Abstract
A barrel throttle valve assembly (20) for use in an air intake system of an internal combustion engine. The barrel throttle valve assembly (20) includes a barrel (32) mounted within a housing (22), with the barrel (32) preferably including an upstream orifice (42), and idle notch (44) and a downstream orifice (46) for controlling the flow of idle air through the valve when the barrel (32) is in a substantially closed position, thus increasing the sensitivity of the valve at idle conditions. Also, preferably, a seal (48) and spring (54) is employed to reduce air leakage around the barrel (32).
