SPOOL SLEEVE DISTRIBUTION Russian patent published in 2019 - IPC F01L5/10 F01L5/06 

FIELD: machine building.

SUBSTANCE: invention relates to piston machines with sleeve distribution of working medium. Essence of invention consists in fact that spool sleeve distribution is installed in cylindrical guide and comprises driving crank shaft, wherein sleeve is connected to shaft crank by means of bushing installed on crank and hinge system with possibility of providing reciprocating and back-and-forth movement of sleeve in cylindrical guide. According to the invention, the hinge system comprises two bearing assemblies, in each of which at least one rolling bearing is installed, wherein axes of rotation of bearings of the first and second assemblies are located along the longitudinal geometrical axis of the sleeve and do not coincide with each other.

EFFECT: improving operating reliability of spool sleeve and machine drive, as well as wider range of sleeve usage, for example, in non-lubricating machines or machines with minimum lubricant consumption, in particular, in two-stroke engines with crank-chamber blowdown or compressors.
