![]() ![]() Let's take a look at some advances we'll see in coming years that will help improve efficiency. ![]() It turns out that this type of power-steering system is pretty inefficient. But if the spool valve is turned one way or the other, ports open up to provide high-pressure fluid to the appropriate line. When the steering wheel is not being turned, both hydraulic lines provide the same amount of pressure to the steering gear. Since the inner part of the spool valve is also connected to the steering shaft (and therefore to the steering wheel), the amount of rotation between the inner and outer parts of the spool valve depends on how much torque the driver applies to the steering wheel. The torsion bar also turns the output of the steering gear, connecting to either the pinion gear or the worm gear depending on which type of steering the car has.Īnimation showing what happens inside the rotary valve when you first start to turn the steering wheelĪs the bar twists, it rotates the inside of the spool valve relative to the outside. The bottom of the torsion bar connects to the outer part of the spool valve. It also connects to the top end of the torsion bar. The input from the steering shaft forms the inner part of a spool-valve assembly. The more torque the driver uses to turn the wheels, the more the bar twists. The top of the bar is connected to the steering wheel, and the bottom of the bar is connected to the pinion or worm gear (which turns the wheels), so the amount of torque in the torsion bar is equal to the amount of torque the driver is using to turn the wheels. The torsion bar is a thin rod of metal that twists when torque is applied to it. The key to the rotary valve is a torsion bar. The device that senses the force on the steering wheel is called the rotary valve. When the driver is not exerting force (such as when driving in a straight line), the system shouldn't provide any assist. The pump contains a pressure-relief valve to make sure that the pressure does not get too high, especially at high engine speeds when so much fluid is being pumped.Ī power-steering system should assist the driver only when he is exerting force on the steering wheel (such as when starting a turn). ![]() As a result, the pump moves much more fluid than necessary when the engine is running at faster speeds. Choose Same Day Store Pickup at checkout online to get your El Camino power steering hose replacement today and take advantage of our free engine diagnostic. The pump must be designed to provide adequate flow when the engine is idling. A new power steering pressure hose for Chevy El Camino from AutoZone has the proper fittings and high-quality crimps that prevent future leaks and restore your vehicle's steering input. The amount of flow provided by the pump depends on the car's engine speed. As the vanes spin, they pull hydraulic fluid from the return line at low pressure and force it into the outlet at high pressure. ![]()
