Abstract

A novel throttle device adjuster having a U-shaped fastening bracket, connected to a throttle valve shaft and having a sawtooth contour in the region of two locking segments that pass through a pulley in two fastening bracket receptacles; the sawtooth contour, together with the fastening bracket receptacles, produces a firm connection of the pulley to the fastening bracket without further connecting elements. The novel throttle device adjuster is especially suitable for throttle equipment in internal combustion engines of either the mixture-compressing, externally ignited or the air-compressing, self-ignited type. Instead of the sawtooth contour the two locking segments may pass through slots in the pulley and be bent over.
