SU25745A1 - Meter for liquid fuel - Google Patents

Description

The invention relates to a liquid fuel measuring device consisting of two vessels located one under the other, of which the upper one serves to measure the liquid, which then overflows into the lower flow vessel, and is provided with a float acting on the stop valves, and in order to prevent the liquid from the measuring vessel prior to the release of the supply vessel, the latter is also provided with a float acting on the inlet valve of the measuring vessel.

In the proposed measuring device, to control the supplying and discharging Valves, an eccentric is attached to the levers associated with the float of the upper vessel and equipped with a spring to hold it in the extreme positions; To close the feed valve directly, in case the filling chamber is filled with liquid, the float of the latter is provided with a cylindrical part acting on the valve.

In FIG. 1 is a vertical sectional view of a meter for liquid fuel; FIG. 2 extreme positions of the eccentric.

In the presence of liquid fuel in the supply bottom vessel 1 at level k,

those. below the hole d, the float 5 vd1este

with feed valve 8 drops to

its lower position and valve 8

will open the hole / through which the liquid fuel through the tube and from the supply tank enters through the channel c - into the upper measuring vessel 2.

The float 4 begins to rise along with the arms 7 which are movably connected to it and rigidly connected with the eccentric 14. The latter is equipped with a spring 6 which holds it in the positions (Fig. 2). When the levers 7 are raised, the eccentric 14 rotates together with the spring 6. When the spring b moves into its middle position, it flips to position II (Fig. 2), together with the eccentric 14 and the lever 7, turning the eccentric 90 °. Spring 10 all the time through the outlet valve 9 keeps the hole t closed. At the indicated rotation of the eccentric 14, the latter presses the ends of the levers 15 and 11 acting on the valves 9 and 8. The valve 9 opens the hole m and the fuel flows from the measuring vessel 2 to the expendable 1 and at the same time, the valve 8 closes the opening I and stops the access of the new portion of fuel to the vessel 1. As the fuel is released from under the float 4, the latter lowers and, by means of the hooks, pulls the levers 7 behind him, turning the eccentric 14 with the spring 6. P It moves to the extreme position 1 (Fig. 2) and the whole system is brought to its original position when the opening t is closed and the opening / opening is open. In the case when there is no fuel consumption in the carburetor, the fuel filling the lower vessel 1, through the hole d enters the float 5, provided with the upper cylindrical part 5, which, when the float rises with increasing level in the vessel 1, directly closes the valve 8 and When stopping the access of fuel to the upper vessel 1. To protect the float 5 from rotation, the last one is equipped with a guide rod 13. For counting the amount of fuel, the eccentric 14 is connected with a counting mechanism.

The subject matter of the invention.

Liquid fuel meter with two located one under

to other vessels, of which the upper serves to measure the liquid, then overflow into the lower, supply vessel, and is provided with a float acting on the shut-off valve, and the lower supply vessel is also provided with a float to prevent liquid from the measuring vessel prior to the release of the consumable vessel, characterized by the use of for controlling the supply valve 8 and the outlet valve 9 in the form of an eccentric 14 connected to the levers 7 and fitted with a spring 6 for holding it in one of the extreme positions corresponding to the closing whether the opening of the valves 8 and 9 than when the float 5 is provided with an upper cylindrical part 5 for immediate closing of the valve 8 in the case of filling a liquid flow chamber 1.
