Abstract:
A camshaft rearranging device for an internal combustion engine including a crankshaft and a camshaft; said camshaft rearranging device comprising:(a) first means for fixed attachment to said camshaft so that rotation of said first means will cause said camshaft to rotate; said first means including a first means gear member having at least one spiral tooth; (b) second means for being rotated by said crankshaft; and (c) third means joining said first and second means to one another so that said first means will rotate when said second means is rotated by said crankshaft and for rotating said first means relative to said second means to rearrange the positional relationship of said camshaft relative to said crankshaft; said third means including a third means gear member having at least one spiral tooth for coacting with said spiral tooth of said first means gear member so that longitudinal movement of said third means gear member relative to said first means gear member will cause rotation of said first means gear member; said third means including a plurality of spaced apart male members, and said second means having a plurality of spaced apart female members for slidably receiving said male members of said third means to secure said second and third means together in a manner which allows longitudinal movement of said third means relative to said second means while preventing rotation of said third means relative to said second means.
