  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. 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 ...

  5. Surface grinding - Wikipedia

    en.wikipedia.org/wiki/Surface_grinding

    The machine consists of a table that traverses both longitudinally and across the face of the wheel. The longitudinal feed is usually powered by hydraulics, as may the cross feed, however any mixture of hand, electrical or hydraulic may be used depending on the ultimate usage of the machine (i.e., production, workshop, cost). The grinding wheel ...

  6. 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.

  7. Actuator - Wikipedia

    en.wikipedia.org/wiki/Actuator

    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.

  8. 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.

  9. 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.
