Also known by the initials DMF, Desiderio Martinez Feduchy. He made two radial engines: a 2-stroke and a 4-stroke.

-The two-stroke engine has already been presented in the DMF chapter, known by the name of "Dessy" and was a three-cylinder radial with its cylinders supported by the swinging cylinder head due to the rigidity of piston / rod assembly.

-It gave 25 CV and weighed 28 Kgs with the rods attached to the crankshaft like the Le-Rhone radial, that is to say with simple "heels" forming a sector.

"The 4-stroke radial"

-This 6-cylinder radial engine has sliding valves. See the patent illustration in the DMF chapter.

-It delivered 35 CV, with unit displacement of 80x80 mm.
