Zusammenfassung:	A continuously variable transmission pulley includes a body defining a hollow tube having a longitudinal central bore. Multiple cylinders are fixed to the body each having a cylinder bore in fluid communication with the longitudinal central bore. A piston is slidably positioned in the cylinder bore of each of the cylinders. A pressurized fluid present in the central bore acts equally against each of the pistons to equally outwardly displace the pistons. A biasing member is connected to each piston and is in direct contact with the pressurized fluid. A friction member is connected to a free end of each of the pistons. Diametrically opposed ones of the friction members define a pulley diameter that varies depending on a portion of the diametrically opposed ones of the pistons extending outwardly from the cylinders.
