Fast attachment open end direct mount damper and valve actuator
First Claim
1. A damper and valve actuator assembly comprising:
- a housing defining an open ended slot;
a rotatable clamping gear including a clamping device having two opposing members disposed within the open ended slot to attach onto either a damper assembly jackshaft, a valve linkage shaft, or a valve stem, the clamping device being accessible via the open-ended slot;
wherein the two opposing members are configured to move toward one another at an equal rate to attach onto either the damper assembly jackshaft, the valve linkage shaft or the valve stem;
a threaded rod for operating the opposing members of the clamping device toward or away from each other; and
a motor configured to rotate the clamping device within the housing via a gear train meshed with the clamping gear; and
wherein the clamping gear is asymmetrical with an open ended shape that coincides with the shape of the open ended slot, andwherein the housing further includes a rod slot through which a portion of the rod extends externally through the housing, the clamping gear includes a first hole to receive the rod, and the rod is configured to move along the rod slot when the clamping device is rotated by the motor.

Abstract
An actuator assembly includes a housing, and a clamp disposed within the housing. The clamp is configured to attach the actuator assembly to a damper jackshaft or valve stem or valve linkage shaft. The jackshaft is operable to control the position of one or more damper blades. The valve stem and valve linkage shaft control the position of the valve plug. The clamp is accessible via a slotted opening which is unobstructed at one end. A motor is configured to rotate the clamping device within the housing. A control module is coupled to the motor and configured to control the damper or valve actuator assembly. In embodiments, a communications module facilitates communications to and from the damper actuator assembly over a network, and allows both remote monitoring of the damper and remote control of the damper actuator assembly or of the valve and remote control of the valve actuator assembly.
