Engineering · Steering Gear — Hydraulics
In a hydraulic steering gear, the device that prevents over-pressure when the rudder is forced by a heavy sea is the:
- ARelief (shock/bypass) valve✓ Correct
- BTelemotor
- CRudder angle indicator
- DHunting gear
Explanation
Shock/relief valves limit pressure spikes when external forces (heavy seas) act on the rudder, protecting the rams, piping, and pumps. They are required to be set above the maximum working pressure but below the design pressure of the system.
