Abstract
In an installation for harnessing thermal energy, in which in a first part of an operating cycle the working fluid is positively displaced out of a first chamber into a second chamber, in which a higher temperature prevails than in the first, and in a second part of the operating cycle working fluid is positively displaced from the second chamber back into the first chamber, wherein thermal energy is supplied to the working fluid on its passage from the first to the second chamber and removed from the working fluid on its passage from the second to the first chamber, the chambers are formed by variable-volume working chambers of piston machine units (10, 12, 14, 16) coupled with one another and operating out of phase with one another, which communicate with one another by fluid ducts (18, 20, 22, 24) in such a way that the working fluid is positively displaced out of a shrinking work chamber having a relatively high temperature through a first duct, into an expanding work chamber having a lower temperature, and at the same time, working fluid from a shrinking work chamber having a lower temperature is positively displaced through a second duct into an expanding work chamber having …
