Abstract
An intake manifold having variable diameters is provided. The intake manifold includes a tube body and a valve. The valve is rotatably disposed in the tube body, wherein the valve is a hollow-ring and includes an outer circumference and an inner circumference, and a gradient curve surface is formed from the outer circumference to the inner circumference; wherein the inner circumference defines a inlet face, and a gradually varied angle is formed between a normal vector of the inlet face and a cross section at an end of the tube body while the valve rotates.

An intake manifold having variable diameters, the intake manifold comprising:
- a tube body;
- and
- a valve rotatably disposed in the tube body, wherein the valve is a hollow-ring and comprises an outer circumference and an inner circumference, and a gradient curve surface is formed from the outer circumference to the inner circumference:
- wherein the inner circumference defines a inlet face, and a gradually varied angle is formed between a normal vector of the inlet face and a cross section at an end of the tube body while the valve rotates.
An intake manifold having variable diameters, the intake manifold comprising:
- a tube body;
- and
- a valve composed of two hollow rings, wherein the two hollow rings overlaps along a central axis of the tube body and relatively rotates around the central axis, each of the hollow rings comprises an inner circumference and an outer circumference, a plurality of air holes having corresponded positions are formed between each of the inner circumference and each of the outer circumference, and each of the inner circumference defines a inlet face;
- wherein when the two hollow rings relatively rotate to a first position, the air holes of the two hollow rings are overlapped and through with each other;
- when the two hollow rings relatively rotate to a second position, the air holes of the two hollow rings are partially blocked with each other;
- and when the two hollow rings relatively rotate to a third position, the air holes of the two rings are completely blocked with each other.
