Embodiment Construction

[0031] figure 1 The structure of the first embodiment of the piston steam engine according to the present invention is shown as an example, and the piston steam engine has a pre-combustion chamber 13, a piston 3, a cylinder 5, a connecting rod 7 and a generator (Generator) which is not shown. The coupled crankshaft 9.

[0032] Piston 3 and cylinder 5 define a working space 11 . The prechamber 13 is connected to the working space 11 . An inlet line 15 and an outlet line 17 for the working fluid communicate into the pre-chamber 13 . The output pipeline 17 of the working fluid can also be directly connected to the working space 11 (not shown).

[0033] A closable inlet valve 19 is provided in the input pipeline 15 of the liquid working medium. Liquid working fluid can be injected into prechamber 13 by means of an inlet valve, which can be configured as an injector. The injection preferably takes place when the piston 3 is in the region of the upper apex OT.

Abstract

The invention relates to a piston steam engine having flash vapourisation. Said inventive piston steam engine has a simple construction, a very good exergetic degree of efficiency and can be operated with various working mediums and at different temperatures. Also, the inventive piston steam machine can reach very high power density.

Description

Background technique [0001] Currently existing piston steam engines work with steam prepared by a steam generator. The steam is delivered through the inlet and outlet valves so that the high pressure steam reaches the cylinder space where the piston moves, during which time the steam pressure decreases and is then ejected out of the cylinder space through the piston. [0002] The steam generator required for a piston steam engine usually includes a heat exchanger in which a working medium, such as water, is vaporized at the desired operating pressure. Here, the heat required for the vaporization process is provided by a heat transfer medium, for example exhaust gas. Relatively, the heat transfer medium in the steam generator is cooled to a certain temperature within the vaporization temperature range of the working fluid. [0003] In another approach, attempts were made to realize so-called flash evaporation in rotary machines. Mention is made here of the work of Professor ...
