FIELD: mechanical engineering; engines, pumps and compressors.
SUBSTANCE: proposed blade-crankless machine has internal combustion blade engine and piston compressor mounted on one power shaft. According to first design version, compressor is provided with cylinder of inner surface of which at least two non-closed screw grooves are made, and piston with two running balls installed in cavities on outer surface of piston for rolling in cylinder grooves. According to second design version, compressor is provided with piston on outer surface of which at least two non-closed screw grooves are made, and cylinder with at least two running balls installed in cavities on inner surface of cylinder for rolling in piston grooves. Piston in both design versions is movably connected with power shaft by means of blocks installed on shaft and running balls installed in pairs in space between blocks and races made on inner surface of piston.
EFFECT: improved technical, economical, mass and dimensional parameters and characteristics of machine.
