Device for the control of the traveling speed of a motor vehicle with a vehicle-driver-actuatable gas pedal and with means for the transmission of the movement of the gas pedal to an element which element influences the fuel-air mixture particularly the throttle valve, which means contain a position encoder with a rheostat and a limit switch, the position encoder being coupled with the gas pedal. The position encoder has a housing with a hollow cylindrical interior space in which the rheostat is located, the latter being fixed to the housing prevented from twisting with one of its two relatively moveable parts. With its other part the rheostat is connected with a bell-shaped body which is rotatably mounted in the hollow cylindrical interior space and is rotatable from a rest position against the force of a return spring by means of the gas pedal as well as being provided with means via which, upon rotation of the bell-shaped body by a certain pregiven amount, an electric switch is actuatable, the electric switch being secured on the housing. |
