Abstract: 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.

CPC classification number: E21C35/197
Abstract: An indexable earth cutting tool system includes an indexable earth cutting tool assembly and a support block. The earth cutting tool assembly includes a cutting tool, such as a conical cutting bit, and a sleeve having a bore for receiving a shank of the conical cutting bit. The conical cutting bit can be a rotatable conical cutting bit or a static conical cutting bit. In one aspect, the sleeve is a dual indexable sleeve with the bore having a cylindrical portion and a non-cylindrical portion that accepts both the rotatable conical cutting bit and the static (i.e., non-rotatable) conical cutting bit. In another aspect, the sleeve is a static indexable sleeve with the bore having only a non-cylindrical cross section that only accepts the static conical cutting bit.
