compressibility		The ability of fluids to decrease in volume as a result of applied pressure.
conductor		The components such as pipes, tubes, and hoses that convey fluids throughout a hydraulic or pneumatic system.
control valve		Mechanisms that control fluids in a pneumatic or hydraulic system. Control valves direct fluid movement and regulate the amount of pressure exerted in the fluid system.
cylinder		A type of linear actuator that uses a piston to produce motion in a straight line. A cylinder is also known as a piston actuator.
demulsibility		The resistance of a hydraulic fluid to emulsification, or how well a hydraulic fluid resists mixing with water.

effector		Components that directly help convert hydraulic or pneumatic energy into mechanical energy. Effectors are also known as actuators.
electrical system		A power transmission system that uses the force of flowing electrons to transmit power.
energy		The measure of being able to produce work.
flanging		An operation that bends the edge of a part to add stiffness. Flanging most often creates a 90° bend in the metal.
FLR-unit		A device that conditions air for use in pneumatic systems. A filter-lubricator-pressure-regulator is commonly called an FLR-unit.
fluid		A state of matter that has the ability to flow. Fluids can be liquids or gases.
fluid motor		A device that converts the energy from fluid flow into mechanical motion. Hydraulic and pneumatic motors are fluid motors.
fluid power		Power derived from the motion and pressure of a fluid, such as water or air. Hydraulics and pneumatics are sources of fluid power.
Fluid system		A power transmission system that uses the force of flowing liquids and gases to transmit power. Fluid systems include hydraulic systems and pneumatic systems.
force		The push or pull that changes an object's state of motion.
gas		A fluid without a fixed volume that has the ability to flow and fill the space it occupies.
gear pump		A hydraulic pump that uses meshed gears that rotate and move liquid through a hydraulic system.
gear screw compressor		An air compressor that uses meshed gears that rotate and move air or gas through a pneumatic system.
