Abstract

A tank filling device for a liquid container has a base body with mounting end to secure the base body on a liquid container. An actuating section is disposed in the base body interior and slidable lengthwise relative to the base body. A liquid valve is connected to an outlet opening for liquid and controls the outlet opening by being coupled to the actuating section such that the liquid valve is manually opened or closed by moving the actuating section. An air channel with air inlet and air outlet supplies air into the liquid container for pressure compensation. The air channel extends from the liquid valve toward the mounting end and has an air valve at the air outlet. The air outlet is provided between the actuating section and the base body and is a slot control valve formed by actuating section and base body.

First claim

What is claimed is:

1. A tank filling device for a liquid container, the tank filling device comprising:
a base body comprising a mounting end configured to secure the base body on a liquid container;
an actuating section disposed in an interior of the base body so as to be slidable lengthwise relative to the base body, wherein the actuating section comprises a first end and a second end opposite the first end in a length direction of the actuating section, wherein the first end is facing the base body and the second end is facing away from the base body;
an outlet opening for outflowing liquid;
a liquid valve operatively connected to the outlet opening for controlling the outlet opening, wherein the liquid valve is arranged at the second end of the actuating section and coupled to the actuating section such that the liquid valve is manually opened or closed when the actuating section is moved relative to the base body;
an air channel comprising an air inlet and an air outlet and further comprising an air valve disposed at the air outlet, the air channel configured to supply air into the liquid container for pressure compensation in the liquid container, wherein the air channel extends from a region where the liquid valve is arranged in a direction toward the mounting end, wherein the air valve is arranged at the first end of the actuating section and is spaced apart from the liquid valve in the length direction;
wherein the air outlet of the air channel is provided between the actuating section and the base body;
wherein the air valve is embodied as a slot control valve and is formed by the actuating section and the base body;
wherein the air valve and the liquid valve are mechanically coupled with each other such that sliding the actuating section relative to the base body displaces the air outlet, and the air outlet is positioned such that the air valve opens with delay relative to the liquid valve.

2. The tank filling device according to claim 1 , wherein the air outlet of the air channel is provided in the actuating section and is facing an inner wall surface of the base body.

3. The tank filling device according to claim 1 , wherein the air valve comprises a compensation cross section that is open in a closed position of the air valve.

4. The tank filling device according to claim 3 , wherein the air valve has an opening cross section in an open position of the air valve and wherein the compensation cross section amounts to 1% to 5% of the opening cross section of the air valve.

5. The tank filling device according to claim 1 , wherein the air inlet of the air channel is positioned in a plane of the outlet opening.

6. The tank filling device according to claim 1 , wherein the liquid valve comprises a valve seat and a valve member, wherein the valve member is configured to close both the liquid valve and the air inlet.

7. The tank filling device according to claim 6 , wherein the valve member is a valve plate.

8. The tank filling device according to claim 6 , wherein the liquid valve comprises a valve stem centrally penetrating the actuating section and wherein the valve member is secured on the valve stem.

9. The tank filling device according to claim 1 , wherein the air inlet comprises a compensation opening and the compensation opening remains open relative to the interior of the base body when the liquid valve is in a closed position.

10. The tank filling device according to claim 1 , wherein the actuating section comprises a divided interior, wherein the air channel is provided in the divided interior, wherein the divided interior further comprises a liquid channel, wherein the liquid channel and the air channel extend straight in the divided interior along a longitudinal axis of the actuating section.

11. The tank filling device according to claim 1 , wherein the air outlet opens at a circumferential region of the actuating section.

12. A tank filling device for a liquid container, the tank filling device comprising:
a base body comprising a mounting end configured to secure the base body on a liquid container;
an actuating section disposed in an interior of the base body so as to be slidable lengthwise relative to the base body, wherein the actuating section comprises a first end and a second end opposite the first end in a length direction of the actuating section, wherein the first end is facing the base body and the second end is facing away from the base body;
an outlet opening for outflowing liquid;
a liquid valve operatively connected to the outlet opening for controlling the outlet opening, wherein the liquid valve is arranged at the second end of the actuating section and coupled to the actuating section such that the liquid valve is manually opened or closed when the actuating section is moved relative to the base body;
an air channel comprising an air inlet and an air outlet and further comprising an air valve disposed at the air outlet, the air channel configured to supply air into the liquid container for pressure compensation in the liquid container, wherein the air channel extends from a region where the liquid valve is arranged in a direction toward the mounting end, wherein the air valve is arranged at the first end of the actuating section and is spaced apart from the liquid valve in the length direction;
wherein the air outlet of the air channel is provided between the actuating section and the base body;
wherein the air valve is formed by the actuating section and the base body and is embodied as a slot control valve such that the air outlet opens in a circumferential region at the outer circumference of the actuating section and such that the air outlet has associated therewith a control slot disposed in an inner wall surface of the base body, wherein the control slot is a cutout extending axially across a height of the base body;
wherein the air valve and the liquid valve are mechanically coupled with each other such that sliding the actuating section relative to the base body displaces the air outlet, and the air outlet is positioned such that the air valve opens with delay relative to the liquid valve.
