A throttle includes a throttle body having a generally tubular throttle body side wall with a throttle body side wall interior surface defining a throttle body interior for containing an air flow path for delivering air into at least one cylinder of an engine; and a flow regulating mechanism including an diaphragm valve secured to the throttle body and extending diametrically across the throttle body interior for progressively reducing and progressively increasing the diameter of an air flow passing valve opening defined within the diaphragm valve, and thereby regulating air flow through the throttle body. |
