Abstract

The gas distributor apparatus has a common gas-supply line for supplying gas to a plurality of devices, e.g., arranged in series, the gas-supply line representing a substructure with an inner supply orifice and connecting pieces, which conform in number to the devices for injecting a fuel-gas mixture, and which extend in a normal direction starting from the gas-supply line and contain branched-off ports that communicate directly with the supply orifice. A permanent connection is established between the gas distributor apparatus and the devices in that gas-intake ducts are configured on the gas-containing bodies at least partially surrounding the devices, the gas-intake ducts having functional elements and projecting with these elements into the connecting pieces of the gas distributor apparatus. The gas is made available simultaneously for all devices in the supply orifice and then flows in each case via one connecting piece to a device. Thus, the gas distributor device represents a very compact assembly, which is very simple to assemble and disassemble. The gas distributor device is especially suited for fuel-injection systems of mixture-compressing internal combustion engines hav…
