ABSTRACT:
A regulation device is disclosed, for regulating a physical magnitude as a function of two independent parameters: the parameters can be, for example, parameters of interest in the operation of an internal-combustion engine. Instead of the conventional space cam, a surface is provided on which the third dimension is represented by different voltage so as to define on such a planar or curved surface a family of equipotential curves. The readings taken by a conductive follower are mechanically converted so as to govern the appropriate component parts of an engine so as to have an automatical adjustment of certain parameters. The device is dependable and reliable and cannot be prone to jamming or mechanical defects. The device is of the potentiometric class.
