Abstract (en)
[origin: WO03074843A1] The invention relates to a lightweight valve that consists of a valve base, the latter comprising a valve stem and a hollow valve cone, and a valve head cover, whereby the valve base is linked with the valve head cover by means of a material-displacing welding method. A weight-reducing cavity is defined between the valve cone and the valve head cover in the assembled state of the valve, said cavity being provided with a stability-enhancing support structure. Suitable welding methods are projection welding, capacitor discharge welding and friction welding.
