Motive device for converting a variation in temperature into mechanical energy
The invention relates to a motive device adapted to convert a variation in temperature to which it is subjected into mechanical energy, constituted by a piston mounted to slide by one of its ends in a first chamber and by the other of its ends in a second chamber, said chambers being connected with each other so as to define in the first chamber a first closed volume and in the second chamber a second closed volume, particularly larger than the first, each of said volumes being filled with elastomer under pressure so that each chamber and each corresponding end of the piston constitute a spring involving the hydrostatic compression of the elastomer. The invention is applied to the construction of devices for thermally regulating the functioning of a mechanism.
