  • a hot water engine comprises two groups of pressure vessels with associated liquid piston pumps, which act on a working cycle of a water turbine. During a first cycle, a warm, expanding gas or gas mixture is present in the first pressure container and the second pressure container contains a cold, contracting gas or gas mixture.
  • the gas or gas mixture of the first pressure vessel is cooled by injecting cold water and the gas or gas mixture of the second pressure vessel is heated by injecting hot water, so that the gas volumes change accordingly.

  • the valve is opened by appropriate expansion or contracting and the associated driving of a displaceable piston of the hot water engine, the piston being able to be designed as a liquid piston pump. Since the gas mixture heated in a first cycle is cooled in a subsequent second cycle, it is necessary (to lower the temperature of the gas mixture of this container below the equilibrium temperature, the remaining heat of the gas mixture being used to heat the cooled and now to heating gas mixture is used. The residual heat is therefore not lost unused, which is why a relatively large output is achieved with a relatively low technical outlay. The residual heat also does not get into the working circuit of the hot water motor, from which it had to be extracted.
  • the short-circuit pipeline is arranged in the upper region of the pressure vessel.
  • this area of the pressure vessel in which there is a flange or a cover, there is neither hot nor cold water, which is why the gas mixture can get into the short-circuit pipeline undisturbed through the open valve.
