Twin steam engine OKW-DV6
« on: May 04, 2023, 01:37:40 PM »
The OKW-DV6 is a vertical twin steam engine. The valve chests with the sliding valves are arranged alongside the cylinders and not as typically in inline arrangement.


The reversing valve gear is of the type “Klug”- or “Joy”-valve gear. The Joy valve gear needs only one eccentric per cylinder different to Stephenson´s valve gear who uses two eccentrics.
The Joy valve gear typically uses several connecting rods in its design, the model design is modified by using a T-slot slider lever. The T-slot is milled in on both sides of the drum which swings via a lever for reversing action


The model drives a boiler feed pump via a bevel gear drive.


The cylinders are equipped with a drain station.


The arrangement with the valve chests alongside the cylinders results in a very compact engine with a short overall length. For that reason this kind of original engine was a favored prime mover in small river tugs.
The model is very strong. You can hardly slow down the engine braking the flywheel with your hand.
The model is build from scratch using a set of drawings.
Technical data:
Stroke:     18mm
Piston diameter:        16mm

Beautiful engine and a wonderful job of building it?

Can I ask if this is your own design?  If so, that's very impressive!

Hello Mike,
thank you, I appreciate your comments. Yes it is really a nice engine.

I build it from plans which I purchased from the designer. He is a German designer and his name is Otto K. Weller. From his initials he took the type name of the engine OKW - DV6.
The drawings were done in 1993 but fortunately they are ongoing available in an online shop:
