Wow, They had Roller Lifters and Rocker Arms way back then Hmmm where does the exhaust go, into the crank case where does the exhaust Exit, the valve is for fresh air and the cylinders have exhaust ports on the bottom.

The single valve was the exhaust but it also let in air.
The monosoupape (single valve) cycle although a 4 stroke has elements of a 2 stoke included in that the petrol was injected directly into the hollow but stationary crank shaft and cylinder transfer ports were used to get the very rich mixture above the piston. The exhaust valve stayed open well past TDC on the exhaust stroke so it introduced air into the cylinder to create a combustible (hopefully) mixture. Drawing air in via the exhaust valve also helped to cool it. Without high temperature steels burning exhaust valves was a real problem.
The monosoupape cycle was inefficient with a relatively high fuel consumption but the resulting engine was simple, light and for the time pretty reliable. It helped that Société Des Moteurs Gnome were excellent machinists making the entire engine from solid steel billets. .

The Le Rhône 9C "outline of re-assembly" video.
Based on the Le Rhône 80hp instruction book for re-assembling the Le Rhône 9C Aero engine. Manufactured by Société des Moteurs Le Rhône/Gnome et Rhône in France, Britain and Germany, this engine was fitted to a number of military aircraft types of the First World War.

An animated explanation about the inner workings of the Vickers Mk1 Machine Guns, mounted on the Sopwith Camel (HD). The Vickers Mk1l machine gun fired a .303 round at a rate of 500 rounds per minute. It was mounted on various aircraft and used by the British Army during WW1.

Given all the mechanical parts and cylinders are steel you can understand the weight but nevertheless a wonderful example of the machinists art. Just count up the number of ball bearings required!
