ABSTRACT:
An external combustion engine comprises an actuating cylinder in which a piston with rod is mounted for reciprocation, said piston serving as the actuating member, a valve distributor serving as the switching member, as well as a crank gear serving as the converter of the piston reciprocation to the drive shaft revolution. The piston divides the cylinder cavity into two, namely, a rod cavity and a rodless cavity. Each one of the cavities communicates with a source of working fluid via valve distributor. The piston rod is operatively connected with the drive shaft via crank gear. The engine further comprises an electric oscillator whose frequency is variable in accordance with the preset r.p.m. of the drive shaft, connected electrically with the converter in the form of a linear dynamic link, and a transducer indicating the current value of the piston position relative to its neutral position. The linear dynamic link is coupled mechanically with the distributor slide valve. The transducer of the current value of the piston position is coupled by means of negative electric feedback to the converter, and mechanically--to the piston rod.
