Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; valves working at high temperatures up to 2300 K and pressures up to 10 MPa for control of flying vehicle thrust vector. SUBSTANCE: valve has body with inlet and outlet branch pipes and seat with bearing unit whose cylindrical hole is used for slide fit of cylindrical control member which is kinematically linked with shaft; during rotation, it overlaps flow opening of seat. Outer cylindrical surface of control member is provided with circular bore over entire width of flow port of control member. Outer cylindrical surface of circular bore is concentric relative to outer cylindrical surface of control member. EFFECT: enhanced operational reliability. 4 dwg
