Abstract (en)
[origin: WO2011067138A1] The invention relates to valve devices having a drive unit (16), a gearbox unit (26), an eccentric shaft (37) that can be driven by means of the gearbox unit (26), and a valve rod (68) that is displaceable in translation, to which a coupling element (66) is fastened, by means of which the displacement of the eccentric shaft (37) can be converted into a translational displacement of the valve rod (68). The gearbox unit for the known valve devices tends to become contaminated by blow-by gases. According to the invention, a cover (52) is disposed between the eccentric shaft (37) and the coupling element (66), separating the gearbox chamber (28) from the valve rod displacement chamber (54).
