Constructive Description of the Hose Couplings for Tank Filling
摘要
The connection of the tanks with the vehicle tank has an outstanding importance, especially for the safety and for the quality of the product. The connection is made with a hose. At the interface between the hose and the tank is the coupling. This coupling must be used to reliably exclude the ingress of air. Natural gas contaminated with air can cause operating faults and restrict mixed condensation. This cannot be prevented with open refuelling systems.
