Marine Hydraulic Steering System Diagram

The autopilot cylinder unloader valve is a line mounted valve that is used to bypass the hydraulic steering cylinder to enable the boat to be steered manually. A hydraulic steering gear consists of a bridge control which applies helm an engine control which is operated jointly by the helm and hunting gear when fitted and a power pump and rudder actuator which constitutes the steering engine.

Better feel for the road meet better feel for the water.

Marine hydraulic steering system diagram. Below is an example of a jog lever steering system complete with provisions with a backup steering wheel helm pump. The internal valve assembly acts as a check valve. The use of small pistons and ball bearings makes the pump action very smoothnothing like a normal piston pump.

Hardin marine suggests the use of part 137 9309 mandrel for proper installation of hose end. Consists of electric motor driven pumping units a divided reservoir with tank accessories directional control valves system motion control relief and check valves gauges and suction and return line filtration.

Remote mount reservoir installation before installing the remote mount power steering reservoir the stock fill cap on the power steering pump must be removed and replaced with the power steering return dump cap provided. Much like the power steering system in your car or truck. In this example we chose to use two accu steer hrp 35 reversing pumps with the lines combined.

Uses hydraulic pumps and fluid to take the effort out of steering. In this article we will learn about the hydraulic steering systems used in marine applications. This 12 watt solenoid operated valve is available in 12 and 24 vdc and can be used in systems up to 72 bar.

Steering gear system the steering gear system has three main parts. Parts of a hydraulic system. Relatively new to the marine market.

Transmission to the rudder stock. With power steering you have a 2nd hydraulic pump that is driven by an external power source an engine or electric motor not just your arm and through a series shuttles block or pilot operated valves hoses etc the output of this secondary pump is fed into the steering system to supplement. The pump is activated by turning the steering wheel which causes a swash plate to press on a series of small piston pumps.
