  • Patent number: 11781559
    Abstract: A side channel compressor for compressing gas includes a housing, which forms a side channel, and an impeller drive arranged in the housing. The housing forms a feed channel fluidically connected to the side channel for feeding gas to the side channel and a discharge channel for discharging gas out of the side channel that is fluidically connected to the side channel. The feed channel branches into two separate channel arms each extending along a channel arm center axis. The housing is subdivided along a separating plane into first and second housing parts which sealingly lie against one another. The discharge channel is passed through between the two channel arms and either a first or second discharge channel part of the discharge channel, opens out on a connecting surface of the first or second housing part forming a gas outlet opening arranged apart from the separating plane.
