The device has an elongated guiding body designed in a form of a cylindrically shaped mantle (1). The body and a part of a component (18) of slots are connected with an air guiding element, where the slots are designed in a form of cylindrically-shaped piston. Length of a helical spring is changed corresponding to return force of a helically return spring during raise in temperature, where the spring is made of mold-memory material. The length of the spring is changed according to sinking temperature under simultaneous degradation of the return force of the return spring. The mold-memory material is selected from one of mold-memory metal or mold-memory alloy and mold-memory polymer. |
