FIELD: engines and pumps.
SUBSTANCE: endothermic engine comprises multiple combustion chambers, each being provided with, at least, one valve and valve opening lever 11. Camshaft 1 has multiple cams to control aforesaid lever. Cylinder head has support axle 2 supporting offset sleeves 16 fitted to turn thereon and to support one of levers turning there about. Actuator 8 allows sleeves to turn through preset angle. Sleeves 16 are made integral to turn about support axle by means of plate 12 rigidly coupled, at least, in direction of turn. Plate 12 features the shape of cylindrical surface sector with axis of symmetry coaxial with support axle.
EFFECT: ruling out mechanical strains causing friction between sleeves and axle.
