METERING DEVICE FOR FLUID Russian patent published in 2011 - IPC G01F11/02 

FIELD: machine building.

SUBSTANCE: metering device consists of delivery reservoir, of pipe with slit vertically installed into reservoir, and of hollow cylinder with slit in form of vertical set isosceles triangle and tap. The cylinder installed inside the pipe travels relative to it. According to the invention the slit of the pipe is made in form of trapezium bases of which are parallel to each other and to a bottom of the reservoir. Sides of trapezium are inclined to a lower base at angle equal to angle at base of a vertical triangle slit, while vertical symmetry axis of trapezium coincides to bisector of the said triangle slit of the hollow cylinder. With its lower end the pipe with the slit is connected to a bottom of the reservoir by means of a circular elastic hose, while in a part of the reservoir projecting under the bottom the hollow cylinder is equipped with a two-way cock for delivery and discharge of fluid. A float valve for outlet and inlet of air is set on a cover of the metering device.

EFFECT: automatic process of fluid dispensing, upgraded accuracy of metering and reduced time for dose measurement.
