Hi!: merry Xmas and happy new year 2017 to all.

   I've found in my files these old documents about the ways a two-rotor unit had the cooling liquid flow arranged, they say that the rear rotor is always a bit hotter, but I don't know much about the connection of this hot zone to the site or way liquid flow enters the housings.

   Has anyone experience with the proposal in the Max Bentele patent nº 3.007.460 of Nov 7, 1961, or alternative arrangements? Comments?

   Thanks, best regards, + Salut

   Good work Jose. Thanks.

   Yes! I and others have been aware of that problem for years and it is a worse problem on the 3 and 4 rotor
   engines. We have considered re plumbing the cooling system in the engine and using an external cold water gallery.

Paul, Jose,
On their "Superlight" engine Steve Beckham and Everett Hatch plumed the water into the mid plate directly ajacent to the hot area. They flowed inside to outside with 2 exits. This worked very well. (on the 2 rotor) the parallel idea shown would be good on 3 or more rotor engines.
