Abstract
A ship's steering gear of the type operated by liquid under pressure incorporates two liquid systems each containing a pump fed from its own supply tank and a thruster unit capable of providing by itself steering action on a steering member. The two systems are interconnected by way of an isolating valve device. Each tank contains a liquid detecting device arranged on a drop of liquid level in that tank first to close the isolating valve device and on further drop of liquid level to stop the pump fed from the tank and start the pump in the other liquid system if it is not operating already.
