FIELD: mechanical engineering.
SUBSTANCE: according to invention, internal combustion engine or compressor contains housing, spatial cam coupled with pistons-pushers and end face cam providing valve timing. Grove of spatial cam has trapezium profile with angles of tilting of side walls exceeding friction angle. Two pistons - pushers are coupled with groove of spatial cam, said pistons-pushers being arranged with displacement through 180° relative to axis of rotation of spatial cam, and end face cam is provided with two projections on concentric ring surfaces. Moreover, spatial cam and pistons- pushers are arranged vertically relative to vehicle plane.
EFFECT: reduced labor input in manufacture and irregularity of motion, possibility of elimination of appearance of gyroscopic moment of forces under action of processional rotation.
