Abstract
A refuelling equipment (7) may be connected via an adjustable loading valve (30) to three groups of intermediate stores (4, 5, 6) in which natural gas is stored at different storage pressures. The loading valve (30) contains three inlets, each of which is connected via a feedline (13a, 14a or 15a respectively) to one of the intermediate stores (4, 5 or 6 respectively), and one outlet which is connected via an outlet line (24) to the refuelling equipment (7). The loading valve (30) further contains a cyclically adjustable valve body (31) which may be switched respectively from a first blocking position blocking all of the inlets, into a first flow position connecting the supply line (13a) to the outlet line (24), past a second blocking position into a second flow position connecting the supply line (14a) to the outlet line (24) and past a third blocking position into a third flow position connecting the supply line (15a) to the outlet line (24) and finally in the same direction of rotation back into the first blocking position. During each refuelling process the refuelling equipment (7) is accordingly directly connected first to the intermediate store at the lowest storage pressure, then to the intermediate store (5) at the middle storage pressure and finally to the intermediate store (6) at the highest storage pressure.
