ABSTRACT:
A compressor (1) can be connected on the suction side via a suction line (7) provided with an inlet valve (16) to a natural gas line (9) and on the pressure side via an intake line (12) to the gas fuel tank (13) and is also connected via a relief line (10) to a relief valve (11) and a pressure control valve. (25), with said valves being disposed in a pressurized tank (4). This tank is connected to the suction side of the compressor (1) and the outlet sides of the inlet valve (16) and of the relief valve (11) and also with an outlet line (18) via a safety valve (20), which can be set at a predetermined opening pressure of 2 to 3 bar, for example. The pressurized tank (4), is designed with a cover (5) constructed as a support part, on which the compressor (1) is mounted. The compressor (1) can be coupled via a vertical drive shaft (2) with a motor (3) disposed inside the pressurized tank (4). This arrangement permits a simple design of the pressurized tank (4) and a compact construction of ,the appliance, which is particularly intended for refueling motor vehicles.
