The conversion of heat into mechanical energy is in most instances performed by way of reciprocating pistons, the reciprocating movement of which must be converted into a rotational movement. Innovations which convert heat energy directly into a rotary movement, whether by way of turbines or rotary engines, have been used only for special applications. The present invention is intended to overcome the disadvantages of both the reciprocating piston engines and of the known heat engines (turbines, rotary engines), the aim being to convert heat directly into rotational energy, in that there are only concentrically rotating parts, which during a full revolution are not subjected to any acceleration or deceleration due to the type of mechanical construction. The heat engine described in the present specification has pistons rotating in an annular cylinder, which is separated by one or more rotating valve circular discs so that the processes known from the principle of heat engines, such as induction, compression, expansion and exhaust can be achieved and that the piston(s) rotating in the annular cylinder can pass through the said valve disc(s). As a piston approaches a valve disc the passage is freed by a recess in the disc corresponding to the piston.
