T-slot throttle body shaft

摘要

A throttle body (10) for use with an air intake system of an internal combustion engine. The throttle body (10) includes a throttle valve (18), which includes a throttle plate (20) mounted to a throttle shaft (22) within a slot (26). The throttle shaft also includes a notch (32) extending between the slot (26) and the surface of the throttle shaft (22). The notch (32) allows for ease of manufacturing and assembly and also allows for a slight increase in air flow past the throttle valve with minimal reduction in bending strength of the shaft.
