Abstract
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.

A flow controller comprising:
- a shell body, having an inner circular wall and an outer circular wall, a passage surrounded by the inner circular wall;
- a first supporting member assembled to the shell body, the first supporting member having an axle hole communicating with the passage;
- a driving shaft pivotally received in the axle hole;
- an elliptical valve pivotally assembled in the passage and connected with the driving shaft, including a baffle plate and a sealing arrangement, the baffle plate being elliptical and having a periphery, the baffle plate having a substantially fixed thickness, the sealing arrangement including a plurality of connectors and an elastic member;
- and
- wherein the elastic member is a Teflon ring member, the connectors are detachably disposed annularly on respective peripheral edges of two corresponding lateral sides of the baffle plate respectively, the to peripheral edges of the baffle plate are sandwiched by the connectors, the connectors and the baffle plate form round hollow portions respectively on the two corresponding lateral sides of the baffle plate, the connectors are protrusive radially out of the baffle plate so that the connectors and the baffle plate form a annular receiving recess circumferentially, the elastic member is disposed annularly within the receiving recess and protrusive radially out of the connectors, the elastic member has a thickness equal to or less than the thickness of the baffle plate;
- wherein the elliptical valve is rotated by the driving shaft for opening or closing the passage.
