DE19507019A1 - Funnel with non return valve - Google Patents

Abstract

The non-return valve (12) which is in the form of a hollow ball is mounted on the end of a stem (7) which runs in the centre of the funnel. The valve is located in the cylindrical spout of the funnel. The valve stem (7) is guided in a sleeve (6) which is attached to a cross strip (8). When pressure is building up in the container (14), into which liquid is being poured, the valve is pushed up against a valve seat. The valve stem incorporates a hinge (4) so that the top half of the stem can be hinged down and secured under one of he hooks (3) on the funnel edge. This keeps the valve permanently closed.

Description

State of the art

Conventional design hopper for filling containers (Tanks, barrels, bottles, etc.) must be with extreme caution should be used, otherwise the too filling container overflows when in the funnel is filled too much.

problem

The invention specified in the claim is Underlying problem of creating a hopper that when filling containers of any kind with unvers visible filler neck, or not transparent Material (glass, plastic, etc.) overflow the liquid to be filled prevented.

solution

This problem is solved with the in claim 1 Features listed solved.

Achieved advantages

With the invention of this device it is achieved that overflow of the container to be filled is prevented becomes. The otherwise overflowing liquid remains in the Funnel, as it seals automatically from below before the overflow point is reached. The residual liquid remaining in the funnel can be filled back into the filling container. No pollution or contamination from over running oily or chemical liquids. When filling the tanks of work machines (none Seepage into the ground).

When filling ship tanks (no water contamination).  

Way of working

The mechanism specified in claim 1 works as follows:
To simplify: vessel to be filled, here z. B. called tank. Filling vessel, here z. B. called canister.
As usual, the funnel is inserted with its outlet nozzle into the tank nozzle.

The tank is now filled with the canister.

If the tank is almost full, the pressure will cause the The float in the funnel neck is filled with fuel pushed up.

The float presses against a seal and leaves no more liquid in the tank. Because the swimmer himself partially located inside the tank is an over running of the tank is no longer possible.

The swimmer simultaneously presses the one connected to it Push rod through a guide upwards. The one with the The push rod connected to the float consists of two parts pieces that are connected to each other by means of a joint are. Now the swimmer has to fill the tank reached its height and against the above Seal presses the push rod has reached its highest level at the same time and the upper push rod part kinks over the end of the Push rod guide horizontally and falls on the Funnel edge. Now the canister can be put down although the funnel may still be half full, but is sealed by the float.

Now push the upper push rod into one of the am upper funnel edge all around clamps snapped into place. The funnel can now be removed from the tank be taken out without the in it remaining liquid runs out. The funnel neck is inserted into the canister and by disengaging the the upper push rod from the clamping device is released Float from the seal and the liquid gets into the Canister filled back.

However, the float can be spherical (as shown in the sketch) also have a conical shape, a cylindrical shape or other shapes. Push rod and push rod guide can also be used by others Cross sections have as indicated in sketch.

Claims (1)

Entire on and in a conventional funnel brought construction that the funnel through from below coming pressure (which arises in the container to be filled) by floating swimmers automatically below closes and by the mechanism at the top Funnel edge can be firmly jammed.
