摘要：Exhaust gas recirculation valves of this type are needed for exhaust gaspurification for diesel engines used in motor vehicles. These are produced in very largequantities (mass-produced items) so that there is an increased need for advancedsolutions for economic production. For technically simple adjustment of the freeclamping length of the spring, therefore the new exhaust gas recirculation valve ischaracterised in that a cover defining the evacuated chamber has a dome-shapedprojection accommodating the spring, which projection can be pressed into the cover byaxial loading for adjustment of the free clamping length of the spring.
