Eternal BZZ OSPB Power Steering Unit
The hydraulic power steering control units consists of a rotary and a rotary meter. Via a steering column the steering unit is connected to the steering wheel of vehicle. When the steering wheel is turned, oil is directed from the steering system pump via the rotary valve and rotary meter to the cylinder ports L or R(depend on the direction of turn). The rotary meter the oil flow to the steering cylinder in proportion to the angular rotation of the steering wheel.

Features of Eternal power steering unit
- Low cost, reliable.
- No load reaction on the steering wheel comfortable.
- Manual operation available when the pump doesnt work.
- Low control torque, continuous operation.
- According to the system, different function and pressure level valves available.
Characteristic features of electro-hydraulic steering system OSPB, OSPC, OSPR,OSPD:
- High steering pressure requiring smaller cylinders and flow
- Low noise emmission in the cab because of low pilot pressure
- The possibility of emergency steering even on very heavy vehicles
- Minimization of side acceleration with articulated steering
- With microcontroller: No steering wheel drift and the possibility of variable steering ratio
- Analogue and CAN-bus interface
- Electro-hydraulic steering valve EHPS can be combined with Sauer-Danfoss PVG 32 proportional valve
- The system is approved by TÜV and have a controller with satisfy critical steering software
