CONDENSATION—The change from agaseous (or vapor) state to a liquid state.CONTAMINANT—Detrimental matter in afluid.CONTINUITY EQUATION—The mass rateof fluid flow into any fixed space is equal to themass flow rate out. Hence, the mass flow rate offluid past all cross sections of a conduit is equal.CONTROL—A device used to regulate thefunction of a component or system.CONTROL, CYLINDER—A control inwhich a fluid cylinder is the actuating device.CONTROL, ELECTRIC—A control actuatedelectrically.CONTROL, HYDRAULIC—A controlactuated by a liquid.CONTROL, MANUAL—A control actuatedby the operator.CONTROL, MECHANICAL—A controlactuated by linkages, gears, screws, cams, or othermechanical elements.CONTROL, PNEUMATIC—A controlactuated by air or other gas pressure.CONTROL, SERVO—A control actuated bya feedback system that compares the output withthe reference signal and makes corrections toreduce the difference.CONTROLS, PUMP—Controls applied topositive-displacement variable delivery pumps toadjust their volumetric output or direction offlow.CONVERGENT—That which inclines andapproaches nearer together, as the inner walls ofa tube that is constricted.COOLER—A heat exchanger, which removesheat from a fluid.COOLER, AFTERCOOLER—A device thatcools a gas after it has been compressed.COOLER, INTERCOOLER—A device thatcools a gas between the compressive steps of amultiple stage compressor.COOLER, PRECOOLER—A device thatcools a gas before it is compressed.CORROSION—The slow destruction ofmaterials by chemical agents and electromechanicalreactions.CYCLE—A single complete operationconsisting of progressive phases starting andending at the neutral position.CYLINDER—A device that converts fluidpower into linear mechanical force and motion.It usually consists of a movable element, such asa piston and piston rod, plunger, or ram,operating within a cylindrical bore.CYLINDER, CUSHIONED—A cylinder witha piston-assembly deceleration device at one ofboth ends of the stroke.CYLINDER,DOUBLE-ACTING—Acylinder in which fluid force can be applied to themovable element in either direction.CYLINDER, DOUBLE-ROD—A cylinderwith a single piston and a piston rod extendingfrom each end.CYLINDER, DUAL-STROKE—A cylindercombination that provides two working strokes.CYLINDER, PISTON—A cylinder in whichthe movable element has a greater cross-sectionalarea than the piston rod.CYLINDER, PLUNGER—A cylinder inwhich the movable element has the same cross-sectional area as the piston rod.CYLINDER, SINGLE-ACTING—A cylinderin which the fluid force can be applied to themovable element in only one direction.CYLINDER, SINGLE-ROD—A cylinderwith a piston rod extending from one end.CYLINDER, SPRING-RETURN—A cylin-der in which a spring returns the piston assembly.CYLINDER, TANDEM—Two or morecylinders with interconnected piston assemblies.CYLINDER, TELESCOPING—A cylinderwith nested multiple tubular rod segments whichprovide a long working stroke in a short retractedenvelope.AI-2
