Thermal machine, process control rotation speed in a thermal machine, and process design a cam profile for a heat engine.

摘要

thermal machine comprising a body (2) provided inside an annular cavity (3), two coaxial discoidal sectors (7, 7 ') comprise respective diametrically opposed tangential pistons (7a, 7c, 7'b, 7'd ) projecting radially and axially of its corresponding sector and can slide inside the annular cavity, in which each pair of consecutive pistons defining a chamber (C {sub, ab}, C {sub, bc} C {sub, cd}, C {sub, da}), means for controlling the speed of rotation of the two sectors that make their rotational speeds vary cyclically in antiphase between a maximum speed and a minimum speed, so that the speed each sector remains high substantially throughout most of the time of a half cycle, and remains high substantially throughout most of the time the other half cycle, and means (8) integration speeds sectors at an average speed to the axis (9) of transmi sion power.
