ELECTROMAGNETIC VALVE Russian patent published in 2018 - IPC F16K31/06 

FIELD: valves.

SUBSTANCE: group of inventions relates to the electromagnetic valve. Valve comprises: body, inlet branch pipe, outlet branch pipe, means in the form of a main valve, located between the said inlet branch pipe and the said outlet branch pipe. At that, the means in the form of a main valve comprises the main valve element. Valve comprises means in the form of a control valve, regulating the pressure difference across the said main valve element and having a control valve member, the coil, magnetically coupled to the said coil yoke assembly, and means in the form of armature for the said control valve element movement. At that, the said anchor means includes the first part, attracted by the said means in the form of a yoke to make the opening stroke, and the second part carrying the said control valve element. Wherein the said first part is configured to move relative to the said second part in the said stroke first segment for opening, and pulls the said second part in the said stroke second segment to the opening, following the said first segment. At that, the said first part is configured to move relative to the said second part at the said second part closing and pushing process initial stage after the said closing process initial stage. Between the said first part and the said second part an opening spring is arranged, the said opening spring acts on the said second part in the opening direction.

EFFECT: enabling the large opening stroke without excessive increase of the coil and the yoke assembly.
