Abstract
A throttle flap construction (12) is installed in an exhaust gas duct (11). For the installation the duct wall is provided with a radially facing, axially extending narrow slot (20) centrally provided with a circular opening so that a flap disk (14) may pass radially inwardly through the slot while a bearing portion (17) of the flap disk (14) may pass through the central circular opening. During installation, the flap disk (14) extends vertically when the throttle unit is inserted, a cover (16) is bolted to a flange (11A) surrounding the slot (20) and the central opening (21). Thus, the duct (11) can be properly sealed without cutting entirely through the duct in a radial plane.
