MINIMISING CHATTER ARMATURE ELECTROMAGNETIC VALVE AT CLOSING THEREOF BY INHIBITION OF LINK IN RESIDUAL AIR GAP Russian patent published in 2016 - IPC H01F7/16 F16K31/06 F02M63/00 

Abstract RU 2592637 C2

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. Electromagnetic valve (1) with electromagnetic unit (2) has coil (5) and core consisting of inner (3) and external poles (4), with flat anchor (7), with anchor pin. Armature stroke limiter is formed in area of end side of core adjusting disc to set residual air gap between armature and electromagnetic unit. In such electromagnetic valve (1) it is possible to minimise anchor bounce when solenoid valve is closed residual air gap (18) in radial direction is closed in the section between external terminal (4) of core and external diameter of flat anchor (7).

EFFECT: technical result consists in reduction of anchor chatter when valve is closing.
