The figure shows a cross section through a tubular design. The moving part of the machine is a relative heavy piston consisting of magnets, iron and two or more bearing/sealing surfaces which slide against the cylinder wall in the housing. When the piston is moving in one direction Newtons first law will cause the casing to move in the opposite direction. The casing will then pound like a hammer.
Inside the hosing on each side of the piston there is presurized gas which acts as two very stiff spring. In the wall of the housing there are coils. An electromagnetic force will work from the coils on the piston when currents flows int the coils. By alternating the direction of the current in the coils it is posible to controll direction of the electromagnetic force
What is unique with our concept?
Our patented double gas spring allows a large mass to oscillate at high frequency and long stroke length. Our machine can then deliver power magnitudes larger then what is available today.
What is a linear engine?
Most engines have a rotating part. A linear engine hasn’t! Instead the engines piston moves along a straight line.
What are the advantages and disadvantages?
If your application is linear you eliminate the flywheel, the crankshaft and the piston rod! The wear and tear on the piston is also reduced since the normal force caused by the angle between the piston rod and the piston movement direction disappears.
There is no rotational energy stored in the machine, so that there is no movement at end positions and no work or generation being done in this position.
