Claims

exact text as granted — not AI-modified
1 . A valve spring retainer comprising:
 a base having an outer periphery and a central aperture, said central aperture defining a center axis; and   at least two tabs extending radially from said base outer periphery relative to said center axis, each of said tabs having a distal end including an axially extending lip for retaining a spring relative to said retainer.   
   
   
       2 . The valve spring retainer as in  claim 1 , in which said central aperture is formed in a downwardly extending tapered cone section. 
   
   
       3 . The valve spring retainer as in  claim 2 , in which said central aperture is surrounded by an upwardly extending annular ridge. 
   
   
       4 . The valve spring retainer as in  claim 1 , including a reinforcing band surrounding said cone section. 
   
   
       5 . A valve spring retainer comprising:
 a base having an outer periphery and a central aperture, said central aperture defining a center axis;   a downwardly extending tapered cone section coaxial with said central axis; and   at least two tabs extending radially from said base outer periphery relative to said center axis, each of said tabs having a distal end including an axially extending lip for retaining a spring relative to said retainer.   
   
   
       6 . The valve spring retainer as in  claim 5 , including an upwardly extending annular ridge surrounding said central aperture. 
   
   
       7 . The valve spring retainer as in  claim 5 , including a reinforcing band surrounding said cone section.
