SCHEME OF USING ANNULAR VALVES IN GAS DISTRIBUTION MECHANISMS IN PISTON INTERNAL COMBUSTION ENGINES

摘要

FIELD: engine building.;SUBSTANCE: invention can be used in the internal combustion engines. Internal combustion engine includes in each cylinder at least one annular valve (8, 9) of gas distribution. Annular valve (8) is located directly above cylinder (4) bushing, contains working surface interacting with working surface on cylinder bushing. Cylinder sleeve comprises working surface interacting with working surface of annular valve located directly above cylinder bushing. Annular valves (8, 9) are located directly above each other, contain working surfaces interacting with each other.;EFFECT: technical result consists in improvement of efficiency and power of engine by increasing flow sections of inlet and outlet channels.;1 cl, 4 dwg
