TWO-STROKE AXIAL PISTON THERMAL MACHINE-ENGINE Russian patent published in 2015 - IPC F02B75/00 

FIELD: machine building.

SUBSTANCE: two-stroke axial piston thermal machine-engine contains piston 2 installed in the cylinder 1 secured on the crankcase 6, movement transformation gear, double fork output shaft 8 connected by the fork arm with carriage 14 of the movement transformation gear. The carriage 12 axle has trunnions with the installed on them bushings resting against the race. The carriage is connected with the piston by means the stock 9, its bottom head is rigidly connected with the internal bearing race located in the carriage socket, and the top head is rigidly connected with the piston. The under-piston cavity is separated from the crankcase by the inserts 3 with gland installed in it and having hole for the stock 9. The crankcase space and insert separating it from the under-piston cavity create the oil cavity in which the most loaded elements of the movement transmission and transformation gear are installed.

EFFECT: increased operation reliability due to improved lubrication quality and improved thermal operation conditions of the most loaded friction elements of the movement transmission and transformation gear, and assurance of most favourable conditions for the two-stroke cycle implementation.
