Electrohydraulic servo valves may consist of one or more stages. A single-stage servo valve uses a torque motor to directly position a spool valve. Single-stage servo valves suffer from limitations in flow capability and stability due to torque motor power requirements.
Electro-hydraulic actuators (EHAs), replace hydraulic systems with self-contained actuators operated solely by electrical power. EHAs eliminate the need for separate hydraulic pumps and tubing, because they include their own pump, [1] simplifying system architectures and improving safety and reliability. This technology originally was developed ...
Moog also worked on several space contracts and designed part of the liquid rocket engine propulsion systems on the Voyager space probes and provided thruster valves that steered the spacecraft. Moog also made servo-actuators for four Space Shuttles. Moog provided a control and motion system for the Wimbledon Centre Court retracting roof. This ...
A seismic vibrator transforms the energy provided by a diesel engine into a vibration. It is performed by a shaker, a movable element that generates the vibration thanks to a piston-reaction mass device driven by an electrohydraulic servo valve. The shaker is applied to the ground for each vibration, then raised up so that the seismic vibrator ...
Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft's control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens. A hard disk drive has a magnetic servo system with sub-micrometer positioning accuracy ...
An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.
MapQuest appears to be poking fun at President Trump's recent rebranding of the Gulf of Mexico. Here's a look at the new names people have given it.
Sensotronic Brake Control (SBC) is an electro-hydraulic brake system developed by Daimler and Bosch. In this system, the wheel brake cylinders of a vehicle are operated through a servomechanism, offering precise and responsive braking. The SBC system was first introduced on the R230 SL-class, which was released in Europe in October 2001. [1]
