Abstract: A gas jumper arrangement for a coke oven is composed of adjacently arranged coke oven chambers each having a gas opening with rims at the top portion thereof. The gas jumper arrangement overlaps gas openings of two adjacent coke oven chambers by one lid chamber each. The two lid chambers are connected in a duct-like manner by a gas jumper pipe and lids covering the gas openings during filling of a coke oven chamber are displaceable from an opened position into a closed position and settable into a rotational movement within the lid chambers by an actuation device. In order to ensure the tightness of the gas openings at the rims thereof even at larger pressure fluctuations and to enable the introduction of inert gas into the gas jumper arrangment, both the lid and the rim of each gas opening includes valve-face type sealing surfaces that mate with each other when pressed against each other in the closed position of the lid. A feed line for supplying an inert gas runs into the gas jumper arrangement.
