  • Patent number: 4858583
    Abstract: 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.
