Abstract
The present invention pertains to arrangements for a pre-chamber of a combustion engine as well as pre-chambers comprising such arrangements, in particular to condition or temper a gas flow within a gas-purged pre-chamber prior to entering a combustion area. Accordingly, an arrangement for a pre-chamber gas valve of a combustion engine is suggested, comprising a housing having an outer surface and comprising a channel, a first end of the channel being in fluid communication with the outer surface and a second end of the channel being connectable to a valve seat of the pre-chamber gas valve, and at least one protrusion extending from the outer surface of the housing. The first end of the channel is arranged upstream of the second end of the channel and downstream of at least one protrusion, wherein the arrangement is configured to absorb heat from a combustion portion of the combustion engine arranged downstream of the second end and to temper a gas upstream of the second end only using said heat, when the arrangement is in a mounted state.
