Benefits of technology

The invention provides a filler neck that avoids breaking joints and leaks, is easy to install and reduces pressure drop during filling. The filler neck comprises a rotary device for easy fixing and a curved tube for improved fluid flow. The new design also allows for easy filling of fluid systems due to improved fluid flow. Overall, the filler neck simplifies installation and reduces costs.

Problems solved by technology

Additionally, a high risk exists of debris from spin welding process of caps.
The debris can cause breaking off from joint which can lead to an engine or water pump damage.

Embodiment Construction

[0016]The figure shows a first embodiment of the filler neck 1 according to the invention. Such a filler neck 1 is used by filling a fluid system with fluid. Such fluid systems are especially radiator assemblies or engine coolant systems, which are filled with a coolant.

[0017]The filler neck 1 includes a filler tube 2 and a filler beginning 3. The filler tube 2 is arranged on the fluid system 4 wherein the filler tube 2 is curved. Hence, the filler beginning 3, which is designed at the filler tube 2 opponent to the fluid system 4, is directed perpendicularly to an opening of the fluid system 4 not depicted in addition. Laterally, a flanged socket 5 extends to the filler beginning 3. The diameter of the filler beginning 3 is larger as the diameter of the filler tube 2.

[0018]The whole filler neck 1 comprises the filler tube 2, the filler beginning 3 and the flanged socket 5 and is fabricated as one piece. Advantageously, the filler neck is formed of plastic material. The filler neck 1...

Abstract

A filler neck for filling a fluid system, especially for filling a radiator assembly or an engine coolant system is provided. The filler neck avoids breaking of joints and waiving of leak tests by a filler tube and a filler beginning connected with the filler tube.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention refers to a filler neck for filling a fluid system, especially for filling a radiator assembly or an engine coolant system.[0003]2. Description of the Background Art[0004]After fabrication of radiator assemblies or engine coolant systems a cooling fluid is brought into the radiator assembly or the engine coolant system. Hence, a filler neck is necessary to fill the fluid into the radiator assembly or the engine coolant system. The filler neck is arranged in an opening of the radiator assembly or the engine coolant system. The filler neck comprises a spin welded cap or a plug to seal an end of port for cantilevered filler necks.[0005]Spin weld of caps or plugs to seal end of port require secondary operation for leak tests. Additionally, a high risk exists of debris from spin welding process of caps. The debris can cause breaking off from joint which can lead to an engine or water pump damage.SUMMARY OF THE ...
