The Cam Elements

The cam elements have a profile which makes it possible to build up a system giving a linear function between the hydraulic flow and speed of the cam elements and a linear function between the force generated and the hydraulic pressure. The cam elements can be connected together to form any size and configuration of rings or bars. It can also be single, double or multiplied in parallel.

The drive system can have stationary cam elements with moving piston assemblies, or alternatively, stationary piston assemblies with moving cam elements.

The cam elements can be made of many different materials, such as steel, plastic, concrete, composites or rubber. Many different lubricants are also possible, such as grease, oil, water or no lubricant at all. Tests must be performed to approximate life cycle data for each combination of material and lubrication.
