Beschreibung
Zusammenfassung:	A valve seat assembly includes a body having an insert pocket with an axially extending inner surface and a radially extending bottom surface. The valve seat further includes an insert disposed within the insert pocket of the body. The insert includes an axially extending outer surface and a radially extending bottom surface for mating with the axially extending inner surface and a radially extending bottom surface of the insert pocket of the body. The axially extending inner surface of the body is formed with a non-zero reverse taper angle, A4, for securing the insert within the insert pocket of the body. The axially extending outer surface of the insert is formed with a reverse taper angle, A5, equal to or greater than zero degrees. A valve assembly includes a valve and the valve seat assembly in reciprocating contact with the valve.
