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 the fact that spool sleeve distribution is installed in cylindrical guide and comprises drive crankshaft, to which it is connected using crank installed on crank, as well as a connecting rod and a hinge system allowing the sleeve to perform alternating and reciprocating rotary movement in the cylindrical guide. According to the invention, the hinge system comprises two bearing assemblies, in each of which there is at least one rolling bearing with possibility of receiving both radial and axial load, wherein the plane of rotation of the bearing of the first assembly of the hinge system crosses the plane of rotation of the bearing of its second assembly.

EFFECT: technical result of claimed invention is higher reliability of drive of spool sleeve and machine, as well as wider range of use of sleeve, for example, as gas distribution mechanism in two-stroke engines with crank-chamber blowdown.
