The Le Rhone rotary has one push/pull rod that runs along the back (outside) of the cylinder. The rod is connected to an arm that actuates a "jackshaft" to a "T" rocker arm. The exhaust valve is actuated on the push and the intake is actuated on the pull. The intake that runs along the side of the cylinder carries the fuel/air /caster oil mixture from the crankcase (drawn in on the intake stroke of piston). Remember the tubes protruding from the sides of the fuselage are intakes. Then compression; then power; then rod pushes on exhaust stroke (as mentioned by others rotary engines expel their exhaust out the top of the cylinder-timed so that it takes place when cylinder is entering bottom of rotation). 4-stroke not 2. The Clerget is similar but with separate push rods at the front and the intake is at the back of the cylinder. If you take a look at the Le Rhone engine on the Bristol M1.C at Mr. Cox's site you can clearly see the two valves.

Pressure in the crankcase pushes the mixture into the cylinder. The pushrod opens the exhaust port to allow the gases to escape. The valve closes and as the piston goes downward it forces fuel mixture back into the cylinder area. Two strokes not four like the usual recip. engines. Only needs one valve since the side walls of the piston equal the other valve by covering and uncovering the hole.

I have a home-made one, it's quite possible if you have contacts with a machine-shop, or someone with good enough home tools. I didn't really know how Waldrons set looked like so a friend and I sat over a couple of whiskys one evening and worked out our own. It's like this: Two pieces of steel, with a milled surface between them. Drill holes (about 5mm) in each corner for guiding rods, my rods are made on a lathe, but you could probably use drill bits. Then drill holes through the whole contraption in various sizes. Thats it! You use drill bit ends as punches, I just put a piece of plastic between the steel pieces, put a drill-bit in the correct hole and tap with a hammer, out comes a perfectly shaped plastic circle.

It popped open at the bottom of the down stroke admitting fuel/air/castor oil mixture and closed as the piston travelled up the cylinder. The one external valve and push rod that you see is the exhaust valve. Alvie Ray Boorman wrote: > I have been looking at some pictures of LeRhone Rotaries.

One large open one where the exhaust gases come out inside the cowling. One on the opposite side has a bronze intake tube near the cylinder head which is mostly one piece with machined ports . The rocker arm works both ways and the pushrod holds the exhaust open or relaxes and allows the spring on the exhaust to push open the intake valve by waqy of the arm across the top of the cylinder head.. I do not believe the push rod has the ability to pull anything. They push or relax. When relaxed the intake is open. When fully pushed the exhaust is open. Steve Perry has provided a vey nice set of photos showing the LeRhone and the Monosoupape engines. http://smperry.home.mindspring.com/lr.htm They are very good to show what is happening on the cylinder tops. The pushrods are activated by an internal cam type device and it has no capacity to pull on the "push" rod "Harris, Mack" wrote: > Lee, you seem to be very knowledgible in this area.

Castor oil does not burn well so a lot of it comes out through the ports or holes in the cowling and even more collects on the wall behind the engine and drips out after landing. > Are these exhausts for the LeRhone or what? > Also, I'm assuming that the different location of the pushrods, (front on > the 80 hp and back on the 110) was just a different design? > Thanks > Mack Harris > ------------------------------ Date: Wed, 1 Nov 2000 13:43:46 -0600 From: "Graham Hunter" To: Subject: RE: LeRhone Rotaries Message-ID: <001401c0443c$0cd84340$fa0101c0@grahamh> -----Original Message----- Of Harris, Mack <> Which two ports are you asking about?

Pressure in the crankcase pushes the mixture into the cylinder. The pushrod opens the exhaust port to allow the gases to escape. The valve closes and as the piston goes downward it forces fuel mixture back into the cylinder area. Two strokes not four like the usual recip. engines. Only needs one valve since the side walls of the piston equal the other valve by covering and uncovering the hole.
