Abstract
A throttle valve is provided, including a throttle valve body, a valve plug, a hollow seal, a cover, a spring, and a bushing. A flow path is formed in the throttle valve body. The valve plug is disposed in the throttle valve body. The degree of opening of the flow path is modified by rotating the valve plug. The hollow seal is disposed in the throttle valve body. The hollow seal abuts the valve plug. The cover is connected to the throttle valve body. An outlet is formed on the cover, the cover comprises a cover flange, and the cover flange surrounds the outlet. The spring abuts the cover flange to apply an elastic force to the hollow seal for tightly contacting the hollow seal with the valve plug. The spring is telescoped on the bushing, and a first end of the bushing pushes the hollow seal.
