Abstract
A throttle body comprising a main body defining a cylindrical intake air channel and including a valve member movable between an open and a fully closed position. The valve seal surface and a contact surface are configured such that the valve seal surface sealingly contacts with the corresponding contact surface when a fully closed position of the valve has been displaced due to contraction of one of the main body and the valve member. The valve seal surface and the contact surface of the valve member in the fully closed position are inclined by an angle. The contact angle of inclination gradually decreases from a first point located on a circumference of the periphery of the valve member resulting from a line perpendicular to an intersection of the central axis and the rotation axis to a second point that is proximate to the rotation axis of the valve member.
