from the motor and configured, upon receipt thereof, to rotate to a rotational position;
- a position sensor rotationally mounted in the actuator housing assembly proximate one of the sidewalls thereof, the position sensor operable to supply a position signal that is at least representative of the rotational position of the actuator output shaft;
- and
- a drive train coupled between the motor and the position sensor and configured to couple the drive force to the position sensor.
