There is also a Marchetti brand known in Italy for the manufacture of aircraft.

-But here is "Marchetti Motor Patents, Inc" that was based in the Russ Building in San Francisco, California and that offered a radial engine with no crankshaft, but with a double cam, as we see in the below photo.

"8-cylinder Marchetti"

From Appendix A6/6: We have a nice drawing showing the cam and linkage mechanism of this Marchetti Cam type engine.

-The drawing is by Mr. Bill Todd and there is an animated version.

“Cam Engine Mechanism Diagram”

-The prototype was built in 1927, it gave 175 HP.

From Appendix 12: Here are two designs from cam-action engine patents, a W-engine and an in-line.

“W-engine”

“In-line engine”

-As for the known radial engines of 10 and 6 cylinders there are new illustrations.

“Marchetti 10-cylinder, double row, radial“

“Marchetti 6-cylinder schematics”

-To the left the Nordwick (see Nordwick Engine Company) and the Marchetti to the right.

-We found a patent for this American brand that uses a cam system instead of a crankshaft.
