Abstract: Reservoirs for fuel tanks, which can be filled via an opening that can be closed by a closing element, are already known. Such a closing element interacts with a sealing seat and is arranged on a bearing that is located in the region of the opening and is fixed to an edge area of the opening by at least two struts. In prior art, the opening, with the bearing and the struts, is often produced as a single-piece together with the reservoir and the base by injection molding. A disadvantage thereof is that the struts can undergo material shrinkage during production, which leads to a tension of the struts between the edge area of the opening and the bearing. This can lead to an irregular deformation and hence to an uneven sealing seat, so that the closing element does not seal in a tight manner and that the valve has a leak. in the reservoir according to the invention, the sealing of the opening is improved by at least one strut not having a rectilinear form, thus obtaining elastic expansion compensation.

Abstract: The present invention includes a device that comprises a suction jet pump, that is arranged in a reservoir pot and has a nozzle and a mixing duct provided downstream the nozzle and arranged perpendicular to a pot base of the reservoir pot. The outlet of the mixing duct has a deflection means, which the jet of the nozzle impinges when the mixing duct is unfilled and has an additional volume formed at the outlet of the mixer by an offset widening of the mixer duct. This additional volume prevents the column of liquid in the mixing duct from being forced out by the propulsion jet of the suction jet pump. Thus the lead time of the suction jet pump is approximately equal in all operating states.

Abstract: Holding elements are known for holding an assembly in a holder, comprising a holding section for engaging behind the assembly and holding members that are provided on the holding section for holding the assembly in the holder. It is disadvantageous that the holding element is comparatively expensive to produce. For example, it is configured very rigidly in the holding direction, which is achieved with a comparatively high amount of material. This results in high production costs. In addition, in the case of very high mechanical loads the detent connection can detach due to torque acting on the detent hooks. The holding element according to the invention is simplified, thereby lowering the production costs. According to the invention, the holding section has a flat configuration viewed in the holding direction, and the holding members are angled in relation to the holding section and configured as elastically resilient holding arms.

Abstract: Fuel delivery modules are already known having a tank flange and having an accumulator pot which is connected to the tank flange by means of at least one guide rod and which is mounted so as to be axially movable along the guide rod, where the guide rod is pressed with one end into a receptacle of the tank flange. It is disadvantageous that the receptacle is expanded over the entire longitudinal extent as the guide rod is pressed in. As a result of tolerance fluctuations in production, excessively high pressures can occur in the receptacle here, which pressures can cause cracks in the receptacle. This leads to rejects and therefore to high production costs. In the fuel delivery module according to the invention, damage to the receptacle during assembly is prevented.

Abstract: Devices for supplying fuel are already known, having a supply unit which has a pump housing connected to an electrical ground and is supported on a pump mount. It is disadvantageous that during operation, the pump mount can become electrostatically charged and has no device for electrostatic discharging during operation. The invention provides an especially simple and economical grounding device for the pump mount. In particular, a charge diverter is connected to the pump housing via a grounding element, and contacts a surface of the pump mount.

Abstract: Devices for delivering fuel are already known, comprising a suction jet pump that is arranged in a storage crucible and has a nozzle and a mixer duct provided downstream of the nozzle and arranged perpendicular to the bottom of the storage crucible, wherein at the outlet of the mixer duct an impingement means is arranged, against which the jet of the nozzle impinges in the substantially unfilled mixer duct, and in doing so is at least partially returned into the mixer duct. It has been found that despite the impingement means the propulsive jet tends to eject the liquid column present in the mixer duct. As soon as the liquid level in the storage crucible has decreased below the outlet of the mixer duct, no more fuel can replenish from above into the mixer duct so that the mixer duct may be unfilled after switching off the suction jet pump.
