Abstract
An exercise resistance device operably connected to reciprocating members of an exercise machines may include a closed fluid flow system enclosed in an inner housing. Reciprocal movement of the reciprocating members alternately rotates a drive gear and driven gear in clockwise and counterclockwise directions pumping fluid from a low pressure fluid passagewayway into a high pressure fluid passagewayway of the closed fluid flow system. A spool valve is movable to maintain a heat exchanger and flow control valve in fluid communication with the high pressure fluid flow passageway regardless of the rotation direction of the drive gear and driven gear. Adjustment of a flow control valve adjusts the speed/resistance of the exercise machine. An outer housing partially enclosing the inner housing provides containment of fluid leaks.
