FIELD: mechanical engineering; designing and developing of internal combustion engines for use as power units in small-size devices. SUBSTANCE: engine has cylinder head 1 with space 2 formed by upper plate 3 of cylinder head 1 and side walls 4 and 5. Space accommodates support 6 with axle 7 carrying valve rockers 8. Support 6 is made in form of U-shaped clamp with projections 10 and 11 on sides for fastening on side walls 4 and 5 cylinder head and is installed with clearance δ between lower plane of support 6 and upper plate 3 of cylinder head 1. Valve rockers 8 are arranged in row between side parts of support. EFFECT: increased service life of engine by stabilizing clearances between valves and rockers under various operating conditions. 3 dwg
