HEAT ENGINE, METHOD OF CONTROL OF THE ROTATIONAL SPEED IN A HEAT ENGINE, AND METHOD OF DESIGN OF A CAM PROFILE FOR A HEAT ENGINE

摘要

Heat engine comprising a body (2) provided with an annular cavity (3) therein, two coaxial discoidal sectors (7, 7′) that comprises two diametrically opposite tangential pistons (7a and 7c or 7′b and 7′d) that project, both radially and axially, from their corresponding discoidal sector and can slide through the annular cavity, each pair of consecutive pistons defining a chamber (Cab, Cbc, Ccd, Cda), a means of control of the rotational speed of the two discoidal sectors that makes their respective rotational speeds to vary cyclically and in antiphase between a maximum speed and a minimum speed, so that the speed of each sector is kept at a substantial maximum for most of the duration of a half-cycle, and is kept at a substantial minimum for most of the duration of the other half-cycle, and a means (8) of integration of the speeds of the sectors into a mean speed for the power transmission shaft (9).
