Continuously Variable Hydrostatic Cam Follower Motor or Pump
Small Entity U.S. Provisional Patent Application #61/209,633 filed: 3/9/2009
Continuously variable hydrostatic transmission systems are now available options for passenger automotive vehicles and trucks and the advantages are now well advertised. However, before they became common options, I explored my own designs for this solution. Perhaps my most novel design is a cam-follower with the cams actuated by hydrostatic cylinders. A possible advantage of this design would be ease of maintenance due to the accessibility of moving parts.
Since I have abandoned the patent, I am now publishing my cam-follower motor drawings should anyone be interested. Remember that the text has not been updated recently. Send me an email if you find it interesting.
