When the engine is running, fluid from the reservoir flows through the low-pressure suction line to the power steering pump. The fluid passes through the pump and is supplied under pressure to the outlet. Through the high-pressure hose with an attenuator, the fluid flows to the hydraulic distributor of the steering gear.
If there is no effort on the steering wheel, the restriction in the system is minimal and the pump produces low pressure. Minimal pressure is applied to each end of the piston in the hydraulic cylinder via the control valve and all fluid flow from the power steering pump returns to the reservoir via the fluid cooler.
When force is applied to the steering wheel in any direction, the return flow of fluid to the reservoir is restricted and the pressure created by the pump increases. The pressurized fluid is directed through the control valve to the corresponding end of the piston in the hydraulic cylinder, providing increased power and reduced effort required to turn the steering wheel. Fluid displaced from the low-pressure side of the cylinder returns to the reservoir through the control valve and the working fluid cooler. The working fluid cooler reduces the temperature of the fluid, which extends the service life of the hoses and seals of the system.
