What is an Orbitrol?

What is an Orbitrol?

The Orbitrol is used principally for hydrostatic power steering systems of industrial vehicles, construction vehicles and boats, but it can be used for some servo-type applications or any applications where visual positioning are required.

What does an orbital valve do?

All of Trail-Gear’s orbitals (steering control valves) have a built in return-to-center function. This means that when the driver releases the wheel the tires will automatically return to the center position. This is a convenient feature that allows for slow rock crawling or driving at higher speeds.

What is a non load reaction steering unit?

A non-load reaction steering unit blocks the cylinder ports in neutral, holding the axle position whenever the operator releases the steering wheel. Load Reaction. A load reaction steering unit couples the cylinder ports internally (in the neutral position) with the meter gear set.

What is a steering valve?

The Steering Control Valve is a part of the hydraulic power steering system. It is used to control the flow of fluid into the steering system. When the car is driving on a straight road, the steering valve remains in position and the fluid flows through the system and into the reservoir.

How do you diagnose a bad power steering valve?

The following are symptoms of a bad or failing power steering control valve.

  1. Leaking power steering fluid. One of the most common problems with the valve is it will start leaking.
  2. Difficulty steering. Is it hard to turn a corner or difficult to park?
  3. Whining noise while turning the wheel.

How does a hydraulic steering valve work?

A hydraulic steering unit consists of a directional control valve and metering section. The valve directs the pressurized oil supplied to and from the cylinder and the metering section. All ports of the steering unit are blocked when the vehicle is not being steered.

How does a hydraulic steering motor work?

Hydraulic power steering systems work by using a hydraulic system to multiply force applied to the steering wheel inputs to the vehicle’s steered (usually front) road wheels. The hydraulic pressure typically comes from a gerotor or rotary vane pump driven by the vehicle’s engine.

What is an open center hydraulic system?

Open center refers to the open central path of the control valve, when the valve is in neutral position. The hydraulic pump is a continuous flow type. When the valve is neutral, then hydraulic fluid goes back to reservoir or the tractor housing. So in a nutshell, open-center systems always have oil flow.

How does a hydraulic helm pump work?

The helm consists of a hydraulic pump and a system of valves, which pumps fluid into the hydraulic lines. The pump is activated by turning the steering wheel, which causes a swashplate to press on a series of small piston pumps.

Which cars still have hydraulic steering?

Today, few cars with hydraulic steering are still available on the mass market, and most that do are light trucks, such as the Toyota Tacoma. One the performance car side of things, one of the only options remaining is the Subaru WRX Sti.

How does Seastar hydraulic steering work?

(SeaStar, BayStar): Two-line manual hydraulic boat steering systems use a helm pump to directly move the hydraulic cylinder. During operation, a clockwise turn of the boat’s steering wheel will force hydraulic fluid from the helm pump unit into the boat’s starboard side hydraulic line.

How do you add hydraulic fluid to a Seastar steering wheel?

Sea Star hydraulic steering fluid is prevalent in most boating centers across the United States.

  1. Thread filler tube into helm pump.
  2. Thread bottle of fluid onto filler tube.
  3. Poke a hole into the bottom of the bottle (or, cut the bottom off and create a funnel)
  4. Turn bottle upside down (like an IV)

What type of fluid goes in a sea star steering system?

Teleflex SeaStar Hydraulic Oil

How does full hydro steering work?

When the steering wheel is moved a valve opens and closes. The valve sends pressurized hydraulic fluid to either end of a hydraulic ram. The ram forces the wheels to turn whichever direction you turned the wheel. Thus the fluid inside the hoses is the only connection between the steering wheel and the steered wheel.

Is full hydro steering street legal?

The law states you have to have a mechanical links that operate the steering, so full hydro is illegal on the road.

What fluid to use in hydro assist?

PSC recommends clear power steering fluid, or Royal Purple.

What is hydraulic assistance?

In a vehicle, hydraulic assist brakes rely on the pressurized fluid that powers the power-steering. The hydraulic brake system will have a line plumbed in with the steering gear. In short, when you apply the brakes, a spool valve that controls the fluid will move and allow pressurized fluid to assist in braking.

Which is better electric or hydraulic power steering?

Electric power steering provides better fuel economy Cars with EPS systems do not come with hydraulic pumps or pistons. Also, the EPS system doesn’t use power from the engine as the hydraulic systems do. Overall, the electric power steering system is more efficient.
