CONDENSATIONThe change from a
gaseous (or vapor) state to a liquid state.
CONTAMINANTDetrimental matter in a
CONTINUITY EQUATIONThe mass rate
of fluid flow into any fixed space is equal to the
mass flow rate out. Hence, the mass flow rate of
fluid past all cross sections of a conduit is equal.
CONTROLA device used to regulate the
function of a component or system.
CONTROL, CYLINDERA control in
which a fluid cylinder is the actuating device.
CONTROL, ELECTRICA control actuated
CONTROL, HYDRAULICA control
actuated by a liquid.
CONTROL, MANUALA control actuated
by the operator.
CONTROL, MECHANICALA control
actuated by linkages, gears, screws, cams, or other
CONTROL, PNEUMATICA control
actuated by air or other gas pressure.
CONTROL, SERVOA control actuated by
a feedback system that compares the output with
the reference signal and makes corrections to
reduce the difference.
CONTROLS, PUMPControls applied to
positive-displacement variable delivery pumps to
adjust their volumetric output or direction of
CONVERGENTThat which inclines and
approaches nearer together, as the inner walls of
a tube that is constricted.
COOLERA heat exchanger, which removes
heat from a fluid.
COOLER, AFTERCOOLERA device that
cools a gas after it has been compressed.
COOLER, INTERCOOLERA device that
cools a gas between the compressive steps of a
multiple stage compressor.
COOLER, PRECOOLERA device that
cools a gas before it is compressed.
CORROSIONThe slow destruction of
materials by chemical agents and electromechanical
CYCLEA single complete operation
consisting of progressive phases starting and
ending at the neutral position.
CYLINDERA device that converts fluid
power into linear mechanical force and motion.
It usually consists of a movable element, such as
a piston and piston rod, plunger, or ram,
operating within a cylindrical bore.
CYLINDER, CUSHIONEDA cylinder with
a piston-assembly deceleration device at one of
both ends of the stroke.
cylinder in which fluid force can be applied to the
movable element in either direction.
CYLINDER, DOUBLE-RODA cylinder
with a single piston and a piston rod extending
from each end.
CYLINDER, DUAL-STROKEA cylinder
combination that provides two working strokes.
CYLINDER, PISTONA cylinder in which
the movable element has a greater cross-sectional
area than the piston rod.
CYLINDER, PLUNGERA cylinder in
which the movable element has the same cross-
sectional area as the piston rod.
CYLINDER, SINGLE-ACTINGA cylinder
in which the fluid force can be applied to the
movable element in only one direction.
CYLINDER, SINGLE-RODA cylinder
with a piston rod extending from one end.
CYLINDER, SPRING-RETURNA cylin-
der in which a spring returns the piston assembly.
CYLINDER, TANDEMTwo or more
cylinders with interconnected piston assemblies.
CYLINDER, TELESCOPINGA cylinder
with nested multiple tubular rod segments which
provide a long working stroke in a short retracted
