ABSTRACT:
A hydraulic control system provides various internal mechanisms for the control of the internal resistance of the telescoping cylinders of the system. Various devices and principles are provided for the external or remote adjustment of the internal resistance control mechanisms of the cylinders. In addition, various types of readouts are provided in order to determine the internal working condition(s) of the cylinder(s). Fluid systems (hydraulic or pneumatic) are provided for the determination of the working condition and internal resistance adjustment of a single cylinder, and further for such determination and adjustment of plural cylinders either collectively or independently. The system is particularly adaptable to use with exercise machines of various types, allowing the user of such a machine to adjust the internal resistance of the cylinder, and to determine the amount of work being expended due to the readout of the internal working condition of the cylinder. The system is also adaptable to individual or collective control of plural shock absorbers, as in a vehicle suspension system, and to the individual or collective readout of the working condition of such shock absorbers.
