<p>The present invention provides a process for converting the internal energy of a fluid into mechanical energy capable of producing work, said fluid having liquid and gaseous states, at temperatures respectively below and above, its critical temperature, which process comprises the interconnection of four operative steps, in the first step of which the fluid is liquefied at a temperature and a pressure below the critical temperature and pressure thereof, and introduced into a chamber provided with means for transmitting movement and means for transmitting heat; in the second step of which said liquefied fluid is subjected to a rapid heating, to exceed the critical temperature, the pressure is considerably increased, and the fluid is converted to the gaseous state; in the third step of which the fluid is expanded in the chamber against the resistance offered by the means for transmitting movement; and in the fourth step of which means are provided, whereby the fluid recovers and returns to the initial conditions of the first step. The present invention also provides a machine for use in the process.</p> |
