1. A side-channel machine, comprising
a housing;
a side channel located in the housing for conducting a gas;
at least one gas intake opening formed in the housing and having a flow connection to the side channel for conducting gas from the exterior the housing into the side channel;
a gas intake pipe coupled with the at least one gas intake opening, the gas intake pipe adjoining the side channel adjacent thereto for introduction of the gas into the side channel;
at least one gas discharge opening disposed in the housing for removing the gas from the side channel;
an impeller rotatable in the housing about a rotational axis, the impeller having impeller blades that delimit impeller cells disposed in the side channel for conveying gas located in the impeller cells in the side channel from the at least one gas intake opening to the at least one gas discharge opening;
at least one interrupter disposed between the at least one gas intake opening and the at least one gas discharge opening, to prevent gas from being transported from the at least one gas discharge opening to the at least one gas intake opening; and
at least one outlet channel disposed in the at least one interrupter downstream from the at least one gas intake opening and upstream from the at least one gas discharge opening for removing the gas enclosed in at least one of the impeller cells adjacent to the at least one outlet channel from the side channel into the at least one gas discharge opening.
