What is a pump/motor?
100

The natural science that studies matter and its motion and behavior through space and time and that studies the related entities of energy and force.

What is physics?
100

A container for keeping a supply of working fluid in a hydraulic system.

What is a reservoir?
100
These are the controls of the hydraulic system.
What are valves?
100
Hydraulic accumulators store this.
What is energy?

What is/are valve(s)?
200

The engineering science of liquid pressure and flow.

What is hydraulics?
200

The measure of resistance of a fluid to flow.

What is viscosity?
200

The three main types of control valves are: pressure, directional, and this.

What is volume control?
200
A hydraulic pump converts ___________ force into ___________ force.
What is mechanical force into hydraulic force?
300
An open rectangle.
What is a vented reservoir?
300

The branch of physics or technology concerned with the mechanical properties of gases.

What is pneumatics?
300

A container which stores fluids under pressure as a source of hydraulic power. 

What is an accumulator?
300
Higher pressures in a hydraulic system can damage the components. This type of valve remedies this danger.
What is a relief valve?
300
This is the most frequent cause of hydraulic pump failure.
What is human error?
400
A white triangle with a black outline.
What is pneumatic?
400

The engineering science of the energy of liquids at rest.

What is hydrostatics?
400

A device which converts hydraulic power into mechanical force and motion.

What is an actuator?
400

Used to control the timing of flow to various branches of a circuit based on pressure.

What is pressure sequence valve?

400
This type of directional control valve is used most often.
What is the spool valve?
500
A horizontal line with an x at one end.
What is a plugged port?
500

The engineering science of the energy of liquid pressure and flow.

What is hydrodynamics?
500

A phenomenon which occurs when the pressure at a point in a hydraulic system is lowered below the vapor pressure of the oil in the system. 

What is cavitation?
500

Automatically adjusts flow depending on raise or decrease in pressure.

What is compensating flow control valve?

500
Piston type cylinders give this type of movement, while vane-type cylinders give this type.
What is straight and rotary?
