<p>The plant described resolves the problem of recovering the energy generated by heat engines under test, acceptance trials or experimental tests by the generation of alternating electrical current for which the alternator is always connected to the supply network even in the absence of mechanical energy produced by said engines under test, there being provided hydraulic pumping dynamometric units which act upon said generator through an accumulation and regulation unit which provides for smoothing out the liquid delivery rate by the action of a differential piston group adapted for exposing and closing discharge or supply apertures for the hydraulic circuit in response to the variations of power which take place during the test or acceptance cycles of said heat engines and which manifest themselves in variations in output rate of said dynamometric pumping units.</p> |
