ABSTRACT:
A simplified fluid flow resistance device and exercise equipment utilizing the same is disclosed. In a preferred embodiment, a rotating shaft is centered in a fluid filled sealed cylinder. A rotor is connected to the shaft and a baffle is connected to the internal wall of the cylinder. Rotation of the rotor in the cylinder drives fluid through bores in the baffle. Adjustable spring loaded ball valves are situated in at least two bores passing through the baffle so that resistance to fluid flow through the baffle in opposite directions can be controlled. The simplified design of the fluid flow resistance device of the present invention utilizes less materials so as to have minimal weight; thus the fluid resistance device is ideal for use in spacecrafts. Further, by use of spring loaded one way valves, the device can be used in any orientation, and a minimum resistance to motion of a lever arm connected to the fluid resistance device can be obtained.
