Ilen example of levels between the upper maximum level 12 and a middle level 22, the height of which corresponds to the upper part of the float closure part 4 Corresponds if this is viewed in an open position.

The middle level is churned in such a way that below this height there is no compensation for the buoyancy is required. Below this level, the lowering of the level causes the automatic Closing the valve. to

The length of the Hebelarr.c 19 on both sides of the axis 20 can also be unequal. In this case the same buoyancy compensation effect would then be obtained by giving the counterweight | 5 a cross-section which, with respect to that of the tube 5, would be inversely proportional to the ratio of the length of the arms.
. Finally, at 23 there is shown a slide which can be adjusted by means of a lever and which is displaceable in the direction of the arrow /. If the slide is locked in position 24, the valve cannot close completely; when the slide is in the rest position 23, the valve closes completely after being triggered. If the slide is in position 24, the valve ensures that the line is filled slowly and opens automatically when it is full. The slide is then reset to the rest position 23 and the valve operates normally and triggers with full closure. The outflow of the liquid takes place according to the arrows / «, and a suitable setting of the valve is sufficient in order to achieve the triggering of this valve at a given throughput.

F i g. 2 shows an embodiment of the invention, in which the counterweight 15 <* n a cable 25 3s is suspended, which runs over a wheel 26 attached to the tube 5 at 27.

The cross-section of the counterweight 15 is equal to the annular cross-section 16 of the tube 5, and the same lift compensation effect as in the example according to FIG. 1 received.

The cross-section of the counterweight can be a lot

fold utler part of the ring-shaped cross-section of the pipe 5, and two tier prerequisites, that this difference is compensated for by the use of rope pulleys.

Claims (4)

Patent claims: J, float outlet valve for a liquid container, the bottom of which has an outlet opening designed as a valve seat, with a closure part connected to the float for the valve seat and a rod firmly connected to the closure part as a guide in the Displacements of the closure part, the closure part being removed from the valve seat by buoyancy forces is removed when the liquid level in the container is above a predetermined height and is applied against the valve seat when the liquid level uv-ar this previous height Falls marked by a facility to correct the buoyancy force acting on the guide rod from a counterweight (15), which is immersed in the liquid at a given liquid level (22) and so dimensioned and connected to the rod (16) that the weight on the counterweight (15) acting buoyancy force and by the immersion of the rod (16) at over the given Liquid level (22) increasing liquid level additionally caused buoyancy counteract and balance each other. 2. Valve according to claim 1, characterized in that the connection between the rod (16) and counterweight (15) is a horizontal bar-like, two-armed lever (10). 3. Valve according to claim 1, characterized in that the connection between the rod (16) and counterweight (15) is a rope (25) and a pulley (26). 4. Valve according to one of claims 1 to 3, characterized by a ballast flow (10) for Establishing a balance. 1 sheet of drawings
