Title: Steam engine
Inventor: YATSUKA SHINICHI
IPC: F01B31/26
Filed: 2002-08-26
Abstract: <P>PROBLEM TO BE SOLVED: To improve efficiency of a steam engine while solving problems such as corrosion and abrasion at a portion for receiving steam pressure.  <P>SOLUTION: A heater 12 and a cooler 13 are installed on one side of a U-shaped fluid container 11, and an outputting piston 14 is installed on the other side. Because steam of working fluid heated and evaporated by the heater 12 presses down a liquid surface on a first perpendicular part 11b side with expansion pressure, a liquid portion of the working fluid is fluidized and displaced from the first perpendicular part 11b towards a second perpendicular part 11c, so that pressure in a direction for pushing up the piston 14 acts on the piston 14. At that time, because the liquid portion of the working fluid functions as a liquid piston for directly receiving expansion pressure of the steam, such problems are not caused in principle as corrosion and abrasion of the portion for receiving the steam pressure. Because there is no need for taking a measure for heightening superheat of steam in advance, energy conversion efficiency can be heightened to a level equivalent to Carnot cycle.  <P>COPYRIGHT: (C)2004,JPO
