FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to fuel injection devices. Proposed electromagnetic metering valve with ball stopper for nozzle contains ball acting onto conical seat to close discharge pipeline of nozzle control chamber, and electromagnet to energize armature which controls operation of cylindrical rod coaxial with conical seat and usually flexibly pushed to hold in closed position relative to conical seat. Rod is directed by guide bushing, also coaxial with conical seat. Disengageable joint is found between rod and ball to transmit action of rod onto ball coaxially with conical seat and reduce possibility of armature caused by wear under action of ball. EFFECT: simplified design, improved reliability and response. 6 cl, 43 dwg
