| 摘要 |
The present invention provides a flow control valve that requires only a relatively small opening/closing drive force, is compact and does not induce a pulsating flow in the valve open state. A valve seat (3) is disposed in a pipeline (5) through which a fluid flows. A spherical valve element (12) assuming a diameter smaller than the inner diameter of the pipeline (5) is housed inside the pipeline (5). A vibrating motor (8), which eccentrically rotates the valve element (12) kept in contact with the inner wall of the pipeline (5) is disposed outside the pipelines (5) and (6).
