FUNNEL Russian patent published in 2020 - IPC B67C11/00 

FIELD: technological processes.

SUBSTANCE: invention relates to design of devices for distribution of liquid substances or for their movement from one container to another container with narrow neck. Design can be used for domestic and industrial needs, for maintenance of vehicles and in technical power-driven power facilities operated in field conditions. Set objective is structurally achieved by the fact that in the funnel containing the extension, a cone, a neck, a spiral conical element located in the cone, in accordance with the present invention, an extension in the cross-section, flow part of the cone and neck are made in the form of a helicoidal surface, wherein the helicoidal surface in the cone and in the neck is made tapering and spirally twisted with increase in the spin length from the inlet of the cone to the outlet of the neck, helicoidal surface has main and additional spiral helicoidal projections, swirled opposite to twist of helicoidal surface with spiral pitch increased with respect to pitch of twist of helicoidal surface, which increases from inlet of cone to outlet of neck, and the spiraling rotational movement of the liquid inside the funnel is provided by the shape and twisting of the helicoidal surface, by twisting the main and additional projections, as well as creation of "liquid bearing" by additional helical helicoidal projections, through which the main spirally swirled accelerating liquid flow slides with minimum friction at its flow from funnel.

EFFECT: increased rate of liquid flow through the funnel.
