Arrangement for the metering of fuel, in particular liquid gas, to a variable-output consumer, which comprises a metering device with a reduction valve (4), a metering valve (11) and a chamber (20, 21) arranged therebetween, as well as means of control or regulation for the setting of the valves as a function of operating variables, in particular for controlling the metering valve (11) as a function of a power requirement signal. For the purpose of high precision metering which is suitable even for the requirements of a lambda control, the arrangement is made such that the means of regulation act on the setting of the reduction valve (4), the chambers (20, 21) between the two valves being designed as a buffer volume for the equalization of pressure fluctuations. A metering device for this arrangement is characterized for the purposes of variable use by two separate housing parts, one of which, as chamber housing part (30), forms the buffer volume or is essential for heat transmission, while the other, as mechanics housing part (29), accommodates the reduction valve (4) and its actuation mechanism.
