Abstract
A throttle assembly for an internal combustion engine includes a throttle body that defines an airflow passage, a throttle shaft rotatably mounted to the throttle body and extending though the airflow passage, a throttle plate coupled to the throttle shaft, and a seal member coupled to the throttle shaft. More specifically, one end of the throttle shaft extends through the throttle body, and a seal member surrounds the throttle shaft between the throttle body and the shaft. The seal member extending into the airflow passage and effectively forms a standpipe extending into the airflow passage for a length sufficient to prevent pooled engine fluid from seeping out of said throttle body along said throttle shaft.
