Automotive air inlet flap adjusted by eccentric transfer of force in automotive combustion engine

摘要

An adjustment mechanism for the air valve flap in an automotive combustion engine, has a low pressure chamber (20) whose power output point describes a circle in response to the suction pressure applied. This circular motion is transferred to a cross-member (15) linked to the valve flap (11) lever. The arrangement effects an eccentric transfer of force from the low pressure chamber and is integrated with a membrane operated unit.
