FIELD: mechanical engineering; delivery of regulated amount of fluid medium. SUBSTANCE: electric drive has coil wound onto fixed cylindrical magnetic core hollow inside and connected coaxially with hollow valve stem in direction of medium flow. Injector has cylindrical external housing made of magnetic material whose wall is located close to above indicated coil and forms, together with core and flange, part of magnetic circuit of electromagnetic drive. Nonmagnetic partition is placed in injector between end face surface of core and ring-shaped flange on valve stem. This partition reduces to minimum strength of residual magnetic field acting onto valve member when control electric signal is switched off. EFFECT: provision of delivery of regulated amount of fluid medium. 12 cl, 6 dwg |
