Fuel tank having installations and method for the production thereof
A fuel tank that is composed of plastic and that has installations. In order to functionally improve the fuel tank and to simplify the manufacturing, a shaped piece (15) is attached to the inside of the wall (1) of the fuel tank and connected to the fuel tank in a bonded manner. The shaped piece (15) is a flat component that has an open three-dimensional shape and forms at least one channel (17) and/or tank together with the plastic shell (1). The shaped piece (15) is welded all around to the plastic shell (1), wherein a welding flange (20) forming a closed curve follows the contour of the channel (17). The shaped piece (15) has at least one mouth part (16) that is open toward the tank interior and is integral with the shaped piece.
A fuel tank made of plastic, in the interior of which an insert (2) is located, wherein the insert should enclose a space (3), wherein the fuel tank should offer the greatest possible economy of space, and the fuel tank and the insert should have a simple form. For this purpose, a box made of plastic and open at the top is attached to the inside of the upper wall (1) of the fuel tank as an insert (2), wherein the box forms a closed space (3) together with the wall (1) of the tank, wherein the insert (2) comprises a bottom (5) and side walls (6, 7, 8, 9), the upper edges of which are connected in a bonded manner to the wall (1) of the tank. The insert (2) contains inner parts (20-26) that are integral therewith and has at least one fitting (13-16) on the side walls (6, 7, 8, 9) for connecting a pipe line.
A fuel container, which is operated at positive pressure and consists of two shells (2, 3), is to be reinforced by way of an internal column (6) such that a connection ensuring tensile strength is created when the two shells (2, 3) are joined. To this end, the column (6) has a first (7) and a second (8) part connected to the respective shell, one part (7) has detents and the other part (8) has detent hooks (26), which create a snap-fit connection ensuring tensile strength when joined. For this purpose, the two parts comprise detent surfaces (18, 34) and deflection surfaces (19, 35), and the detent hook (26) can be elastically displaced.

A coupling device (22-28) is arranged between the cover body (6) and the cover (14) and, during the positive pressure which prevails in the fuel tank during normal operation, releases the rotational connection between the cover body (6) and the cover (14) such that the fuel tank cannot be opened, and in that a pressure control valve (40) is provided which opens when the positive pressure prevailing during normal operation is exceeded.
In a tank system, a venting line (6) connects the fuel tank to an activated carbon filter, and a recirculating line (10) opens into a filler head (3). In order to prevent the penetration of liquid fuel into the activated carbon filter, to permit the seal to be checked by applying a partial vacuum and to provide a filler head which can be manufactured inexpensively, an insertion body (22) is provided which forms a funnel (23) which is adjoined by a neck (24) which accommodates the fuel nozzle, which insertion body (22) has, in addition to the neck (24), two vertical blind holes (31, 32), open at the bottom, and a transverse duct (33) which connects the latter, wherein the first blind hole (31) is connected to the recirculating line (10), and a float (40), which clears or closes off the connection to the transverse duct (33), is guided in the second blind hole (32).
The invention relates to a fuel tank made of plastic, in the interior of which an insert (2) is located, wherein the insert should enclose a space (3), wherein the fuel tank should offer the greatest possible economy of space, and the fuel tank and the insert should have a simple form. For this purpose, a box made of plastic and open at the top is attached to the inside of the upper wall (1) of the fuel tank as an insert (2), wherein the box forms a closed space (3) together with the wall (1) of the tank, wherein the insert (2) comprises a bottom (5) and side walls (6, 7, 8, 9), the upper edges of which are connected in a bonded manner to the wall (1) of the tank. The insert (2) contains inner parts (20-26) that are integral therewith and has at least one fitting (13-16) on the side walls (6, 7, 8, 9) for connecting a pipe line.
