Housing for a tank connection fitting

The innovation concerns a housing for a tank valve, which can be screwed onto the opening of a handle and with at least one connection piece for a suction line, a connection for a return line and with is provided with a built-in non-return or quick-closing valve.

from contamination it is necessary to dismantle a number of individual parts, which is associated with great effort. In addition, in many cases it is also necessary to loosen the connection fitting from the tank opening, so that afterwards again an adjustment of the supply lines and all individual parts is necessary so that the tightness of the arrangement is guaranteed.

The present innovation is based on the object of designing a housing for a tank connection fitting of the type mentioned at the outset in such a way that the interior of the housing is readily accessible and that, in addition, necessary adjustment work during assembly is not impaired.

The innovation is that at least three housing parts are provided, of which the middle is essentially zy cylinder-shaped and from a cover part inserted into it on the top in the direction of the cylinder axis and on the underside by a screw pin pushed in the axial direction for screwing into the Tank opening thread is complete. This configuration enables a very simple production of the parts, in particular from plastic, for example, it is also possible to produce different housings for tank connection fittings in a relatively simple way when combining different cover parts with the middle housing part or when combining different screw connections.

It is useful if the cover part is guided in the middle housing part with a cylindrical approach and is held on the housing part by a union nut which is screwed onto an external thread of the housing part, because then it is possible to loosen the cover part and thus expose the inside of the housing without the aid of tools, without the tightness is impaired.

In this embodiment, the valve and the check valve can be installed in a cylindrical guide which is pushed into a cylindrical guide adjacent to the suction line fastened in the housing part. Despite the arrangement of these check valve parts, no other, more complex assembly is necessary.

The screw socket can in turn be pushed onto a cylindrical extension on the underside of the housing middle part and held exclusively by a ring arranged in circumferential grooves of both parts. This version has, apart from manufacturing and assembly-related simplifications , the advantage that the housing means can be rotated part on the screw socket , so that in a very simple manner an adjustment of the position of the housing middle part with the connection piece to the laid supply and discharge lines is possible. It is possible to make this retaining ring made of elastic material , so that a decrease is also possible afterwards Lich. For f estigkeitsteohniechen reasons it is more useful if the ring is made of injected plastic, which then, if the other housing parts are made of plastic , must have a lower melting point than the other plastic housing parts.

The middle part of the housing is made of transparent plastic

produced, it is also possible to simply observe the inner arranged part including the oil passage.

In the drawing, the innovation is shown on the basis of an exemplary embodiment and in the following Besohreibuag explained. Show:

In the l ^? ig. 1 and 2, within a housing part 1 made of plastic, several chambers are formed by cylindrical inserts 2 and 3 and by the arrangement of an Ifückschlagvenfciles 5 seated on a guide pin 4 firmly connected to the housing 1, of which the one in the insert 2 located chamber forms a suction chamber 6 ″, which is connected to the connecting piece 9 via a check valve 7. This suction line 9 leads to a pump, not shown, which is to supply the combustion points of a heating system with fuel the connection piece 11, which opens into a ventilation space 1? in which the insert 3 is arranged.

the threaded connector 18 is screwed onto the opening stub is, in which a cylindrical extension 1a of the housing part 1 is held axially fixed but rotatable. That happens in that both in the approach 1a, and in the cylindrical inner wall of the threaded connection piece 18 Grooves 1b and 18a are arranged, which are filled by a retaining ring 28b. This retaining ring 28b can be made from the assembly of parts 1a and 18 consist of injected plastic, the melting point of which must be lower, than that of the plastic from which parts 1a and 18 are made.

The housing part 1, which can consist of transparent plastic, also has a connecting piece 19 to which a connecting line 20 is attached, which leads to another tank that is connected to the tank on which the nozzle 18 is unscrewed, is combined into a battery tank system. Further tanks can also be connected to line 20 in Be connected in series.

The housing part 1 is closed at the top by a cover part 21, in which the seat for the check valve 7 is arranged and in which there is also a mechanical quick-action closing device 22 is arranged for the valve 7, which ensures a closure of the suction line in the event of danger. A limit value transmitter can also be passed through the cover part 21. The cover part 21 is from above on the Housing part 1 put on, engages with cylindrical lugs 23 or 24 in the corresponding inserts 2 or in the upper one Edge of the housing part 1 and is sealed there by seals. The cover part 21 is secured by a union nut 25 held on the housing part 1. In this way it is guaranteed that very quickly and easily the housing part 1 can be opened v / ground, for example to remove impurities or the like. remove or replace the breather filter 14.
