ABSTRACT:
A flow control device for controlling the flow rate of fluid utilizes a stepping motor. A translating mechanism translates the rotation of the stepping motor into a rectilinear movement which causes a valve to move in either forward or backward direction, thereby controlling a clearance formed between the valve and its associated valve seat. A channel area is controlled in this manner, and a flow control over an extensive range from a minimal to maximal flow is achieved with a high accuracy and improved response.
