ABSTRACT:
A motion transmitting remote control assembly of the type for transmitting motion in a curved path to open from a remote location at least one vent door which is held in a closed position by latches which engage the door, the assembly including core elements for transmitting linear motion along a curved path and an actuator for actuating the linear motion of the core elements. Conduits guide the path of the core elements. The core elements include a portion extending from the conduits and adapted to be operatively connected to the latches of the vent door whereby operation of the actuator actuates linear motion of the core elements to disengage the latches from the vent door.
