ELECTROMAGNETIC DRIVE FOR VALVE Russian patent published in 2005 - IPC

FIELD: valving.

SUBSTANCE: electromagnetic drive comprises armature provided with rod rigidly connected with the armature and spring-loaded in the direction to the stop and armature. When the drive is switched in, the faces of the armature and the stop are in a contact and are made of trancated cones with generatrices. The generatrices are inclined at an angle of 40° - 50° to the axis of the drive and arranged at the bases of the cones. The ring surfaces of the cones are perpendicular to the axis of the drive. The top of the trancated cone is provided with the ring shoulder whose diameter relates to the outer diameter of the armature as 0.5 - 0.6. The outer sealing flange is provided with radial throttle orifice. The leads of the winding of the drive are connected in parallel to the power source and the source of lowered voltage.

EFFECT: enhanced reliability.
