发明名称 Method and apparatus for controlling a surging flow in a closed conduit
摘要 An apparatus and method for controlling a surging flow in a closed conduit is characterized by a moveable flow restrictor element disposed within the closed conduit and responsive to a control signal to restrict the fluid flow therewithin to a damped flow rate. The control signal is generated by a controller element which responds to first and second signals input thereto. The first signal is representative of the instantaneous fluid flow rate within the closed conduit. The second signal is functionally related to the first signal and representative of the damped flow rate within the conduit.
