An exhaust control valve comprising a valve body defining a fluid flow path through the exhaust control valve. A valve member for controlling fluid flow rate along the fluid flow path is rotatably connected to the valve body. A drive member extends into in the valve body and is provided for moving the valve member relative to the valve body. A mechanical seal is provided for limiting fluid leakage from the fluid flow path out of the valve body along a clearance gap adjacent the drive member.

The present invention relates to a throttle valve adapted to equip an air intake system in an internal combustion engine, in particular an explosion engine. The throttle valve comprises: a body delimiting an air intake pipe; a valve member mounted rotatably in the pipe about an axis of rotation and comprising a spherical portion shutting off the pipe in the closed configuration; means for moving the valve member in rotation about the axis of rotation between different configurations of the throttle valve; and a bearing ring which receives a spherical outer surface of the valve member in sliding bearing contact. The throttle valve is characterized in that it also comprises a seal which is elastically deformable, which is arranged between the body and the bearing ring and which is adapted to take up forces to which the valve member and the bearing ring are subjected during a back-fire through the pipe. The invention also relates to an internal combustion engine, in particular an explosion engine, comprising such a throttle valve.

An intake manifold (100) having variable diameters is provided. The intake manifold (100) includes a tube body (110) and a valve (120) . The valve is rotatably disposed in the tube body (110), wherein the valve (120) is a hollow-ring and comprises an outer circumference (122) and an inner circumference (121), and a gradient curve surface (123) is formed from the outer circumference (122) to the inner circumference (121). The inner circumference (121) defines a inlet face (A2), and a gradually varied angle is formed between a normal vector (T2) of the inlet face (A2) and a cross section (A1) at an end of the tube body (110) while the valve (120) rotates.It is also provided an intake manifold (200) having variable diameters. The intake manifold (200) includes a tube body (210) and a valve (220). The valve is composed of two hollow rings (221, 222), wherein the two hollow rings (221, 222) overlap along a central axis (X) of the tube body (210) and relatively rotate to each other around the central axis (X). Each of the two hollow rings (221, 222) comprise an inner circumference (221a) and an outer circumference (221b), a plurality of air holes (223, 224) having corresponded positions are formed between each of the inner circumference (221a) and each of the outer circumference (221b), and each of the inner circumference (221a) defines a inlet face (B1, B2). When the two hollow rings (221, 222) relatively rotate to a first position, the air holes (223, 224) of the two hollow rings (221, 222) are overlapped and through with each other; when the two hollow rings (221, 222) relatively rotate to a second position, the air holes (223, 224) of the two hollow rings (221, 222) are partially blocked with each other; and when the two hollow rings (221, 222) relatively rotate to a third position, the air holes (223, 224) of the two rings (221, 222) are completely blocked with each other.
