The Powerkurver construction details show clearly that it was fully designed for its intended purpose. The uncompromising quality of all its components assure a long, dependable operation even under the most rigorous conditions.
The Powerkurver piston generates a force proportional to the air pressure. The piston pushes heavy-duty rollers against the curve in the rotating cam link. The housing takes up the corresponding reaction forces.
The unique, expressly developed and patented curve shape produces a constant torque of the cam link within a predetermined range of the operating angle. The principle behind the force is the 'inclined plane theory'.
