1 lunger diesel with adjustable pitch prop

I saw a pic of an old 1 cylinder diesel with an adjustable pitch prop.Anyone know of a manufacture of these?The engine appeared to be from the 1920's or 30's.

 

I think Sabb and Bukh made them in the 60's.

Thanks.I'm considering 1 or 2 units,if I can find a matching pair,for a project I wanna build.Are the props manually adjustable on the go or oil pressure operated like an aircraft prop?

 

Hollow shafts and inner shafts move the gear to change the pitch

 

Ahhhhh.Now I understand how it works.Shaft in shaft set up.

 

HUNDESTED INVENTED THEM I BELIEVE BUT WHAT ARE THEIR SMALLEST ENGINES, I DONT KNOW, NO NEED FOR A GEARBOX

 

Hundested did not invent them, but make a very good quality CPP. Although not in that power range! Gori is the brand for such a small application.
But you know that these engines you mentioned (SABB & BUKH) have a weight between 300 and 500 kg?

thank you for correcting me, how do you rate Gori engines & sterngear

 

Gori does´nt make engines.
The props are very good and reliable.

 

these are folding props, are there any CPP for smaller craft

 

I think they still make a 4 blade CPP (not folding).

And here we have another manufacturer of small CPPs:
