Filling device
First Claim
1. Filling device, comprising a filling pipe (4) for the manual guidance and for cooperation with a pipe connector (2) located over a filling opening (34) in a tank container (34) for suitable receptacle;
- a vale (24) arranged in said filling pipe (4);
a vent valve (2) and at least one connection for a flexible infeed conduit communicating with said filling pipe; and
means for actuating said valve (24) and vent valve (20), said valve (24) being arranged at an outer end of the filling pipe (4) which is extendable through said pipe connector (2), said means causing said valve (24) and said vent valve (2) both to be automatically actuated in dependence upon a proper connection being formed between the filling pipe (4) and said pipe connector (2), said actuating means comprising;
(a) a first sleeve component (6) encompassing the filing pipe (4) and being open at the end thereof towards the pipe connector (2) and forming an attachment for the filling tube (4) on the pipe connector (2),(b) a second sleeve component (9) coaxially encompassing said first sleeve component (6) and sealingly encompassing said filling pipe (4),(c) said sleeve components (6,
9) being axially guided sealingly slidable within each other, said second sleeve component (9) cooperating with a coupling nut (17) for axially moving the second sleeve component (9) relative to the first sleeve component (6) and for axially positioning the filling pipe (4) for connection thereof with the pipe connector (2), said coupling nut (17) cooperating with an external screwthread (19) on the pipe connector (2),(d) and an axially acting spring element being arranged between the sleeve components (6,
9) and imparting a biasing stress therebetween for maintaining the relative position of the sleeve components, whereby indication of the presence of a proper connection between the filling pipe (4) and the pipe connector (2) is derivable from the axial positions of the sleeve components (6,
9) relative to each other.

Abstract
A filling device for transportable containers and other suitable receptacles for the receipt of liquids, which facilitate a reliable and particularly feasible indication of faulty conditions encountered during operation in consideration of the handling thereof. A valve which closes off a filling tube of the container is actuated in dependence upon the connecting conditions of the filling device to the container; such as a tank container. When the filling device is not adequately coupled with an inlet pipe or any other device of the tank container, flow of liquid filling material cannot be initiated inasmuch as this flow is positively inhibited by the valve. Pursuant to another aspect, a vent or relief valve is automatically actuated in dependence upon the connected condition. The vent valve is also only first opened then when there has taken place a satisfactory or proper coupling with the respective tank container. This is of considerable significance for exhaust gas or, in essence, exhaust air removal installations, whose pipeline network continually stands under a certain subatmospheric pressure. Furthermore, there is a provision for an external display and plotting of a correct connection, as well for the operation of a sensor indicative of the filling condition which is present.
