Pre-combustion chamber apparatus and method for pre-combustion

Abstract

The present invention uses an improved engineered metal seal with or without an internal energized spring that is disposed in a pre-combustion chamber apparatus assembly to improve sealing over the flat washer seals that are currently used. The seals of the present invention comprise at least three different geometrical configurations of seals that are manufactured from titanium, Inconel, and/or hastelloy. The design of the tip and body of the pre-combustion chamber provide for movement of the seal without leaking. The sealing is provided on the axial surfaces of the tip and the body instead of the face of the tip and body by a flat washer seal, as is currently done.

What is claimed is: 
     
         1 . A pre-combustion chamber assembly comprising:
 a body shaft;   a tip;   a seal disposed on axial surfaces of said tip and said body shaft;   and a groove disposed in said body shaft.   
     
     
         2 . The seal of  claim 1  wherein said seal comprises an engineered metal seal. 
     
     
         3 . The seal of  claim 1  wherein said seal comprises an engineered metal seal with an energized spring. 
     
     
         4 . The seal of  claim 1  wherein said seal comprises a face style engineered metal seal and an energized spring. 
     
     
         5 . The groove of  claim 1  wherein said the disposition of said groove orients said tip. 
     
     
         6 . The engineered metal seal of  claim 1  wherein said seal comprises a material including Inconel, hastelloy, or titanium alloys. 
     
     
         7 . The body shaft of  claim 1  wherein the diameter of said body shaft comprises a plurality of tapers. 
     
     
         8 . A method for sealing pre-combustion chamber assembly comprising:
 disposing a groove in a pre-combustion chamber;   inserting a seal comprising an engineered metal seal in the groove; and   improving the geometry and tolerances of the ignition pre-chamber.   
     
     
         8 . The method of  claim 8  comprising disposing the seal against the radial surface of the body shaft and the tip. 
     
     
         9 . The method of  claim 8  further aligning and seating the seal. 
     
     
         10 . The method of  claim 8  wherein aligning the seal comprises disposing an engineered metal seal along the body shaft wherein the body shaft comprises increasing diameters by providing tapered sections. 
     
     
         11 . The method of sealing of  claim 8  comprising aligning and seating the seal. 
     
     
         12 . The method of sealing of  claim 8  further comprising expanding the seal against the body shaft, increasing the pressure of the seal at one face of the body shaft, and increasing sealing properties.
