摘要

A method of cooling the hydraulic fluid in a power steering system comprising feeding said fluid to and from a storage tank 1 which has a common wall 3 with an adjacent tank 2 for coolant whereby said common wall acts as a heat exchanging interface for cooling the hydraulic fluid as it flows through the storage tank. The method is particularly applicable to motor vehicles in that the coolant tank can be the water reservoir for supplying water to the windscreen and/or headlamp washing systems of the vehicle.
