Abstract
Throttles () include a bore () defined within throttle body (). A longitudinal axis defined within the bore serves as a throttle air flow channel. Throttle shaft () extends across the air flow channel and is rotatably supported by the throttle body about a rotational axis. Throttle valve () is coupled to the throttle shaft and opens and closes the air flow channel by rotating throttle shaft and throttle valve within the bore. The throttle valve extends perpendicularly to the longitudinal axis of the bore when the throttle valve is disposed in a fully closed position. Clearance (S) is defined between a peripheral edge () of throttle valve and an inner wall of the bore when the throttle valve is in the fully closed position. The peripheral edge of the throttle valve end defines a substantially spherical surface having a radius (R) of curvature with respect to the rotational axis.
