Engine utilizing expansion and contraction of mercury - in closed circuit with heater and cooler to produce mechanical energy

摘要

The engine may be of the rotary piston type and may be so constructed that it can also be used as a combustion engine or pump. In a closed chamber the mercury is electrically heated. The expanded mercury forces itself through inlet pipes into a cylinder space. After the power stroke, the mercury is discharged to a cooling vessel in which under atmospheric pressure is cooled to approx. 0 deg.Cafter which a piston arrangement first draws, and afterwards pumps it into a heating vessel.
