POWER STEERING PUMP FOR A VEHICLE

摘要

A power steering pump for a vehicle is provided to prevent deterioration of the pump efficiency due to temperature increase by decreasing the temperature of the power steering pump. A power steering pump for a vehicle comprises a pulley(1). The pulley(1) comprises a disk-shaped cylindrical plate(14) provided at one side of a driving shaft of the power steering pump. A driving hole(15) passes through the center of the cylindrical plate(14). Tooling holes(13) are formed in the cylindrical plate(14), apart from the driving hole(15). A cooling blade(10) is provided between the tooling holes(13) on the cylindrical plate(14). A flange(12) is formed on the outer circumference of the cylindrical plate(14) while being integrally formed with the cylindrical plate(14).
