EXPEDITION GENERATOR Russian patent published in 2017 - IPC H02K7/18 F02G1/53 

FIELD: electricity.

SUBSTANCE: expedition generator comprises a heat exchange housing. The heat exchange housing is made in the form of a hollow airtight cylinder. Along the longitudinal axis of the airtight cylinder, on the inside, there are an alternator, a working cylinder with a piston, and a displacer. The displacer is made in the form of a hollow cylinder. One end wall of the displacer has a cylindrical recess repeating the working cylinder in shape. In the deepest part of the recess, the displacer wall has openings for the working fluid exchange between the working cylinder and the buffer capacity. The buffer capacity is located inside the displacer. The winding of the alternator stator can be located inside the walls of the working cylinder or the heat exchange cylinder. The moving magnetic poles of the alternator are located on the working piston. The displacer may comprise a regenerator. The heat exchange housing may comprise a regenerator.

EFFECT: reducing the overall dimensions and mass of the generator while maintaining the working volume and pressure of the working fluid.
