FILLING GASEOUS FUEL CONTAINERS WITH A TEMPERATURE AND PRESSURE CONTROLLED COMPRESSOR

摘要

A compressor (1) can be connected to a source of the gaseous fuel, in particular a natural-gas line (9), via a suction line (8) provided with an inlet valve (26) which can be shut off as well as to the gaseous-fuel reservoir (10) via a feed line (11) provided with a pressure-limiting valve (42) and a relief valve (43). The inlet valve (26) and the relief valve (43) are connected to a control device (50) which is arranged together with the pressure-limiting valve (42), the relief valve (43) and if need be the inlet valve (26) in a pressure-proof housing (6) which is attached to a discharge line (20) leading away from the device. The control device (50) can be influenced as a function of control signals from a temperature sensor (58) detecting the ambient temperature and from a pressure sensor (41) detecting the feed pressure of the compressor (1) and also from a pressure-differential sensor (25) which is arranged upstream of the inlet valve (26) and detects the difference between the pressure prevailing in the suction line (8) and the pressure prevailing in the housing (6). ……
