A device suitable for supplying a gaseous fuel to an internal combustion engine having combustion chambers includes an evaporator with a metering device, the metering device on an inlet side being in communication with an evaporating chamber disposed within the evaporator, and on an outlet side being provided with a main pipe, the main pipe downstream from the metering device branching into a number of pipes connected to individual combustion chambers. Each pipe is provided with a fixed predetermined local constriction, across which at least 85% of the pressure drop from the division of the main pipe into the individual pipes to the combustion chambers takes place, whereby the differences in the flow resistances of the local constrictions of the individual pipes are 5% at most.

[ What is claimed is:] [1.] A device (1) suitable for supplying a gaseous fuel to an internal combustion engine comprising combustion chambers, which device is provided with an evaporator (3) and with a metering device (5), said metering device (5) on an inlet side (32) being in communication with an evaporating chamber (13) disposed within said evaporator (3), and said metering device on an outlet side (33) being provided with a main pipe, said main pipe after said metering device (5) branching into a number of pipes (63) connected to the individual combustion chambers, characterized in that each pipe (63) is provided with a fixed predetermined local constriction (65), each said fixed local constriction being physically formed in said pipe to provide a non-variable, fixed, similar constriction in each said pipe, across which at least 85% of the pressure drop from the division of the main pipe into the individual pipes (63) to the combustion chambers takes place, whereby the differences in the flow resistances of the local constriction (65) of the individual pipes (63) are 5% at most, wherein the outlet side of the metering device (5) is connected to a pressure regulating chamber (17) disposed within the evaporator (3), which pressure regulating chamber (17) is separated from the evaporating chamber (13) by a movable membrane (19), whereby the supply of liquid gas to the evaporating chamber (13) is able to be regulated by means of said membrane (19).
