ABSTRACT:
A throttle body for an internal combustion engine has a housing, a first plate carried by the housing for linear reciprocation between a first position and a second position in response to movement of a throttle member, and a second plate carried by the housing for linear reciprocation between a first position and a second position in response to the movement of the fist plate. The first plate and second plates define at least in part an opening through the throttle body. The opening provides a variable flow area that increases as the first plate and the second plate move from their first positions toward their second positions and decreases as the first and second plates move from their second positions toward their first positions. As the first and second plates move between their first and second positions, the flow area of the opening is continually varied.
