    摘要: A throttle-valve housing of plastic has a metal insert which achieves dimensional stability in the region of the throttle valve. The throttle-valve housing is formed of plastic with a cavity bounded by an inner wall surface. In the wall there is arranged a metal insert which is covered on all sides by the plastic material and effects a stabilization of the plastic material, so that distorting, shrinking or the like is prevented and dimensional accuracy of the inner wall surface is ensured. The novel throttle-valve housing is simple to produce and has a high dimensional stability in spite of being formed from plastic material. The throttle-valve housing is suitable for internal-combustion engines of motor vehicles.

    摘要: A throttle device having a throttle-flap connection piece which is produced from plastic. For an efficient production of the throttle-flap connection piece form plastic in the plastic injection-molding technique, it is necessary to avoid undesirable shrinkage in the pivoting region of the throttle flap and to seal off the bearing arrangements against penetrating plastic during the injection operation. The throttle device includes an annular insertion part which is arranged in the pivoting region of the throttle flap and which, connected to the bearing arrangements is embedded into the throttle-flap connection piece made form plastic, in order to protect the bearing arrangement against penetrating plastic. The injected-round insertion part is suitable for throttle devices which are made from plastic and which are provided for mixture-compressing spark-ignition or air-compressing auto-ignition internal-combustion engines.

    摘要: 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.

    摘要: A control for a throttling member, for example a throttle butterfly of an internal combustion engine. The actuating device has an actuating member which is designed as a plastic part and is molded onto one end of an adjusting shaft by means of an inner fixing sleeve and a recess made in the adjusting shaft in the form of a slot which is filled with plastic, thus allowing reliable torque transmission. The actuating device is suitable for throttling devices of mixture-compressing, spark-ignition or air-compressing, self-ignition internal combustion engines.

    摘要: A device is disclosed for regulating the intake air temperature in an internal combustion engine. It comprises a cold air duct, a warm air duct and a mixed air duct, the mixed air duct, also called primary air duct, is provided with a control flap, which in one final position closes off the cold air duct and in the other final position closes off the warm air duct and can pivot under the action of a wax-type thermostat around which the cold intake air flows. The wax-type thermostat is provided with a tie rod connecting it to the control flap. A restoring spring is located on the tie rod. In addition, an excess travel spring is provided to compensate for the excess travel of the wax-type thermostat. The control flap has longitudinal guiding means designed to take up the excess travel, the excess travel spring being mounted on longitudinal guiding means.
