MULTI-PORT VALVE FOR SWITCHING, DOSING AND MOVING SMALL FLOWS AND QUANTITIES OF LIQUID Russian patent published in 2022 - IPC G01F11/02 

FIELD: multiport valves.

SUBSTANCE: multiport valve is designed for switching, dosing and moving small flows and quantities of liquid. The valve consists of a body, branch pipes, fitting, combined with a stepper motor shaft; an elastically deformable part, which, when switching channels, locks and unlocks the latter by interacting with structural details. The elastically deformable part is made in the form of an elastic sleeve by curing the material directly in the valve; switching the latter; moreover, at the end of the fitting there is a branch pipe connected by a channel with an opening on the cylindrical part.

EFFECT: increasing the reliability of the device, ensuring the most accurate and tight fit of the mating surfaces; device has a small internal volume of the hydraulic lines, and therefore the fluid flow is used as rationally as possible.
