ABSTRACT:
This invention relates to a new valve module which is particularly suitable for use in an exercise device. The valve module comprises a housing, at least one entrance conduit to allow air to enter the valve module, at least one exit conduit to allow air to exit from the valve module and a pair of valves to control the flow of air through the module. The module is particularly suitable in a variety of exercise devices used in the field of muscle development, exercise and rehabilitation. These devices including the novel module allow for isometric, concentric and eccentric contractions and allow for differing velocities of exercise movement. These devices may be manufactured and sold for home use and require no auxiliary fluid supply source and are completely self contained.
