Abstract
A valve device (110), in particular a throttle device, preferably for use in motor vehicles, the finished valve device (110) comprising a housing (120), which surrounds a flow duct portion (126, 128, 130, 133), and additionally comprising at least two valves (132, 134, 136, 137) accommodated on the housing (120) and movable relative thereto such that, by relative adjustment of the valves (132, 134, 136, 137) relative to the housing (120), the effective flow area of the flow duct portion (126, 128, 130, 133) may be modified, adjacent valves (132, 134, 136, 137) being produced separately and being couplable or coupled together for joint movement by interlocking geometries (164, 166).
