FIELD: engines and pumps.
SUBSTANCE: actuator comprises multipole rotary electromagnet with axis directed perpendicular to the plane extending along camshaft and high-pressure fuel pump pressure section axes. Besides, it comprises fuel pump control rack drive link articulated with adjustable-length con-rod of high-pressure fuel pump. Rotary electromagnet armature is composed by permanent magnets. Tips are fitted at electromagnet plunger and shaped to circular variable-thickness sectors, said thickness decreasing in direction of armature rotation towards fuel feed decrease.
EFFECT: higher reliability of actuator, ruled out application of spring for emergent outage of diesel.
