Abstract

The invention relates to a device for inductively heating the valve seat (12) of a machine part or of the cylinder head of an internal-combustion engine, using non-magnetic spacers (90) on the inductor (45), which abut against the valve seat (12) in order to set the required inductive coupling gap. Furthermore, to align the inductor with respect to the valve seat, a centring stud (86) is provided which moves in the valve stem hole (21) in the case of the feed movement of the inductor and thus provides concentricity between the valve seat (12) and the inductor (45) in conjunction with a spatially jointed coupling between the inductor (45) and the support (26), thus also allowing angular discrepancies with respect to the axis of the valve seat to be compensated for.
