Abstract
A device for controlling the admission of additional gas, such as exhaust gas, to the induction tube of the engine so that additional gas quantities are admitted to the induction tube only during partial load operation. The device includes an additional gas quantity valve situated within the induction tube. The valve includes, in its various embodiments, structure to assure a high tolerance factor in the engagement of the valve seat and the movable valve member so that wear and temperature effects will not adversely affect the control of the additional gas quantity flow.
