发明名称 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 A heat engine comprises two coaxial discoidal sectors and a mechanism of control of the rotational speed of the sectors that makes their respective rotational speeds to vary cyclically between a maximum and a minimum speed. The mechanism includes a linked structure provided with four links arranged in a deformable parallelogram and connected to each other by corresponding rotary joints located at their ends, each link including a roller located adjacent one end of the link. The mechanism further includes at least one cam profile for the rollers to follow, the cam profile being the locus of the path followed by the rollers when the sectors follow a motion such that the speed of each sector is kept at a maximum for at least 90% of the duration of a half-cycle, and is kept at a minimum for at least 90% of the duration of the other half-cycle.

主权项 1. A heat engine comprising: a body provided with an annular cavity therein; two coaxial discoidal sectors that jointly define at least four chambers in the annular cavity; a mechanism of control of a 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 volume of the chambers varies too; said speed control mechanism comprising a linked structure provided with four links arranged in a deformable parallelogram that is parallel to the discoidal sectors, said links being connected to each other by corresponding rotary joints located at their ends, and each link comprising a roller located adjacent one end of the link; the speed control mechanism further comprising at least one cam profile for the rollers to follow, the cam profile extending in parallel to the discoidal sectors;wherein: a shape of the cam profile is the locus of the path followed by the rollers when the discoidal sectors follow a determined motion, said determined motion being such that the speed of each discoidal sector is kept at a maximum for at least 90% of the duration of a half-cycle, and is kept at a minimum for at least 90% of the duration of the other half-cycle.
