Abstract
A hydraulic resistive apparatus that is used in exercise equipment includes a resistive device and a heat dissipating device. The resistive device includes a cylinder and a piston that are movable relative to one another. A working fluid is contained within the cylinder. The heat dissipating device is securely engaged to the outside of the cylinder and includes a tubular body having a plurality of cooling fins extending from its external surface. As heat is generated by the relative movement of the cylinder and piston, it is conducted to the heat dissipating device and then radiated into the surrounding environment. The body of the heat dissipating device includes a longitudinal slit that permits temporary opening of the body so as to permit it to be slid onto the cylinder and, when released, results in full surface-to-surface contact between the heat dissipating device and cylinder.
