In a control device for remote actuation of a member 15 in opposition to a spring 7 by means of a cable 4 the control device is also provided with a spring 23 which acts in opposition to the spring 7 and with an equal force to spring 7 irrespective of the position of the control device. A pair of devices may be used to control flaps 15, 16 in a vehicle ventilation system, operated by a cam plate 10. The opposing forces to springs 7 are provided through levers 24, 25 acting on the cam plate. In an alternative embodiment a spring-biassed semi-circular wheel operates a flap through the cable 14. The arrangement reduces the force required to adjust a ventilation flap and permits it to stay in intermediate adjusted positions without a constant force being applied. <IMAGE> |
