Abstract
A rotating cylinder valve for a two-stroke engine exhaust has an outer cylinder A with inner rotating cylinder A1 with holes PH to allow the passage of engine exhaust gases. The cylinder A1 is driven from the engine crankshaft by a toothed belt and the drive shaft A2 is supported in bearings B2 in a housing B1 mounted in the cylinder A. <IMAGE>
Description
ROTATING Cy1jIER VALVE This invention relates to a Rotating Cylinder Valve.
Two stroke engines are mostly fitted in motor cycles, they are also raced at a high standard.
According to the present invention which consists of a rotating cylinder inside the body of another outer cylinder.
This cylinder has a flange for it to be fixed to any two stroke engine where the exhaust normally fits.
A specific embodiment of the invention will now be described by way of drawings with reference numbers.
Figure 1 shows the rotating cylinder body with attachment flange.
Figure 2 illustrates the separation of the rotating cylinder
from the body or outer cylinder.
Figure 3 shows the rotating cylinder with a view of the cut out
port holes.
Figure 4 shows the drive shaft, the shaft bearings, a heat
shield and the toothed drive wheel.
Figure 5 illustrates the bearing housing where bearings are
fitted either side.
REFERIt'G TO THE DRAWINGS The Rotating Cylinder valve has a body A with a flange D1 to secure it to any two stroke engine.
Inside this body A runs a rotating cylinder Al it consists of two cut out ports PH when rotated the port holes PH come in line with the port holes C/B when timed to engine speed.
The rotating cylinder valve Al is driven by a shaft A2 with a toothed drive wheel 33 attached to the one end this drive wheel B3 is driven by a toothed rubber belt B4 which runs onto another drive sheel of the same size as B3 on the engine crank.
The shaft A2 runs on bearings 32 situated in a housing B1 there are two bearings 32 on either side of the housing B1 for stability.
There is a heat shield A3 fitted on the drive shaft A2 between the rotating cylinder Al and the bearing housing B1 to protect heat damage to the bearings B2.
