Abstract
An at least one spherical valve stem seat and a method for manufacturing the at least one spherical valve stem seat. The at least one spherical valve stem seat has a finished valve stem seat blank and a shell in retained communication therewith. The method for manufacturing the at least one spherical valve stem seat includes a molding process and an accompanying sintering, and machining process.
Claims20
A valve stem seat comprising:
- a blank and a shell in molded communication;
- said blank having a first section, a second section, a base assembly, and an extension;
- said base assembly having a first side and a second side opposite said first side, wherein said extension in communication with said first side;
- said first section in communication with said second side;
- said second section having a second section base;
- said second section base in communication with said first section, opposite said second side, wherein said communication provides for a lip;
- said shell having a shell first side and a shell second side, wherein said shell second side having a hemispherical geometry defining said valve stem seat;
- and
- said shell first side providing for a shelf, wherein communication of said lip and said shelf retains said shell in communication with said blank.

A method of manufacturing a valve stem seat comprising:
- positioning a first punch assembly in close proximity to a second punch assembly, wherein said second punch assembly comprises a punch and a collar;
- placing a blank on said punch;
- lowering said punch to a second position,
- wherein a relationship of said collar to said punch provides for a cavity;
- inserting resin into said cavity;
- lowering said first punch assembly, wherein said first punch assembly is in close proximity to said punch, wherein a shell is formed creating a stem seat head;
- removing said valve stem seat from said punch;
- sintering said valve stem seat, wherein a first dimension of a stem seat head is reduced to a second dimension;
- and
- machining a base assembly of said blank and said shell of said stem seat head, wherein an intersection of said base assembly and said shell provides for a profile finish.
