<p>This document is only an illustration and not an explicit account of the invention presented. This device is basically an annular link built and used as presented in the explanation. It allows and determines the relative movements of mechanical elements (with circular, or rather circular portion, plan view) inside a spherical surface (or portion of a spherical surface) in which they are enclosed. The elements' movements or the combination of their movements is such as to determine the cyclic variation of volume of chambers delimited by the elements (of which the system is composed).</p> |
