The invention relates to an arrangement of a pump in a fuel tank for refueling and defueling, especially for combat vehicles. wherein the pump has a pressure pipe connected to the pump motor, in which a pump rotor is arranged at the free end.

There are known fuel pumps which are permanently installed at the bottom of the fuel tank. In the event of a fault or failure of the pump, it is only _{accessible for 4S} when the container has been emptied. Such a pump is designed for one use only, ie for permanent installation in the container.

In contrast, the invention has for its object to provide a pump arrangement that the optional installation in a motor vehicle tank to supply an engine and as a separate refueling unit enables.

This object is achieved according to the invention in that the pump can be _{fastened via closure means either in a 5S} opening of a container wall as a stationary motor vehicle / eugförderpump and is designed as a freely movable refueling unit which can be detached from the container.

With the optional pump arrangement according to the invention, it is advantageously achieved that the pump can be quickly removed from a fuel tank by means of the closure means. This is necessary if the pump is defective or to refuel a vehicle from a container or barrel. llic / u _; , _s becomes z. B. introduced the pump into the filled container of another vehicle and carried out a refueling or defueling. Carrying an additional

There is therefore no need for a small refueling and defueling pump.

An advantageous development of the erfindungsge A moderate pump arrangement consists in the fact that the pump is provided with an annular flange on the circumference of the housing. which looks up on a container-side outer ring flange and both flanges from a V-shaped Closure tape are firmly gripped.

This is achieved in an advantageous manner that the Pump without emptying the container through provided and easily accessible outside of the container Holding and locking means is detachable from the fuel tank.

Furthermore, it is provided according to the invention that the Pump for Bc- and defueling has a connecting piece arranged outside the container, which is designed as a connection for a Schnelltrcnnkupplung. A hose is attached to the connecting piece. It is also provided that the pressure pipe of the pump extends to the bottom of the container and on has one or more inlet slits free end of the pressure pipe.

An embodiment of the invention is shown in the drawing and will be described in more detail below described. It shows

Fig. 1 is a view of the in a fuel tank stationarily arranged pump and

Fig. 2 is a view of the pump when used as a separate refueling unit.

The pump 1 consists of a pump motor 12. a rotor shaft 1.} mounted in the pressure tube 9, which is shown in a bearing tube 14 is arranged, and a pump motor 15 mounted on the free end of the rotor shaft 13.

The pump I is at the top of the fuel tank attached, and the pressure pipe 9 extends f; isi his to the bottom IO of the container. That close above that Container bottom 10 arranged free end of the pressure tube 9 has one or more Kinlaßschlitzc ί I on. Via the pressure pipe 9 and pump channels 16, the fuel is transferred from the container to an outside of the Container on the pump housing provided connection port 8 passed. The connecting piece 8 white one quick disconnect coupling, not shown, for a hose, a line or the like.

The definition of the pump 1 on the fuel tank takes place via a quick-release fastener 2 which positively engages an annular flange 6 standing on the annular flange 7 of the fuel tank on the pump housing. The well-known per se Schnellvcrschluß besteh 2) consists of a V-shaped metal strip, comprising the flange is annular and UEBC ^r Schraubmitlei not shown is tightened.

To ^r use of the injector I as a separate refueling unit (Fig. 2) of the Schnellvcrschluß 2 is released, and the entire Pumpcncinheit 8 are used to 15 can immediately without complicated conversion as separate refueling unit and an I or 7. B. ate a fuel tank of a can be plugged into another vehicle and thus filling and defuelling can be carried out via a hose. This eliminates the need to carry an additional refueling pump. The screw socket 17 of the barrel or the like does not have to be a guide for the pump I. The operator holds the pump 1 on the motor so that he can switch off at any time.

Dpi- Ryinr! 5 in the pressure pipe 9 is at the fixed Arrangement of the pump 1 in the fuel tank just above the bottom IO of the tank. In this Operating condition is only a small amount (18 l / min)

with about I aiii back pressure promoted. With the use of the pump I as a separate fueling unit, it is possible to refuel for a week. 100 l / min at about 0.J atm. For this purpose, the engine 12 can be switched to two speeds .

For this purpose 2 sheets
