Gate valve assembly for controlling recirculated exhaust gas flow in e.g. intake manifold of internal combustion engine, has transmission elements positively driven over guide contours of forming device in closing and opening directions

摘要

The assembly has two translative movable valve closures (10, 12) connected with respective motion transmission elements (14, 16), where through-openings (2, 4) are closeable or openable by the respective closures. The transmission elements are driven by an electric motor (40), where motion of the motor is transferred to the elements over a kinetic forming device (34). The elements are positively driven over link-shaped guide contours (46, 48) of the forming device in closing and opening directions, where the contours are pivotable along a rotational axle (37) i.e. output shaft (36).
