DSL 106 W11 D2 Final Flashcard

Front

What is a Directional Control Valve (DCV)?

Back

A valve that directs the flow of hydraulic fluid in a hydraulic system, allowing control over the movement of actuators.

Front

What is the role of compensator valves in a hydraulic system?

Back

They further restrict and ration flow to the actuators proportionally, ensuring efficient operation.

Front

What is the function of hydraulic cylinders in articulation steering?

Back

To pivot the two frames of a machine, enabling it to steer left or right.

Front

What are the benefits of using a smaller pump in hydraulic systems?

Back

Reduces cost, saves space or weight, and conserves hydraulic or engine horsepower.

Front

What is a non-positive-displacement pump?

Back

A pump that moves fluid without trapping a fixed amount of fluid, allowing for variable flow rates.

Front

What is the function of a rotary valve in power steering?

Back

It acts as a Directional Control Valve (DCV), directing fluid flow to assist in steering.

Front

What is a Pressure Control Valve (PCV)?

Back

A valve that regulates the pressure in a hydraulic system to prevent damage and ensure safe operation.

Front

What is the purpose of an Automatic Control Valve (ACV)?

Back

To automatically adjust the flow or pressure in a hydraulic system based on demand.

Front

What is an Electronic Control Valve (ECV)?

Back

A valve that uses electronic signals to control the flow of hydraulic fluid, allowing for precise operation.

Front

How do compensator valves maintain system pressure?

Back

By adjusting the flow to maintain the highest working pressure in the hydraulic system.
