ELEMENT FOR IC ENGINE WITH MOBILE COMBUSTION CHAMBER

摘要

The engine according to the invention comprises: a) a casing (12) inside which an annular cavity is formed; b) an annular rotor (14), housed within the annular cavity; c) multiple mobile chamber elements (10), secured to the rotor (14). The annular cavity has, in some regions, cross-sectional sizes substantially greater than the cross-sectional sizes of the rotor (14) so as to define multiple hollow chambers (16, 18). The mobile chamber elements (10) can be displaced, within at least part of the hollow chambers, transversally relative to the annular body of the rotor (14) while contacting the walls of the same annular cavity and separating in fluid-tight manner the hollow chamber portion in front of the mobile chamber element (10) from the hollow chamber portion behind the mobile chamber element (10). The engine has combined functions of compression chamber, combustion chamber, valve, member defining the portions with cyclically variable volume, device for compressed gas translation.
