Abstract (en)
[origin: EP1193375A1] Valve, preferably for an internal combustion engine, comprises a valve shaft (2), a valve cone (3), and a valve disk (4). The valve cone has a recess (3a) for receiving the valve disk, and the valve cone and the valve disk together form a hollow chamber. The valve disk has a smaller diameter than the recess in the valve cone so that an insulating gap (6) is produced between the recess in the valve cone and the edge (4a) of the valve disk. Preferred Features: An annular shoulder (3b) is arranged in the recess of the valve cone and supports the valve disk in the direction of the valve axis.
