A fluid conductor which provides multiple connection ports.
Control: A control actuated by the operator, regardless of the
means of actuation Example, lever or foot pedal control for directional
Control: Any control actuated by linkages, gear, screws, cams
or other mechanical elements.
o regulate the rate of fluid flow.
Time Constant: The time for an energized DC motor to reach 2/3rds
of its set velocity. Based on fixed voltage applied to the windings.
One millionth of a meter or about 0.00004 inch.
A digital computer based on a single miniature integrated circuit
that offers programmability and computational ability for use in
electrohydraulic control application.
Instability: Designates the condition resulting from energizing
a motor at a multiple of its natural frequency (usually the third
orders condition). Torque loss and oscillation can occur in underdamped
An electronic control technique that proportions the current in
a step motor's windings to provide additional intermediate positions
between poles. Produces smooth rotation over a wide speed range
and high positional resolution.
A device which converts hydraulic fluid power into mechanical
force and motion. It usually provides rotary mechanical motion.
A device (VOM or DMM) used to measure electrical quantities.
