FLOW CONTROLLER

摘要

A flow controller is provided. The controller includes a shell body, a first supporting member, a driving shaft and an elliptical valve. The shell body has a passage passed therethrough. The first supporting member is assembled to the shell body. The driving shaft is assembled to the first supporting member. The elliptical valve is pivotally assembled in the passage and is connected with the driving shaft. The elliptical valve is rotated by the driving shaft for opening or closing the passage. When the passage is closed by the elliptical valve, the elliptical valve tightly abuts against an inner circular wall of the shell body for completely closing the passage, so that the controller is suitable in a high temperature and high pressure environment.
