Abstract
A gas shuttle valve is for an internal combustion engine, in which a valve plate, as a sealing element, a tubular valve shaft, as a guide element, and a thrust part, which seals the end of the valve shaft opposite to the valve cone, as a stop for a valve operating element having a support for a typical valve spring, are welded to one another. This production method is distinguished by a precisely fitted assembling of these parts to a predetermined length measure, which precedes the permanent bonding of the valve shaft and thrust part.
