Pumps produce flow. _________ is resistance to flow

Hydraulic pumps, like any positive-displacement pump, thus require overpressure protection generally in the form of a__________. Over-pressure relief is often built into the pump itself

Two major pumps used in the predominant Electro-Hydraulic Steering Gear Systems.

These devices mediate the coordination between the generated hydraulic pressure from pumps and the rudder stock by converting it into a mechanical force creating a turning moment for the rudder

This pump use axially mounted pistons that reciprocate within internal cylinders to create alternating suction and discharge flow

This pump arranges a series of pistons radially around a rotor hub

Due to piston and cylinder wear, there will be slippage of oil through. Rudder cannot be kept in helm as the pump cannot provide effective hydraulic locking and this is called.

This device is a feedback mechanism of steering gear which repositions the floating lever of hydraulic pump as the tiller moves to the desire position. It will take action to return the rudder in ordered position.

The rotation of the __________ moves the hunting gear returning the operating rod for the pump to the neutral position once the rudder has reached the correct angle.

This device connects the bottom hanging lever of hunting gear to the tiller arm as feedback link to rudder movement. Its purpose is to absorb the difference between the steering order speeds and follow up speed.

These devices are set to lift at a pressure and are intended to allow the rudder to give way when it is subjected to a severe shock from a heavy sea or other causes.

This steering mode is the most common way to steer a vessel when in restricted waters.

This steering mode is a back-up method of steering that can be used in the event that the follow-up mode fails.

Steering mode that is generally used when a vessel is sailing in open waters.
