摘要： A variable resistance device (100) is adapted to be incorporated in an exercise machine to provide variable resistance. The device has a primary fluid chamber (1). A rotating mechanism (2) rotates within the primary chamber (1). The rotation mechanism (2) upon rotation encounters a degree of resistance dependent on the amount of fluid in the primary chamber (1). A secondary chamber (3) is positioned within or proximate the primary chamber (1). The secondary chamber (3) achieves and maintains an appropriate amount of the fluid in the primary chamber (1) to provide a selected degree of resistance for the exercise machine. Fluid flows through the primary chamber (1) into the secondary chamber (3) and then back into the primary chamber (1). Variable control of the flow of fluid serves to establish and maintain the appropriate amount of fluid in the primary chamber required for a certain degree of resistance; and can provide differing degrees of resistance for the exercise machine.
