Elbow engine

Elbow the engine is a combustion engine, which converts pressure steam or compressed air into mechanical energy.

The name is derived from elbow = elbow. It comprises perpendicularly curved pistons which are flowed through by the medium. The Elbow engine is as good as any technical application, but is happy rebuilt as a demonstration model, not least because of their unique operation.

Operation

The simplistic graphics right to show the principle of operation. Two metal disks ( G and H ) are arranged to rotate on the axes e. The axes are mutually perpendicular. The discs are provided with bores in which the pistons ( F1 and F2) are movably fitted - as indicated by the dashed line in blue flask. In practice, it should be at least three pistons, for clarity only two are shown. The piston itself consist of a round tube. A, B, C and D represent the valves dar. From the outlet valve B there is a connection to the inlet valve C.

Inlet valve A is opened and exhaust valve D closed. The compressed air flows into the flask F1 and tried to push it for ' Up ' - this is so slidably fitted into the glass. By the upward movement of the left-hand wheel is rotated anti-clockwise. The compressed air passes into the piston F2. This is then pressed to the right, and thus rotates the lower disc also left. The pistons reach their dead center, the intake valves are closed and the exhaust valves. What is missing is the valve control, which ensures that in each case is allowed to flow to the piston is in an upward motion, compressed air. This is achieved by a respective fixed disc with corresponding holes is placed below the lower plate and to the left of the left wheel ( not shown in the diagram).

The mechanical energy can be tapped at one of the two disks, which is then also coupled to a flywheel. Note that, generally the two disks are coupled with each other only through the pistons. The axes have no connection with each other.
