Hydraulic Steering Systems

Description of LS Hydraulic Steering Systems

As a general rule, the basic set up of a steering system includes:

  • 1 Cylinder,
  • 1 Manual pump,
  • Fittings and tubing to connect the cylinder to the manual pump.

Other elements will be added to this basic set up in function of the number of steering stations, the number of outboard motors to be operated and the addition of a power pack for the automatic pilot.

Cylinder

The cylinder is the dictating element towards the selection of a system as it gives the power to the steering system. To select a cylinder, follow the instruction Selection of the steering system.

  Pump 20-26-30-35-40-50-HB

Manual pump

The manual pump is an axial piston pump which sucks and forces back the oil contained in the circuit when the wheel is operated. Its cubic capacity determines the number of turns required for a lock to lock manoeuvre of the motor(s). The pump is fitted with lock valves to prevent inopportune motor movement when the helm is not operated. The pump is also fitted with pressure relief valves to protect the circuit against abnormal pressure increase.

 

   tubing

Tubing

Tubing is designed for hydraulic transfer under pressure and is easily integrated in the installation as a result of its flexibility and small bending radius. Tubing diameter is selected in function of the manual helm pump flow rate.
