ELECTROMAGNETIC VALVE FOR SWITCHING SOURCE OF LAMINAR FLOW JET Russian patent published in 2022 - IPC F16K31/02 F16K11/72 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electromagnetic valves for switching flows of air or aerosol media; it can be used for the formation of a moving spatial image in a laminar airflow. The proposed valve is characterized by the presence of: a case with a cover, including three tubes having Y-shaped connection, two of which form input channels for two flows of an air or aerosol medium, the third forms an output channel, curtain having a part – a flap overlapping channels, an axis, and a lever part, while the flap is located in an area of connection of two input channels and is made with the possibility of movement from one position providing overlap of the first input channel to the second position providing overlap of the second input channel, at least two permanent magnets located between tubes, which correspond to input channels of the case, while the curtain is equipped with an electromagnet placed on its lever part with the possibility of movement between permanent magnets, when current pulses are supplied to the electromagnet.

EFFECT: invention provides laminar flowing of a medium in the entire time interval of operation of a device with saving high speed of switching.
