Abstract (en)

[origin: DE19757117A1] A cylindrical valve seat body (25) is manufactured and a passage (32) is formed in it with an intake/ opening section (47,48), a guide section (31), and a valve seat section (26). The valve seat section is a truncated cone-shaped part of the passage. The guide section has alternating web-like guide parts (51) and channel-like flow passages (27). All guide parts are simultaniously finished via a tool consisting of a master ball (130). A raised valve seat (26') is formed on the valve seat section.
