  2. Quick return mechanism - Wikipedia

    en.wikipedia.org/wiki/Quick_return_mechanism

    Quick return applied to a shaper. A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.

  3. Hydraulic machinery - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_machinery

    A simple open center hydraulic circuit. An excavator; main hydraulics: Boom cylinders, swing drive, cooler fan, and trackdrive Fundamental features of using hydraulics compared to mechanics for force and torque increase/decrease in a transmission. Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a ...

  4. Fluidics - Wikipedia

    en.wikipedia.org/wiki/Fluidics

    A module with two input streams at the top, an AND output bucket in the middle, and an XOR output stream at the bottom.. Fluidics, or fluidic logic, is the use of a fluid to perform analog or digital operations similar to those performed with electronics.

  5. Electrohydraulic servo valve - Wikipedia

    en.wikipedia.org/wiki/Electrohydraulic_servo_valve

    A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump. It then transfers the fluid to a hydraulic cylinder in a closely controlled manner. Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate.

  6. Shaper - Wikipedia

    en.wikipedia.org/wiki/Shaper

    Shaper tool slide, clapper box and cutting tool Shaper with boring bar setup to allow cutting of internal features, such as keyways, or even shapes that might otherwise be cut with wire EDM In machining , a shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear ...

  7. Fluid power - Wikipedia

    en.wikipedia.org/wiki/Fluid_power

    A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.

  8. Hydraulic manifold - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_manifold

    A hydraulic manifold is a component that regulates fluid flow between pumps and actuators and other components in a hydraulic system. It is like a switchboard in an electrical circuit because it lets the operator control how much fluid flows between which components of a hydraulic machinery.

  9. Electro-hydraulic actuator - Wikipedia

    en.wikipedia.org/wiki/Electro-hydraulic_actuator

    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 ...
