ABSTRACT:
A supercharged engine has a charge air intake and an engine exhaust outlet, a positive displacement supercharger connected to the air intake, a charge air and bypass control valve comprising a rotary body throttle valve including a rotary valve body, a primary air passage and a separate bypass air passage each extending through the rotary body. The primary air passage is fully open in a first rotary position of the rotary body wherein the bypass air passage is closed, and the bypass air passage is fully open in a second rotary position wherein the primary air passage is closed. Airflow through the passages varies in an inverse manner as the rotary body is rotated between the first and second positions, whereby airflow through the control valve is controlled with a single actuator movable through the full range of positions and airflow through the primary and bypass passages is inversely varied.
