ELECTRONIC EXHAUST GAS RECIRCULATION ACTUATOR FOR INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: An electronic exhaust gas recirculation actuator for an internal combustion engine is provided to simplify a structure by using a spur gear structure when delivering a rotation force from a motor to a valve in order to increase the operation force of the valve. CONSTITUTION: An electronic exhaust gas recirculation actuator for an internal combustion engine comprises a drive unit(10), a gear link(20), a cam body(30), and a valve body. The gear link is comprises a plurality of gear joint structures for amplifying a driving force from the drive unit. The top end of the cam body is connected to the shaft(23) of the gear link in order to be eccentric through an eccentric rotation disk. The cam body is connected to a valve shat(40) for opening and closing a valve in the lower end and is supported by a ball bearing. The cam body converts the amplified driving force into a linear movement for delivering to the valve shaft. The valve body is equipped with an inlet for the intake of exhaust gas to a combustion chamber. The valve body is integrally formed with a valve disk(50) for opening and closing the inlet with the valve shaft.
