Device for controlling an amount of exhaust gas returned to an aspirating line

摘要

A device for controlling the amounts of returned exhaust gas, wherein an exhaust gas return valve in an exhaust gas return line is supplied with pressure from a pressure source via a control valve in such a way that the return of exhaust gas is stopped during full load operation and idle operation and is allowed during partial load operations. In this case the control valve is embodied as a 3/3-way valve which, when a fuel injection floating lever is displaced, is continuously displaced in one movement direction and controls the connection between the pneumatic servo motor and the pressure source as a function of the three switching positions of the control valve.
