Abstract
This exercise machine offers isometric and isokinetic exercise by regulating the speed of fluid flowing through the machine's hydraulic system. The consistent speed of the moveable elements on the machine prevents injury and enhances strength training of the targeted muscle groups by maintaining constant strain on those muscles throughout the exercise. This method incorporates both a PTCFC valve and a check valve device to compensates for both pressure and temperature variations within the hydraulic system over time. Additional machine elements allow for analysis of the user's strength through data and graphical displays.
Claims8
An exercise apparatus comprising:
- a. a cabinet comprising at least one linear bearing rail;
- b. a carriage having a mass and moveably seated within the linear bearing rail;
- c. a counterweight having sufficient mass to offset the mass of the carriage;
- d. a set of pulleys mechanically affixed to the cabinet;
- e. a moveable sheave block;
- f. a first wire rope connecting the counterweight to the carriage via one or more pulleys;
- g. a second wire rope that is fixed to the cabinet at one end and connects the moveable sheave block to the counterweight via one or more pulleys;
- h. a closed loop hydraulic system mechanically fastened to the moveable sheave block and comprising a piston moveably seated within a cylinder and in fluid communication with a pressure and temperature compensating flow control valve (PTCFC valve) wherein said PTCFC valve comprises a pressure compensating device, a temperature compensating device, a flow rate orifice needle, and a speed adjustment mechanism mechanically connected to said flow rate orifice needle, and wherein a reverse flow check device is integral to or in fluid communication with the PTCFC valve.
